An improper file signature check in Palo Alto Networks Cortex XDR agent may allow an attacker to bypass the Cortex XDR agent's executable blocking capabilities and run untrusted executables on the device. This issue can be leveraged to execute untrusted software without being detected or blocked.


Palo Alto Networks thanks the Cyber Defence Center of BITMARCK, and especially Maximilan Pappert for discovering and reporting this issue.
