Apache 2.4.x < 2.4.59 Multiple Vulnerabilities

high Nessus Plugin ID 192923

Synopsis

The remote web server is affected by multiple vulnerabilities.

Description

The version of Apache httpd installed on the remote host is prior to 2.4.59. It is, therefore, affected by multiple vulnerabilities as referenced in the 2.4.59 advisory.

- Apache HTTP Server: HTTP Response Splitting in multiple modules: HTTP Response splitting in multiple modules in Apache HTTP Server allows an attacker that can inject malicious response headers into backend applications to cause an HTTP desynchronization attack. Users are recommended to upgrade to version 2.4.59, which fixes this issue. Acknowledgements: (CVE-2024-24795)

- Apache HTTP Server: HTTP/2 DoS by memory exhaustion on endless continuation frames: HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion.
Acknowledgements: finder: Bartek Nowotarski (https://nowotarski.info/) (CVE-2024-27316)

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

Solution

Upgrade to Apache version 2.4.59 or later.
