Package : modsecurity-apache Version : 2.9.3-1+deb10u2 CVE ID : CVE-2022-48279 CVE-2023-24021 Debian Bug : 1029329

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 iverflows on the Web Application Firewall when executing rules reading the FILES_TMP_CONTENT collection.

For Debian 10 buster, these problems have been fixed in version 2.9.3-1+deb10u2.

We recommend that you upgrade your modsecurity-apache packages.
