ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. Versions up to and including 2.9.8 are vulnerable to denial of service in one special case (in stable released versions): when the payload's content type is application/json, and there is at least one rule which does a sanitiseMatchedBytes action. A patch is available at pull request 3389 and expected to be part of version 2.9.9. No known workarounds are available.
A flaw was found in the mod_security2 Apache2 module. Versions up to and including 2.9.8 are vulnerable to denial of service in one special case. In stable released versions, when the payload's content type is application/json, at least one rule performs a sanitiseMatchedBytes action, a security control that automatically cleans or neutralizes specific patterns of potentially harmful data that prevents malicious input from reaching systems or sensitive information from leaking.
