CBL Mariner 2.0 Security Update: httpd (CVE-2025-49812)

high Nessus Plugin ID 242400

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of httpd installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-49812 advisory.

 - 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)

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

Solution

Update the affected packages.
