NewStart CGSL CORE 5.04 / MAIN 5.04 : python-twisted-web Multiple Vulnerabilities (NS-SA-2020-0078)

critical Nessus Plugin ID 144086

Language:

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has python-twisted-web packages installed that are affected by multiple vulnerabilities:

 - In Twisted before 19.2.1, twisted.web did not validate or sanitize URIs or HTTP methods, allowing an attacker to inject invalid characters such as CRLF. (CVE-2019-12387)

 - In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request. (CVE-2020-10108)

 - In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with a content-length and a chunked encoding header, the content-length took precedence and the remainder of the request body was interpreted as a pipelined request. (CVE-2020-10109)

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

Solution

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