NVD Description

Note: Versions mentioned in the description apply only to the upstream apache2-mod_security2 package and not the apache2-mod_security2 package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

Incorrect handling of '\0' bytes in file uploads in ModSecurity before 2.9.7 may allow for Web Application Firewall bypasses and buffer over-reads on the Web Application Firewall when executing rules that read the FILES_TMP_CONTENT collection.
