Apache 2.4.x < 2.4.71 Multiple Vulnerabilities

critical Web App Scanning Plugin ID 115821

Synopsis

Apache 2.4.x < 2.4.71 Multiple Vulnerabilities

Description

According to its banner, the version of Apache httpd installed on the remote host is prior to 2.4.71. It is, therefore, affected by multiple vulnerabilities:

 - A concurrent execution using shared resource with improper synchronization vulnerability in mod_http2 in assign_headers() can lead to heap corruption and remote code execution. This issue affects Apache HTTP Server from 2.4.55 through 2.4.70. (CVE-2026-119618)

 - A NULL pointer dereference vulnerability in mod_md during HTTP request processing allows a remote attacker to crash a child process. This issue affects Apache HTTP Server from 2.4.30 through 2.4.70. (CVE-2026-106023)

 - A 1 byte stack-based buffer overflow vulnerability exists in mod_vhost_alias, introduced by the fix for CVE-2026-63292. This issue affects Apache HTTP Server 2.4.69 and 2.4.70. (CVE-2026-109163)

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

Solution

Upgrade to Apache version 2.4.71 or later.
