NewStart CGSL MAIN 7.02 : python-idna Vulnerability (NS-SA-2025-0144)

medium Nessus Plugin ID 242697

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 7.02, has python-idna packages installed that are affected by a vulnerability:

 - A vulnerability was identified in the kjd/idna library, specifically within the `idna.encode()` function, affecting version 3.6. The issue arises from the function's handling of crafted input strings, which can lead to quadratic complexity and consequently, a denial of service condition. This vulnerability is triggered by a crafted input that causes the `idna.encode()` function to process the input with considerable computational load, significantly increasing the processing time in a quadratic manner relative to the input size. (CVE-2024-3651)

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

Solution

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