Mandriva Linux Security Advisory : apache-mod_security (MDVSA-2012:182)
Medium Nessus Plugin ID 63331
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionMultiple vulnerabilities has been discovered and corrected in apache-mod_security :
ModSecurity before 2.6.6, when used with PHP, does not properly handle single quotes not at the beginning of a request parameter value in the Content-Disposition field of a request with a multipart/form-data Content-Type header, which allows remote attackers to bypass filtering rules and perform other attacks such as cross-site scripting (XSS) attacks. NOTE: this vulnerability exists because of an incomplete fix for CVE-2009-5031 (CVE-2012-2751).
ModSecurity <= 2.6.8 is vulnerable to multipart/invalid part ruleset bypass, this was fixed in 2.7.0 (released on2012-10-16) (CVE-2012-4528).
The updated packages have been patched to correct these issues.
SolutionUpdate the affected apache-mod_security and / or mlogc packages.
