CVE Catalog

CVE-2017-14609

High
Published: Translated: NVD NIST

Summary

The server daemons in Kannel 1.5.0 and earlier create a PID file after dropping privileges to a non-root account. This might allow local users to kill arbitrary processes by modifying this PID file before a root script executes a 'kill' command.

Risk Assessment

The organization may be exposed to attacks from local users who can gain control over system processes, potentially leading to service disruptions.

Recommendation

It is recommended to update Kannel to the latest version to mitigate this vulnerability and to restrict access to the non-root account that can modify the PID file.

Original NVD description (English source)

The server daemons in Kannel 1.5.0 and earlier create a PID file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for PID file modification before a root script executes a "kill `cat /pathname`" command, as demonstrated by bearerbox.
