CVE-2020-2002

An authentication bypass by spoofing vulnerability exists in the authentication daemon and User-ID components of Palo Alto Networks PAN-OS by failing to verify the integrity of the Kerberos key distribution center (KDC) before authenticating users. This affects all forms of authentication that use a Kerberos authentication profile. A man-in-the-middle type of attacker with the ability to intercept communication between PAN-OS and KDC can login to PAN-OS as an administrator. This issue affects: PAN-OS 7.1 versions earlier than 7.1.26; PAN-OS 8.1 versions earlier than 8.1.13; PAN-OS 9.0 versions earlier than 9.0.6; All version of PAN-OS 8.0.
