NewStart CGSL MAIN 6.06 : brotli Vulnerability (NS-SA-2023-0099)

medium Nessus Plugin ID 187350

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 6.06, has brotli packages installed that are affected by a vulnerability:

- A buffer overflow exists in the Brotli library versions prior to 1.0.8 where an attacker controlling the input length of a one-shot decompression request to a script can trigger a crash, which happens when copying over chunks of data larger than 2 GiB. It is recommended to update your Brotli library to 1.0.8 or later. If one cannot update, we recommend to use the streaming API as opposed to the one-shot API, and impose chunk size limits. (CVE-2020-8927)

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 brotli packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
