CWE-338

Description

A cryptographically weak pseudo-random number generator (PRNG) is used during authentication to the Palo Alto Networks PAN-OS web interface. This enables an authenticated attacker, with the capability to observe their own authentication secrets over a long duration on the PAN-OS appliance, to impersonate another authenticated web interface administrator's session. This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.19; PAN-OS 9.0 versions earlier than PAN-OS 9.0.14; PAN-OS 9.1 versions earlier than PAN-OS 9.1.10; PAN-OS 10.0 versions earlier than PAN-OS 10.0.4. PAN-OS 10.1 versions are not impacted.

Affected configurations

• paloaltonetworks pan-os (>= 8.1.0 < 8.1.19) • paloaltonetworks pan-os (>= 9.0.0 < 9.0.14) • paloaltonetworks pan-os (>= 9.1.0 < 9.1.10) • paloaltonetworks pan-os (>= 10.0.0 < 10.0.4)
