EulerOS Virtualization for ARM 64 3.0.6.0 : python2 (EulerOS-SA-2021-2022)
medium Nessus Plugin ID 151181
Synopsis
The remote EulerOS Virtualization for ARM 64 host is missing a security update.Description
According to the version of the python2 packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :- The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before 3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server. This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter.(CVE-2021-23336)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
