New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Apache Tomcat server is affected by multiple vulnerabilities
DescriptionThe version of Tomcat installed on the remote host is 8.5.x prior to 8.5.57. It is, therefore, affected by multiple vulnerabilities as referenced in the Fixed in Apache Tomcat 8.5.57 security advisory.
- The payload length in a WebSocket frame was not correctly validated. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service (DoS).
- An h2c direct connection did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests were made, an OutOfMemoryException could occur leading to a denial of service (DoS). (CVE-2020-13934)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to Apache Tomcat version 8.5.57 or later.
