- Summary
- ModSecurity has possible DoS vulnerability in sanitiseArg action
- Details
-
ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. Versions prior to 2.9.10 contain a denial of service vulnerability similar to GHSA-859r-vvv8-rm8r/CVE-2025-47947. The
sanitiseArg(andsanitizeArg- this is the same action but an alias) is vulnerable to adding an excessive number of arguments, thereby leading to denial of service. Version 2.9.10 fixes the issue. As a workaround, avoid using rules that contain thesanitiseArg(orsanitizeArg) action. - Database specific
