CVE-2009-5031

Publication date 22 July 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

ModSecurity before 2.5.11 treats request parameter values containing single quotes as files, which allows remote attackers to bypass filtering rules and perform other attacks such as cross-site scripting (XSS) attacks via a single quote in a request parameter in the Content-Disposition field of a request with a multipart/form-data Content-Type header.
