Fortinet FortiClient Link Following Local Privilege Escalation Vulnerability
Fortinet
A high-severity privilege escalation vulnerability exists in Fortinet FortiClient that allows local attackers with low-privileged code execution to escalate their access rights to higher privilege levels on affected systems. An attacker would need to already have some level of code execution capability on the target machine to exploit this flaw. Security teams should prioritize patching FortiClient installations and implement controls to restrict local code execution, while monitoring systems for signs of privilege escalation attempts.
