Local Privilege escalation allows a low-privileged user to gain SYSTEM privileges in Citrix Secure Access Client for Windows

A vulnerability has been discovered in the Citrix Secure Access client for Windows which, if exploited, could allow an attacker with access to an endpoint with Standard User Account that has the vulnerable client installed to escalate their local privileges to that of NT AUTHORITY\SYSTEM.

DHCP can add routes to a client’s routing table via the classless static route option (121). VPN-based security solutions that rely on routes to redirect traffic can be forced to leak traffic over the physical interface. An attacker on the same local network can read, disrupt, or possibly modify network traffic that was expected to be protected by the VPN.
