Multiple issues were found in modsecurity-apache, open source, cross platform web application firewall (WAF) engine for Apache which allows remote attackers to bypass the applications firewall and other unspecified impact.
CVE-2022-48279
In ModSecurity before 2.9.6 and 3.x before 3.0.8, HTTP multipart
requests were incorrectly parsed and could bypass the Web Application
Firewall.
NOTE: this is related to CVE-2022-39956 but can be considered
independent changes to the ModSecurity (C language) codebase.
CVE-2023-24021
Incorrect handling of null-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 reading the FILES_TMP_CONTENT collection.
For Debian 9 stretch, these problems have been fixed in version 2.9.1-2+deb9u2.
We recommend that you upgrade your modsecurity-apache packages.
