NewStart CGSL MAIN 7.02 : libsoup3 Vulnerability (NS-SA-2026-0089)

high Nessus Plugin ID 343564

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 7.02, has libsoup3 packages installed that are affected by a vulnerability:

- A flaw was found in the cookie date handling logic of the libsoup HTTP library, widely used by GNOME and other applications for web communication. When processing cookies with specially crafted expiration dates, the library may perform an out-of-bounds memory read. This flaw could result in unintended disclosure of memory contents, potentially exposing sensitive information from the process using libsoup.
(CVE-2025-11021)

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 libsoup3 packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
