Detailsinfo

A vulnerability classified as problematic was found in Palo Alto Cloud NGFW, PAN-OS and Prisma Access (version now known). This vulnerability affects some unknown processing of the component Packet Capture Feature. The manipulation with an unknown input leads to a cleartext storage vulnerability. The CWE definition for the vulnerability is CWE-312. The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere. As an impact it is known to affect confidentiality. CVE summarizes:

A vulnerability in the Palo Alto Networks PAN-OS® software enables unlicensed administrators to view clear-text data captured using the packet capture feature https://docs.paloaltonetworks.com/pan-os/11-0/pan-os-admin/monitoring/take-packet-captures/take-a-custom-packet-capture in decrypted HTTP/2 data streams traversing network interfaces on the firewall. HTTP/1.1 data streams are not impacted. In normal conditions, decrypted packet captures are available to firewall administrators after they obtain and install a free Decryption Port Mirror license. The license requirement ensures that this feature can only be used after approved personnel purposefully activate the license. For more information, review how to configure decryption port mirroring https://docs.paloaltonetworks.com/network-security/decryption/administration/monitoring-decryption/configure-decryption-port-mirroring . The administrator must obtain network access to the management interface (web, SSH, console, or telnet) and successfully authenticate to exploit this issue. Risk of this issue can be greatly reduced by restricting access to the management interface to only trusted administrators and from only internal IP addresses according to our recommended critical deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 . Customer firewall administrators do not have access to the packet capture feature in Cloud NGFW. This feature is available only to authorized Palo Alto Networks personnel permitted to perform troubleshooting. Prisma® Access is not impacted by this vulnerability.
