AI Analysis
Technical Summary
This advisory covers seven security vulnerabilities in Apache Tomcat and Apache Commons FileUpload as packaged in Red Hat Enterprise Linux 8. The issues include denial of service vulnerabilities (CVE-2025-48988, CVE-2025-48989, CVE-2025-52520, CVE-2025-52434, CVE-2025-53506, CVE-2025-48976) and a security constraint bypass (CVE-2025-49125). The vulnerabilities can be triggered via multipart uploads, HTTP/2 control frames, and part headers, potentially causing service disruption or bypassing security constraints. Red Hat has issued an important security update (RHSA-2025:14177) that addresses these vulnerabilities in Apache Tomcat versions prior to 8.10.6 on Red Hat Enterprise Linux 8.
Potential Impact
The vulnerabilities primarily enable denial of service attacks against Apache Tomcat servers, potentially disrupting service availability. One vulnerability allows bypassing security constraints, which could lead to unauthorized access to protected resources. These issues affect Red Hat Enterprise Linux 8 systems running affected versions of Apache Tomcat and Apache Commons FileUpload, potentially impacting applications relying on these components.
Mitigation Recommendations
Red Hat has released an official security update (RHSA-2025:14177) that patches the affected Apache Tomcat and Apache Commons FileUpload components. Users should apply the update to versions 8.10.6 or later to remediate these vulnerabilities. Detailed update instructions are available at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official patches.
