The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7180-1 advisory.

    It was discovered that Python incorrectly handled certain scripts. An attacker could possibly use this     issue to execute arbitrary code or cause a crash. (CVE-2022-48560)

    It was discovered that Python did not properly handle XML entity declarations in plist files. An attacker     could possibly use this vulnerability to perform an XML External Entity (XXE) injection, resulting in a     denial of service or information disclosure. (CVE-2022-48565)

    It was discovered that Python did not properly provide constant-time processing for a crypto operation. An     attacker could possibly use this issue to perform a timing attack and recover sensitive information.
    (CVE-2022-48566)

    It was discovered that Python incorrectly handled certain inputs. If a user or an automated system were     tricked into running a specially crafted input, a remote attacker could possibly use this issue to cause a     denial of service. (CVE-2023-24329)

    It was discovered that Python instances of ssl.SSLSocket were vulnerable to a bypass of the TLS handshake.
    An attacker could possibly use this issue to cause applications to treat unauthenticated received data     before TLS handshake as authenticated data after TLS handshake. (CVE-2023-40217)

  - heapq 中的 heappushpop 导致 3.9 及之前的 Python 存在释放后使用漏洞。(CVE-2022-48560)

  - 在处理二进制格式的畸形 Apple 属性列表文件时，Python 的 plistlib.py 中的 read_ints 通过 3.9.1 很容易因 CPU 和 RAM 耗尽而受到潜在的 DoS 攻击。(CVE-2022-48564)

  - 在 3.9.1 版本之前的 Python 中发现一个 XML External Entity (XXE) 问题。plistlib 模块不再接受 XML plist 文件中的实体声明，以避免出现 XML 漏洞。(CVE-2022-48565)

  - 在 3.9.1 及之前的 Python 中，发现 Lib/hmac.py 的 compare_digest 中存在问题。hmac.compare_digest 中的累加器变量可以实现常数时间失败优化。(CVE-2022-48566)

  - 在 3.8.18 版之前的 Python、3.9.18 版之前的 Python 3.9.x、3.10.13 版之前的 Python 3.10.x 以及 3.11.5 版之前的 Python 3.11.x 中发现一个问题。这个问题主要影响使用 TLS 客户端身份验证的服务器（如 HTTP 服务器）。如果已经创建了 TLS 服务器端套接字，则请将数据接收到套接字缓存区中，然后迅速关闭，接着您便会看到短暂出现的窗口，在此期间，SSLSocket 实例会将套接字检测为“未连接”，而且不会初始化握手，缓冲的数据仍可从套接字缓存区读取。如果服务器端 TLS 对等机预期将进行客户端证书认证，此数据就无需接受认证，此外，服务器端 TLS 对等机也无法将其与有效的 TLS 流数据区分开来。数据的大小受到缓冲区适合数量的限制。（TLS 连接无法直接用于数据泄露，因为易受攻击的代码路径要求在 SSLSocket 初始化期间关闭连接。）(CVE-2023-40217)

Tenable 已直接从 Ubuntu 安全公告中提取上述描述块。

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

The version of python27 installed on the remote host is prior to 2.7.18-2.149. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1880 advisory.

    An XML External Entity (XXE) issue was discovered in Python through 3.9.1. The plistlib module no longer     accepts entity declarations in XML plist files to avoid XML vulnerabilities. (CVE-2022-48565)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

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

  - A use-after-free exists in Python through 3.9 via heappushpop in heapq. (CVE-2022-48560)

  - An XML External Entity (XXE) issue was discovered in Python through 3.9.1. The plistlib module no longer     accepts entity declarations in XML plist files to avoid XML vulnerabilities. (CVE-2022-48565)

  - An issue was discovered in compare_digest in Lib/hmac.py in Python through 3.9.1. Constant-time-defeating     optimisations were possible in the accumulator variable in hmac.compare_digest. (CVE-2022-48566)

  - An issue was discovered in Python before 3.8.18, 3.9.x before 3.9.18, 3.10.x before 3.10.13, and 3.11.x     before 3.11.5. It primarily affects servers (such as HTTP servers) that use TLS client authentication. If     a TLS server-side socket is created, receives data into the socket buffer, and then is closed quickly,     there is a brief window where the SSLSocket instance will detect the socket as 'not connected' and won't     initiate a handshake, but buffered data will still be readable from the socket buffer. This data will not     be authenticated if the server-side TLS peer is expecting client certificate authentication, and is     indistinguishable from valid TLS stream data. Data is limited in size to the amount that will fit in the     buffer. (The TLS connection cannot directly be used for data exfiltration because the vulnerable code path     requires that the connection be closed on initialization of the SSLSocket.) (CVE-2023-40217)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the python2 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

An update of the python3 package has been released.

