The version of IBM HTTP Server running on the remote host is affected by an HTTP request smuggling vulnerability related to Apache HTTP Server. The chunked transfer coding implementation in the Apache HTTP Server before 2.4.14 does not properly parse chunk headers, which allows remote attackers to conduct HTTP request smuggling attacks via a crafted request, related to mishandling of large chunk-size values and invalid chunk-extension characters in modules/http/http_filters.c.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote host is running a version of Mac OS X 10.10.x that is prior to 10.10.5. It is, therefore, affected by multiple vulnerabilities in the following components :

  - apache
  - apache_mod_php
  - Apple ID OD Plug-in
  - AppleGraphicsControl
  - Bluetooth
  - bootp
  - CloudKit
  - CoreMedia Playback

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

The Apache2 webserver was updated to fix several issues :

Security issues fixed :

  - The chunked transfer coding implementation in the Apache     HTTP Server did not properly parse chunk headers, which     allowed remote attackers to conduct HTTP request     smuggling attacks via a crafted request, related to     mishandling of large chunk-size values and invalid     chunk-extension characters in     modules/http/http_filters.c. [bsc#938728, CVE-2015-3183]

  - The LOGJAM security issue was addressed by: [bnc#931723     CVE-2015-4000]

  - changing the SSLCipherSuite cipherstring to disable     export cipher suites and deploy Ephemeral Elliptic-Curve     Diffie-Hellman (ECDHE) ciphers.

  - Adjust 'gensslcert' script to generate a strong and     unique Diffie Hellman Group and append it to the server     certificate file.

  - The ap_some_auth_required function in server/request.c     in the Apache HTTP Server 2.4.x did not consider that a     Require directive may be associated with an     authorization setting rather than an authentication     setting, which allowed remote attackers to bypass     intended access restrictions in opportunistic     circumstances by leveraging the presence of a module     that relies on the 2.2 API behavior. [bnc#938723     bnc#939516 CVE-2015-3185]

  - Tomcat mod_jk information leak due to incorrect     JkMount/JkUnmount directives processing [bnc#927845     CVE-2014-8111]

Other bugs fixed :

  - Now provides a suse_maintenance_mmn_# [bnc#915666].

  - Hard-coded modules in the %files [bnc#444878].

  - Fixed the IfModule directive around SSLSessionCache     [bnc#911159].

  - allow only TCP ports in Yast2 firewall files     [bnc#931002]

  - fixed a regression when some LDAP searches or     comparisons might be done with the wrong credentials     when a backend connection is reused [bnc#930228]

  - Fixed split-logfile2 script [bnc#869790]

  - remove the changed MODULE_MAGIC_NUMBER_MINOR from which     confuses modules the way that they expect functionality     that our apache does not provide [bnc#915666]

  - gensslcert: CN now defaults to `hostname -f`     [bnc#949766], fix help [bnc#949771]

The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server.

Multiple flaws were found in the way httpd parsed HTTP requests and responses using chunked transfer encoding. A remote attacker could use these flaws to create a specially crafted request, which httpd would decode differently from an HTTP proxy software in front of it, possibly leading to HTTP request smuggling attacks. (CVE-2015-3183)

It was discovered that in httpd 2.4, the internal API function ap_some_auth_required() could incorrectly indicate that a request was authenticated even when no authentication was used. An httpd module using this API function could consequently allow access that should have been denied. (CVE-2015-3185)

All httpd users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd service will be restarted automatically.

The IBM HTTP Server running on the remote host is version 6.1 prior to or equal to 6.1.0.47, 7.0 prior to 7.0.0.39, 8.0 prior to 8.0.0.12, or 8.5 prior to 8.5.5.7. It is, therefore, potentially affected by multiple vulnerabilities :

  - An overflow condition exists in the XML_GetBuffer()     function in xmlparse.c due to improper validation of     user-supplied input when handling compressed XML     content. An attacker can exploit this to cause a buffer     overflow, resulting in the execution of arbitrary code.
    (CVE-2015-1283)

  - A denial of service vulnerability exists when processing     an ECParameters structure due to an infinite loop that     occurs when a specified curve is over a malformed binary     polynomial field. A remote attacker can exploit this to     perform a denial of service against any system that     processes public keys, certificate requests, or     certificates. This includes TLS clients and TLS servers     with client authentication enabled. (CVE-2015-1788)

  - An information disclosure vulnerability exists that     allows an unauthenticated, remote attacker to identify     the proxy server software by reading the HTTP 'Via'     header. (CVE-2015-1932)

  - A flaw exists in the chunked transfer coding     implementation due to a failure to properly parse chunk     headers. A remote attacker can exploit this to conduct     HTTP request smuggling attacks. (CVE-2015-3183)

  - An unspecified flaw exists that allows an     unauthenticated, remote attacker to spoof servlets or     disclose sensitive information. (CVE-2015-4938)

  - An overflow condition exists in the Administration     Server due to improper validation of user-supplied     input. An attacker can exploit this, via a specially     crafted request, to cause a stack-based buffer overflow,     resulting in a denial of service condition or the     execution of arbitrary code. (CVE-2015-4947)

Note that :
  - CVE-2015-1788 does not affect the 6.1 and 7.0 branches.
  - CVE-2015-1932 and CVE-2015-4938 do not affect the 6.1     branch.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:1666 advisory.

