Description

An information exposure through log file vulnerability where sensitive fields are recorded in the configuration log without masking on Palo Alto Networks PAN-OS software when the after-change-detail custom syslog field is enabled for configuration logs and the sensitive field appears multiple times in one log entry. The first instance of the sensitive field is masked but subsequent instances are left in clear text. This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.16; PAN-OS 9.0 versions earlier than PAN-OS 9.0.10; PAN-OS 9.1 versions earlier than PAN-OS 9.1.4.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

8.1 ≤ v < 8.1.168.1.0 ≤ v ≤ 8.1.159.0 ≤ v < 9.0.109.0.0 ≤ v < 9.0.109.1 ≤ v < 9.1.49.1.0 ≤ v < 9.1.48.19.09.1
Vendor states this is fixed in 10.0.0 (unaffected)
Affected range stops below 8.1.16, so it looks safe — our inference, not a vendor statement
Affected range stops below 9.0.10, so it looks safe — our inference, not a vendor statement
Affected range stops below 9.1.4, so it looks safe — our inference, not a vendor statement
