CVE-2024-7347: F5 Nginx Open Source

Medium severity, CVSS 4.7. EPSS: 0.3% chance of exploitation in the next 30 days.

NGINX Open Source and NGINX Plus have a vulnerability in the ngx_http_mp4_module, which might allow an attacker to over-read NGINX worker memory resulting in its termination, using a specially crafted mp4 file. The issue only affects NGINX if it is built with the ngx_http_mp4_module and the mp4 directive is used in the configuration file. Additionally, the attack is possible only if an attacker can trigger the processing of a specially crafted mp4 file with the ngx_http_mp4_module.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Affected products

• F5 Nginx Open Source: from 1.5.13, before 1.26.2 (fixed in 1.26.2); version 1.27.0 only
• F5 Nginx Plus: from r27, before r31 (fixed in r31); version r31 only; version r32 only
