NewStart CGSL MAIN 7.02 : libblockdev Vulnerability (NS-SA-2025-0117)

high Nessus Plugin ID 242796

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

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

 - A Local Privilege Escalation (LPE) vulnerability was found in libblockdev. Generally, the allow_active setting in Polkit permits a physically present user to take certain actions based on the session type. Due to the way libblockdev interacts with the udisks daemon, an allow_active user on a system may be able escalate to full root privileges on the target host. Normally, udisks mounts user-provided filesystem images with security flags like nosuid and nodev to prevent privilege escalation. However, a local attacker can create a specially crafted XFS image containing a SUID-root shell, then trick udisks into resizing it. This mounts their malicious filesystem with root privileges, allowing them to execute their SUID-root shell and gain complete control of the system. (CVE-2025-6019)

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