Exploits Discovered - Published CVE-2017-14681

Security News - Sep 21, 2017

Title: P3Scan privilege escalation via PID file manipulation
Author: Michael Orlitzky
Fixedin:

Summary

The p3scan daemon creates its PID file after dropping privileges to a non-root user. That may be exploited (through init scripts or other management tools) by the unprivileged user to kill root processes, since when the daemon is stopped, root usually sends a SIGTERM to the contents of the PID file (which are under the control of the runtime user). P3Scan itself ships two init scripts vulnerable to this attack.
