Description
In ModSecurity before 2.9.7, FILES_TMP_CONTENT sometimes lacked the complete content. This can lead to a Web Application Firewall bypass.
Incorrect handling of '\0' bytes in file uploads in ModSecurity before 2.9.7 may allow for Web Application Firewall bypasses and buffer overflows on the Web Application Firewall when executing rules that read the FILES_TMP_CONTENT collection.
