"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0155 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2023-38709:
    Faulty input validation in the core of Apache allows malicious or exploitable backend/content generators
    to split HTTP responses.

    CVE-2024-38473:
    Encoding problem in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows request URLs with incorrect
    encoding to be sent to backend services, potentially bypassing authentication via crafted requests.
    Users are recommended to upgrade to version 2.4.60, which fixes this issue.

    CVE-2024-38474:
    Substitution encoding issue in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows attacker to
    execute scripts in
    directories permitted by the configuration but not directly reachable by anyURL or source disclosure of
    scripts meant to only to be executed as CGI.
    Users are recommended to upgrade to version 2.4.60, which fixes this issue.
    Some RewriteRules that capture and substitute unsafely will now fail unless rewrite flag UnsafeAllow3F
    is specified.

    CVE-2024-38475:
    Improper escaping of output in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to
    map URLs to filesystem locations that arepermitted to be served by the server but are not
    intentionally/directly reachable by any URL, resulting in code execution or source code disclosure.
    Substitutions inserver context that use a backreferences or variables as the first segment of the
    substitution are affected. Some unsafe RewiteRules will be broken by this change and the rewrite flag
    UnsafePrefixStat can be used to opt back in once ensuring the substitution is appropriately constrained.

    CVE-2024-38477:
    null pointer dereference in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows an attacker to crash
    the server via a malicious request.
    Users are recommended to upgrade to version 2.4.60, which fixes this issue.

    CVE-2024-39573:
    Potential SSRF in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to cause unsafe
    RewriteRules to unexpectedly setup URL's to be handled by mod_proxy.
    Users are recommended to upgrade to version 2.4.60, which fixes this issue.
