AI Analysis
Technical Summary
The vulnerability identified as CVE-2026-29129 in Apache Tomcat involves the failure to preserve the configured cipher preference order in affected versions. This means that the server may not enforce the administrator's specified order of cipher suites during TLS negotiation, potentially allowing weaker ciphers to be selected over stronger ones. The affected versions include 11.0.16 through 11.0.18, 10.1.51 through 10.1.52, and 9.0.114 through 9.0.115. The Apache Software Foundation has released fixed versions 11.0.20, 10.1.53, and 9.0.116 to resolve this issue.
Potential Impact
The impact of this vulnerability is that the intended cipher suite preference order is not enforced, which could lead to the use of less secure cipher suites during TLS connections. This may weaken the security posture of affected Apache Tomcat servers by potentially allowing connections with weaker encryption. There are no known exploits in the wild at this time.
Mitigation Recommendations
Users should upgrade affected Apache Tomcat versions to 11.0.20, 10.1.53, or 9.0.116 as recommended by the Apache Software Foundation. This upgrade addresses the issue by preserving the configured cipher preference order. No other mitigation steps are indicated.
