CVE-2009-5031: Opensuse

Medium severity, CVSS 4.3. EPSS: 2.9% chance of exploitation in the next 30 days.

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.

Affected products

• Opensuse Opensuse: version 11.4 only; version 12.2 only; version 12.3 only
• Trustwave Modsecurity: before 2.5.11 (fixed in 2.5.11)
