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

    In some mod_ssl configurations on Apache HTTP Server versions through to 2.4.63, an HTTP desynchronisation
    attack allows a man-in-the-middle attacker to hijack an HTTP session via a TLS upgrade.

    Only configurations using 'SSLEngine optional' to enable TLS upgrades are affected. Users are recommended
    to upgrade to version 2.4.64, which removes support for TLS upgrade.(CVE-2025-49812)

    In some mod_ssl configurations on Apache HTTP Server 2.4.35 through to 2.4.63, an access control bypass by
    trusted clients is possible using TLS 1.3 session resumption.

    Configurations are affected when mod_ssl is configured for multiple virtual hosts, with each restricted to
    a different set of trusted client certificates (for example with a different SSLCACertificateFile/Path
    setting). In such a case, a client trusted to access one virtual host may be able to access another
    virtual host, if SSLStrictSNIVHostCheck is not enabled in either virtual host.(CVE-2025-23048)

    Insufficient escaping of user-supplied data in mod_ssl in Apache HTTP Server 2.4.63 and earlier allows an
    untrusted SSL/TLS client to insert escape characters into log files in some configurations.

    In a logging configuration where CustomLog is used with '%{varname}x' or '%{varname}c' to log variables
    provided by mod_ssl such as SSL_TLS_SNI, no escaping is performed by either mod_log_config or mod_ssl and
    unsanitized data provided by the client may appear in log files.(CVE-2024-47252)

    SSRF in Apache HTTP Server with mod_proxy loaded allows an attacker to send outbound proxy requests to a
    URL controlled by the attacker. Requires an unlikely configuration where mod_headers is configured to
    modify the Content-Type request or response header with a value provided in the HTTP request.

    Users are recommended to upgrade to version 2.4.64 which fixes this issue.(CVE-2024-43204)

    HTTP response splitting in the core of Apache HTTP Server allows an attacker who can manipulate the
    Content-Type response headers of applications hosted or proxied by the server can split the HTTP response.

    This vulnerability was described as CVE-2023-38709 but the patch included in Apache HTTP Server 2.4.59 did
    not address the issue.

    Users are recommended to upgrade to version 2.4.64, which fixes this issue.(CVE-2024-42516)

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