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.
