critical Nessus Plugin ID 158196
Language:
Synopsis
The remote Debian host is missing one or more security-related updates.Description
The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2927 advisory.- 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)
- twisted is an event-driven networking engine written in Python. In affected versions twisted exposes cookies and authorization headers when following cross-origin redirects. This issue is present in the `twited.web.RedirectAgent` and `twisted.web. BrowserLikeRedirectAgent` functions. Users are advised to upgrade. There are no known workarounds. (CVE-2022-21712)
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 twisted packages.For Debian 9 stretch, these problems have been fixed in version 16.6.0-2+deb9u1.
