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.

Security readout for executives and security teams

Older ModSecurity versions can misunderstand certain uploaded form fields and let malicious input evade WAF filtering. The main business risk is false confidence: applications may appear protected while attack traffic reaches them, including XSS attempts. Exposure is most likely on legacy web servers or distribution packages running ModSecurity before 2.5.11, especially where multipart form submissions are accepted and WAF rules are relied on to block application-layer attacks. Prioritize remediation for internet-facing applications that accept file uploads or forms and depend on ModSecurity for attack filtering. Risk is lower where systems are modern, patched, or have strong application-side validation. Mitigation focus: Inventory ModSecurity versions across web servers and appliances.; Upgrade ModSecurity to 2.5.11 or a vendor-fixed package.; Review openSUSE or distribution advisories for backported fixes..
