The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2338-1 advisory.

  - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of     Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This     issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions.
    (CVE-2022-26377)

  - The ap_rwrite() function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an     attacker can cause the server to reflect very large input using ap_rwrite() or ap_rputs(), such as with     mod_luas r:puts() function. Modules compiled and distributed separately from Apache HTTP Server that use     the 'ap_rputs' function and may pass it a very large (INT_MAX or larger) string must be compiled against     current headers to resolve the issue. (CVE-2022-28614)

  - Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in     ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the     server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may     hypothetically be affected. (CVE-2022-28615)

  - In Apache HTTP Server 2.4.53 and earlier, a malicious request to a lua script that calls r:parsebody(0)     may cause a denial of service due to no default limit on possible input size. (CVE-2022-29404)

  - If Apache HTTP Server 2.4.53 is configured to do transformations with mod_sed in contexts where the input     to mod_sed may be very large, mod_sed may make excessively large memory allocations and trigger an abort.
    (CVE-2022-30522)

  - Apache HTTP Server 2.4.53 and earlier may return lengths to applications calling r:wsread() that point     past the end of the storage allocated for the buffer. (CVE-2022-30556)

  - Apache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based on     client side Connection header hop-by-hop mechanism. This may be used to bypass IP based authentication on     the origin server/application. (CVE-2022-31813)

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 installation on the remote host is affected by the following vulnerabilities :

    Bug Fix(es):

    * proxy rewrite to unix socket fails with CVE-2021-40438 fix (BZ#2022319)

    Additional changes:

    * To fix CVE-2022-29404, the default value for the LimitRequestBody directive in the Apache HTTP Server     has been changed from 0 (unlimited) to 1 GiB.

    On systems where the value of LimitRequestBody is not explicitly specified in an httpd configuration     file, updating the httpd package sets LimitRequestBody to the default value of 1 GiB. As a consequence,     if the total size of the HTTP request body exceeds this 1 GiB default limit, httpd returns the 413 Request     Entity Too Large error code.

    If the new default allowed size of an HTTP request message body is insufficient for your use case, update     your httpd configuration files within the respective context (server, per-directory, per-file, or per-     location) and set your preferred limit in bytes. For example, to set a new 2 GiB limit, use:

    LimitRequestBody 2147483648

    Systems already configured to use any explicit value for the LimitRequestBody directive are unaffected     by this change.

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 :

  - A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL     pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for     requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This     issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). (CVE-2021-44224)

  - A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser     (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the     vulnerability though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and     earlier. (CVE-2021-44790)

  - A carefully crafted request body can cause a read to a random memory area which could cause the process to     crash. This issue affects Apache HTTP Server 2.4.52 and earlier. (CVE-2022-22719)

  - Apache HTTP Server 2.4.52 and earlier fails to close inbound connection when errors are encountered     discarding the request body, exposing the server to HTTP Request Smuggling (CVE-2022-22720)

  - If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems     an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server     2.4.52 and earlier. (CVE-2022-22721)

  - Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap     memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and     prior versions. (CVE-2022-23943)

  - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of     Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This     issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions.

  - 如果在 32 位系统上将 LimitXMLRequestBody 设置为允许处理大于 350MB（默认为 1M）的请求正文，则将导致发生整数溢出，随后导致越界写入问题。此问题影响 Apache HTTP Server 2.4.52 及更早版本。(CVE-2022-22721)

  - Apache HTTP Server 的 mod_sed 中的越界写入漏洞允许攻击者使用可能由攻击者提供的数据覆盖堆内存。此问题影响 Apache HTTP Server 2.4 2.4.52 及之前版本。(CVE-2022-23943)

  - Apache HTTP Server 的 mod_proxy_ajp 中存在对 HTTP 请求解释不一致（“HTTP 请求走私”）漏洞，攻击者可借此将请求走私到其转发请求的 AJP 服务器。此问题影响 Apache HTTP Server 2.4、2.4.53 及之前版本。
    (CVE-2022-26377)

  - Windows 主机上的 Apache HTTP Server 2.4.53 及更早版本中存在越界读取漏洞，当配置为使用 mod_isapi 模块处理请求时，该漏洞可造成越界读取内容。(CVE-2022-28330)

  - 如果攻击者能够使用 ap_rwrite() 或 ap_rputs()（例如使用 mod_luas r:puts() 函数）让服务器反映超大型输入，则 Apache HTTP Server 2.4.53 及更早版本中的 ap_rwrite() 函数。对于使用“ap_rputs”函数并可能向其传递非常大（INT_MAX 或更大）字符串的从 Apache HTTP Server 单独编译和分发的模块，必须针对当前标头进行编译以解决该问题。 (CVE-2022-28614)

  - 在 Apache HTTP Server 2.4.53 及更早版本中，当应用程序处理超大型输入缓冲时，ap_strcmp_match() 中的越界读取漏洞可能会造成程序崩溃或信息泄露。虽然无法将随服务器分发的代码强制转换为此类调用，但使用 ap_strcmp_match() 的第三方模块或 lua 脚本可能会受到影响。(CVE-2022-28615)

  在 Apache HTTP Server 2.4.53 及更早版本中，由于对可能的输入大小没有默认限制，恶意请求调用 r:parsebody(0) 的 lua 脚本可能会造成应用程序拒绝服务。(CVE-2022-29404)

  - 如果将 Apache HTTP Server 2.4.53 配置为在 mod_sed 的输入可能非常大的上下文中使用 mod_sed 执行转换，则 mod_sed 可能会进行超大内存分配并触发中止。
    (CVE-2022-30522)

  - Apache HTTP Server 2.4.53 及更早版本可能会向调用 r: wsread() 的应用程序返回指向超过为缓冲区分配的存储区末尾的长度。(CVE-2022-30556)

  - Apache HTTP Server 2.4.53 及更早版本可能不会根据客户端的 Connection 标头逐跳机制将 X-Forwarded-* 标头发送到源服务器。攻击者可利用此问题绕过源服务器/应用程序上基于 IP 的认证。(CVE-2022-31813)