    The httpd packages provide the Apache HTTP Server, a powerful, efficient,     and extensible web server.

    Multiple flaws were found in the way httpd parsed HTTP requests and     responses using chunked transfer encoding. A remote attacker could use     these flaws to create a specially crafted request, which httpd would decode     differently from an HTTP proxy software in front of it, possibly leading to     HTTP request smuggling attacks. (CVE-2015-3183)

    It was discovered that in httpd 2.4, the internal API function     ap_some_auth_required() could incorrectly indicate that a request was     authenticated even when no authentication was used. An httpd module using     this API function could consequently allow access that should have been     denied. (CVE-2015-3185)

    Note: This update introduces new a new API function,     ap_some_authn_required(), which correctly indicates if a request is     authenticated. External httpd modules using the old API function should be     modified to use the new one to completely resolve this issue.

    A denial of service flaw was found in the way the mod_lua httpd module     processed certain WebSocket Ping requests. A remote attacker could send a     specially crafted WebSocket Ping packet that would cause the httpd child     process to crash. (CVE-2015-0228)

    A NULL pointer dereference flaw was found in the way httpd generated     certain error responses. A remote attacker could possibly use this flaw to     crash the httpd child process using a request that triggers a certain HTTP     error. (CVE-2015-0253)

    All httpd24-httpd users are advised to upgrade to these updated packages,     which contain backported patches to correct these issues. After installing     the updated packages, the httpd24-httpd service will be restarted     automatically.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the httpd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - The log_cookie function in mod_log_config.c in the     mod_log_config module in the Apache HTTP Server before     2.4.8 allows remote attackers to cause a denial of     service (segmentation fault and daemon crash) via a     crafted cookie that is not properly handled during     truncation.(CVE-2014-0098)

  - A race condition flaw, leading to heap-based buffer     overflows, was found in the mod_status httpd module. A     remote attacker able to access a status page served by     mod_status on a server using a threaded     Multi-Processing Module (MPM) could send a specially     crafted request that would cause the httpd child     process to crash or, possibly, allow the attacker to     execute arbitrary code with the privileges of the     'apache' user.(CVE-2014-0226)

  - It was discovered that the HTTP parser in httpd     incorrectly allowed certain characters not permitted by     the HTTP protocol specification to appear unencoded in     HTTP request headers. If httpd was used in conjunction     with a proxy or backend server that interpreted those     characters differently, a remote attacker could     possibly use this flaw to inject data into HTTP     responses, resulting in proxy cache     poisoning.(CVE-2016-8743)

  - A NULL pointer dereference flaw was found in the way     the mod_cache httpd module handled Content-Type     headers. A malicious HTTP server could cause the httpd     child process to crash when the Apache HTTP server was     configured to proxy to a server with caching     enabled.(CVE-2014-3581)

  - Multiple flaws were found in the way httpd parsed HTTP     requests and responses using chunked transfer encoding.
    A remote attacker could use these flaws to create a     specially crafted request, which httpd would decode     differently from an HTTP proxy software in front of it,     possibly leading to HTTP request smuggling     attacks.(CVE-2015-3183)

  - In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and     2.4.0 to 2.4.29, mod_authnz_ldap, if configured with     AuthLDAPCharsetConfig, uses the Accept-Language header     value to lookup the right charset encoding when     verifying the user's credentials. If the header value     is not present in the charset conversion table, a     fallback mechanism is used to truncate it to a two     characters value to allow a quick retry (for example,     'en-US' is truncated to 'en'). A header value of less     than two characters forces an out of bound write of one     NUL byte to a memory location that is not part of the     string. In the worst case, quite unlikely, the process     would crash which could be used as a Denial of Service     attack. In the more likely case, this memory is already     reserved for future use and the issue has no effect at     all.(CVE-2017-15710)

  - A NULL pointer dereference flaw was found in the     httpd's mod_ssl module. A remote attacker could use     this flaw to cause an httpd child process to crash if     another module used by httpd called a certain API     function during the processing of an HTTPS     request.(CVE-2017-3169)

  - It was discovered that httpd used the value of the     Proxy header from HTTP requests to initialize the     HTTP_PROXY environment variable for CGI scripts, which     in turn was incorrectly used by certain HTTP client     implementations to configure the proxy for outgoing     HTTP requests. A remote attacker could possibly use     this flaw to redirect HTTP requests performed by a CGI     script to an attacker-controlled proxy via a malicious     HTTP request.(CVE-2016-5387)

