Описание
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 (and sanitizeArg - 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 the sanitiseArg (or sanitizeArg) action.
A denial of service flaw was found in ModSecurity. This vulnerability is present in the sanitiseArg/sanitizeArg function can be overloaded with a large number of arguments which will lead to excessive memory usage when processing json values. This may lead to a denial of service in the affected web server should memory limits be exceeded.
Отчет
User configuration must have at least one rule that does a sanitiseMatchedBytes action to be affected. Default configurations are not affected.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
