Information disclosure in PAN-OS 7.1.23 and earlier, PAN-OS 8.0.18 and earlier, PAN-OS 8.1.8-h4 and earlier, and PAN-OS 9.0.2 and earlier may allow for an authenticated user with read-only privileges to extract the API key of the device and/or the username/password from the XML API (in PAN-OS) and possibly escalate privileges granted to them.

If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r (Affected 1.0.2-1.0.2q).

The PAN-OS management web interface in PAN-OS 7.1.21 and earlier, PAN-OS 8.0.14 and earlier, and PAN-OS 8.1.5 and earlier, may allow an unauthenticated attacker to inject arbitrary JavaScript or HTML.

The PAN-OS external dynamics lists in PAN-OS 7.1.21 and earlier, PAN-OS 8.0.14 and earlier, and PAN-OS 8.1.5 and earlier, may allow an attacker that is authenticated in Next Generation Firewall with write privileges to External Dynamic List configuration to inject arbitrary JavaScript or HTML.

_set_key in agent/helpers/table_container.c in Net-SNMP before 5.8 has a NULL Pointer Exception bug that can be used by an authenticated attacker to remotely cause the instance to crash via a crafted UDP packet, resulting in Denial of Service.

The PAN-OS response for GlobalProtect Gateway in Palo Alto Networks PAN-OS 6.1.21 and earlier, PAN-OS 7.1.18 and earlier, PAN-OS 8.0.11 and earlier may allow an unauthenticated attacker to inject arbitrary JavaScript or HTML. PAN-OS 8.1 is NOT affected.