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3575 advisory.

    -------------------------------------------------------------------------     Debian LTS Advisory DLA-3575-1                debian-lts@lists.debian.org     https://www.debian.org/lts/security/                        Helmut Grohne     September 20, 2023                            https://wiki.debian.org/LTS
    -------------------------------------------------------------------------

    Package        : python2.7     Version        : 2.7.16-2+deb10u3     CVE ID         : CVE-2021-23336 CVE-2022-0391 CVE-2022-48560 CVE-2022-48565                      CVE-2022-48566 CVE-2023-24329 CVE-2023-40217

    This update fixes multiple vulnerabilities concerning the urlparse module as     well as vulnerabilities concerning the heapq, hmac, plistlib and ssl modules.

    CVE-2021-23336

        Python was vulnerable to Web Cache Poisoning via urlparse.parse_qsl and         urlparse.parse_qs by using a vector called parameter cloaking. When the         attacker can separate query parameters using a semicolon (;), they can         cause a difference in the interpretation of the request between the proxy         (running with default configuration) and the server. This can result in         malicious requests being cached as completely safe ones, as the proxy would         usually not see the semicolon as a separator, and therefore would not         include it in a cache key of an unkeyed parameter.

    CVE-2022-0391

        The urlparse module helps break Uniform Resource Locator (URL) strings into         components. The issue involves how the urlparse method does not sanitize         input and allows characters like '\r' and '\n' in the URL path.  This flaw         allows an attacker to input a crafted URL, leading to injection attacks.

    CVE-2022-48560

        A use-after-free exists in Python via heappushpop in heapq.

    CVE-2022-48565

        An XML External Entity (XXE) issue was discovered in Python.  The plistlib         module no longer accepts entity declarations in XML plist files to avoid         XML vulnerabilities.

    CVE-2022-48566

        An issue was discovered in compare_digest in Lib/hmac.py in Python.
        Constant-time-defeating optimisations were possible in the accumulator         variable in hmac.compare_digest.

    CVE-2023-24329

        An issue in the urlparse component of Python allows attackers to bypass         blocklisting methods by supplying a URL that starts with blank characters.

    CVE-2023-40217

        The issue primarily affects servers written in Python (such as HTTP         servers) that use TLS client authentication. If a TLS server-side socket is         created, receives data into the socket buffer, and then is closed quickly,         there is a brief window where the SSLSocket instance will detect the socket         as not connected and won't initiate a handshake, but buffered data will         still be readable from the socket buffer.  This data will not be         authenticated if the server-side TLS peer is expecting client certificate         authentication, and is indistinguishable from valid TLS stream data. Data         is limited in size to the amount that will fit in the buffer. (The TLS         connection cannot directly be used for data exfiltration because the         vulnerable code path requires that the connection be closed on         initialization of the SSLSocket.)

        A use-after-free problem was found in the heappushpop function in         the heapq module.

    CVE-2022-48564

        A potential denial-of-service vulnerability was discovered in the         read_ints function used when processing certain malformed Apple         Property List files in binary format.

    CVE-2022-48565

        An XML External Entity (XXE) issue was discovered.  In order to         avoid possible vulnerabilities, the plistlib module no longer         accepts entity declarations in XML plist files.

    CVE-2022-48566

        Possible constant-time-defeating compiler optimisations were         discovered in the accumulator variable in hmac.compare_digest.

    CVE-2023-40217

        It was discovered that it might be possible to bypass some of the         protections implemented by the TLS handshake in the ssl.SSLSocket         class.  For example, unauthenticated data might be read by a program         expecting data authenticated by client certificates.
