An update for mod_security is now available for openEuler-22.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2025-1561 Final 1.0 1.0 2025-05-30 Initial 2025-05-30 2025-05-30 openEuler SA Tool V1.0 2025-05-30 mod_security security update An update for mod_security is now available for openEuler-22.03-LTS-SP4 This software is also called Modsec,it is an open-source web application firewall. It is designed for Apache HTTP Server.ModSecurity is commonly deployed to provide protections against generic classed of vulnerabilities.The install of this package is easy and you can read the README.TXT for more information. Security Fix(es): The OWASP ModSecurity Core Rule Set (CRS) is affected by a partial rule set bypass for HTTP multipart requests by submitting a payload that uses a character encoding scheme via the Content-Type or the deprecated Content-Transfer-Encoding multipart MIME header fields that will not be decoded and inspected by the web application firewall engine and the rule set. The multipart payload will therefore bypass detection. A vulnerable backend that supports these encoding schemes can potentially be exploited. The legacy CRS versions 3.0.x and 3.1.x are affected, as well as the currently supported versions 3.2.1 and 3.3.2. Integrators and users are advised upgrade to 3.2.2 and 3.3.3 respectively. The mitigation against these vulnerabilities depends on the installation of the latest ModSecurity version (v2.9.6 / v3.0.8).(CVE-2022-39956) 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.(CVE-2025-47947) An update for mod_security is now available for openEuler-22.03-LTS-SP4. openEuler Security has rated this update as having a security impact of critical.
