Name of the Vulnerable Software and Affected Versions CoreDial sipXcom versions up to and including 21.04

Description The issue is related to insecure permissions, allowing a user with the ability to run commands as the daemon user on a sipXcom server to overwrite a service file and escalate their privileges to root. This is due to incorrect assignment of privileges. Exploitation of this issue may allow an attacker to elevate their privileges or execute arbitrary commands.
