Multiple Vulnerabilities Found in Apache Tomcat, Four Rated Critical by CISA
Apache Tomcat has received updates addressing 11 vulnerabilities across versions 11.0.25, 10.1.59, and 9.0.121. The Apache Software Foundation rated four issues as Important, while CISA assigned Critical severity to four CVEs based on CVSS v3.1 scores reaching 9.8. The flaws include authentication bypasses, access control evasion due to path evaluation order, off-by-one errors, and HTTP/2 resource leaks leading to denial of service. One vulnerability was disclosed earlier in July, with the remaining ten detailed on August 25. Moderate and Low severity issues were also patched in the same releases. The discrepancies in severity ratings between the vendor and CISA highlight differing risk assessments for the same CVEs.
