CVE-2023-25188Network attack vector

Privileged Linux access via unauthenticated diagnostic shell

Published Jun 16, 2023 · Updated Dec 12, 2024

Improper privilege management in Nokia Single RAN 19B through 21A allows attackers to gain privileged Linux access through AaShell. The root-level CCSDaemonExe service exposes AaShell on TCP port 15007 without authentication, granting access to high-privilege BTS processes and operating-system resources. Reachability requires a BTS administrator to disable the default Ethernet-port security hardening, and exploitation is limited to the internal BTS management network.
