Technical details

A spoofing vulnerability exists in the Palo Alto Networks Terminal Services (TS) Agent. The TS Agent is responsible for mapping IP addresses and port ranges to specific user identities in environments like Citrix or Microsoft Terminal Services. Due to an unspecified flaw, an attacker can spoof the identity of another authenticated user. The vulnerability is network-reachable and requires no prior privileges or user interaction. Successful exploitation allows an attacker to bypass identity-based security policies or frame other users for malicious activity. The issue is resolved in Terminal Services Agent version 7.0.7.
