"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.(CVE-2024-43204)

Tenable has extracted the preceding description block directly from the EulerOS httpd security advisory.

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