NewStart CGSL CORE 5.05 / MAIN 5.05 : tomcat Multiple Vulnerabilities (NS-SA-2021-0144)

high Nessus Plugin ID 154555


The remote NewStart CGSL host is affected by multiple vulnerabilities.


The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has tomcat packages installed that are affected by multiple vulnerabilities:

- When using FORM authentication with Apache Tomcat 9.0.0.M1 to 9.0.29, 8.5.0 to 8.5.49 and 7.0.0 to 7.0.98 there was a narrow window where an attacker could perform a session fixation attack. The window was considered too narrow for an exploit to be practical but, erring on the side of caution, this issue has been treated as a security vulnerability. (CVE-2019-17563)

- The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M1 to 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service. (CVE-2020-13935)

- In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely. (CVE-2020-1935)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade the vulnerable CGSL tomcat packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