  - A buffer over-read flaw was found in the httpd's     mod_mime module. A user permitted to modify httpd's     MIME configuration could use this flaw to cause httpd     child process to crash.(CVE-2017-7679)

  - A specially crafted HTTP request header could have     crashed the Apache HTTP Server prior to version 2.4.30     due to an out of bound read while preparing data to be     cached in shared memory. It could be used as a Denial     of Service attack against users of mod_cache_socache.
    The vulnerability is considered as low risk since     mod_cache_socache is not widely used, mod_cache_disk is     not concerned by this vulnerability.(CVE-2018-1303)

  - It was discovered that the httpd's mod_auth_digest     module did not properly initialize memory before using     it when processing certain headers related to digest     authentication. A remote attacker could possibly use     this flaw to disclose potentially sensitive information     or cause httpd child process to crash by sending     specially crafted requests to a server.(CVE-2017-9788)

  - A flaw was found in the way httpd handled HTTP Trailer     headers when processing requests using chunked     encoding. A malicious client could use Trailer headers     to set additional HTTP headers after header processing     was performed by other modules. This could, for     example, lead to a bypass of header restrictions     defined with mod_headers.(CVE-2013-5704)

  - A buffer over-read flaw was found in the httpd's     ap_find_token() function. A remote attacker could use     this flaw to cause httpd child process to crash via a     specially crafted HTTP request.(CVE-2017-7668)

  - A race condition was found in mod_auth_digest when the     web server was running in a threaded MPM configuration.
    It could allow a user with valid credentials to     authenticate using another username, bypassing     configured access control restrictions.(CVE-2019-0217)

  - A NULL pointer dereference flaw was found in the     mod_cache httpd module. A malicious HTTP server could     cause the httpd child process to crash when the Apache     HTTP Server was used as a forward proxy with caching.
    (CVE-2013-4352)

  - he dav_xml_get_cdata function in main/util.c in the     mod_dav module in the Apache HTTP Server before 2.4.8     does not properly remove whitespace characters from     CDATA sections, which allows remote attackers to cause     a denial of service (daemon crash) via a crafted DAV     WRITE request. (CVE-2013-6438)

  - A denial of service flaw was found in the mod_proxy     httpd module. A remote attacker could send a specially     crafted request to a server configured as a reverse     proxy using a threaded Multi-Processing Modules (MPM)     that would cause the httpd child process to crash.
    (CVE-2014-0117)

  - A denial of service flaw was found in the way httpd's     mod_deflate module handled request body decompression     (configured via the 'DEFLATE' input filter). A remote     attacker able to send a request whose body would be     decompressed could use this flaw to consume an     excessive amount of system memory and CPU on the target     system.(CVE-2014-0118)

  - A denial of service flaw was found in the way httpd's     mod_cgid module executed CGI scripts that did not read     data from the standard input. A remote attacker could     submit a specially crafted request that would cause the     httpd child process to hang     indefinitely.(CVE-2014-0231)

  - It was discovered that in httpd 2.4, the internal API     function ap_some_auth_required() could incorrectly     indicate that a request was authenticated even when no     authentication was used. An httpd module using this API     function could consequently allow access that should     have been denied. (CVE-2015-3185)

  - It was discovered that the mod_session_crypto module of     httpd did not use any mechanisms to verify integrity of     the encrypted session data stored in the user's     browser. A remote attacker could use this flaw to     decrypt and modify session data using a padding oracle     attack. (CVE-2016-0736)

  - It was discovered that the mod_auth_digest module of     httpd did not properly check for memory allocation     failures. A remote attacker could use this flaw to     cause httpd child processes to repeatedly crash if the     server used HTTP digest authentication.(CVE-2016-2161)

  - It was discovered that the use of httpd's     ap_get_basic_auth_pw() API function outside of the     authentication phase could lead to authentication     bypass. A remote attacker could possibly use this flaw     to bypass required authentication if the API was used     incorrectly by one of the modules used by     httpd.(CVE-2017-3167)

  - A use-after-free flaw was found in the way httpd     handled invalid and previously unregistered HTTP     methods specified in the Limit directive used in an     .htaccess file. A remote attacker could possibly use     this flaw to disclose portions of the server memory, or     cause httpd child process to crash. (CVE-2017-9798)

  - In Apache httpd 2.2.0 to 2.4.29, when generating an     HTTP Digest authentication challenge, the nonce sent to     prevent reply attacks was not correctly generated using     a pseudo-random seed. In a cluster of servers using a     common Digest authentication configuration, HTTP     requests could be replayed across servers by an     attacker without detection. (CVE-2018-1312)
