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).

Palo Alto Networks PAN-OS 6.1, 7.1, and 8.0.x before 8.0.7, when an interface implements SSL decryption with RSA enabled or hosts a GlobalProtect portal or gateway, might allow remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka a ROBOT attack.

XML external entity (XXE) vulnerability in the GlobalProtect internal and external gateway interface in Palo Alto Networks PAN-OS before 6.1.18, 7.0.x before 7.0.17, 7.1.x before 7.1.12, and 8.0.x before 8.0.3 allows remote attackers to obtain sensitive information, cause a denial of service, or conduct server-side request forgery (SSRF) attacks via unspecified vectors.

Cross-site scripting (XSS) vulnerability in the GlobalProtect internal and external gateway interface in Palo Alto Networks PAN-OS before 6.1.18, 7.0.x before 7.0.17, 7.1.x before 7.1.12, and 8.0.x before 8.0.3 allows remote attackers to inject arbitrary web script or HTML via vectors related to improper request parameter validation.

The DNS Proxy in Palo Alto Networks PAN-OS before 6.1.18, 7.x before 7.0.16, 7.1.x before 7.1.11, and 8.x before 8.0.3 allows remote attackers to execute arbitrary code via a crafted domain name.

Cross-site scripting (XSS) vulnerability in the management web interface in Palo Alto Networks PAN-OS before 6.1.18, 7.x before 7.0.16, 7.1.x before 7.1.11, and 8.x before 8.0.3 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Cross-site scripting (XSS) vulnerability in the GlobalProtect external interface in Palo Alto Networks PAN-OS before 6.1.18, 7.x before 7.0.16, 7.1.x before 7.1.11, and 8.x before 8.0.3 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The GlobalProtect external interface in Palo Alto Networks PAN-OS before 6.1.17, 7.x before 7.0.15, 7.1.x before 7.1.9, and 8.x before 8.0.2 provides different error messages for failed login attempts depending on whether the username exists, which allows remote attackers to enumerate account names and conduct brute-force attacks via a series of requests, aka PAN-SA-2017-0014 and PAN-72769.
