CVE-2016-8735 is a critical-severity (CVSS 9.8) vulnerability in Apache Tomcat. CISA added it to the Known Exploited Vulnerabilities catalog on May 12, 2023, which means exploitation in the wild has been confirmed; US federal agencies had to remediate it by June 2, 2023. CISA does not currently list it as used in ransomware campaigns. Apache has 41 vulnerabilities in the KEV catalog, 8 of them linked to ransomware.
All 41 known-exploited Apache vulnerabilities →Description
Remote code execution is possible with Apache Tomcat before 6.0.48, 7.x before 7.0.73, 8.x before 8.0.39, 8.5.x before 8.5.7, and 9.x before 9.0.0.M12 if JmxRemoteLifecycleListener is used and an attacker can reach JMX ports. The issue exists because this listener wasn't updated for consistency with the CVE-2016-3427 Oracle patch that affected credential types.
