An information exposure vulnerability exists in Palo Alto Networks PAN-OS software that enables a GlobalProtect end user to learn both the configured GlobalProtect uninstall password and the configured disable or disconnect passcode. After the password or passcode is known, end users can uninstall, disable, or disconnect GlobalProtect even if the GlobalProtect app configuration would not normally permit them to do so.

A cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS software enables a malicious authenticated read-write administrator to store a JavaScript payload using the web interface on Panorama appliances. This enables the impersonation of another authenticated administrator.

An arbitrary file upload vulnerability in Palo Alto Networks PAN-OS software enables an authenticated read-write administrator with access to the web interface to disrupt system processes and potentially execute arbitrary code with limited privileges on the firewall.

A DOM-Based cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS software enables a remote attacker to execute a JavaScript payload in the context of an administrator’s browser when they view a specifically crafted link to the PAN-OS web interface.

A cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS software enables a malicious authenticated read-write administrator to store a JavaScript payload using the web interface. Then, when viewed by a properly authenticated administrator, the JavaScript payload executes and disguises all associated actions as performed by that unsuspecting authenticated administrator.

A reflected cross-site scripting (XSS) vulnerability in the Captive Portal feature of Palo Alto Networks PAN-OS software can allow a JavaScript payload to be executed in the context of an authenticated Captive Portal user’s browser when they click on a specifically crafted link.

A file disclosure vulnerability in Palo Alto Networks PAN-OS software enables an authenticated read-write administrator with access to the web interface to export local files from the firewall through a race condition.

A cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS software on Panorama appliances enables an authenticated read-write administrator to store a JavaScript payload in the web interface that will execute in the context of another administrator’s browser when viewed.

When SSL/TLS Forward Proxy Decryption mode has been configured to decrypt the web transactions, the PAN-OS URL filtering feature inspects the HTTP Host and URL path headers for policy enforcement on the decrypted HTTPS web transactions but does not consider Server Name Indication (SNI) field within the TLS Client Hello handshake. This allows a compromised host in a protected network to evade any security policy that uses URL filtering on a firewall configured with SSL Decryption in the Forward Proxy mode. A malicious actor can then use this technique to evade detection of communication on the TLS handshake phase between a compromised host and a remote malicious server. This technique does not increase the risk of a host being compromised in the network. It does not impact the confidentiality or availability of a firewall. This is considered to have a low impact on the integrity of the firewall because the firewall fails to enforce a policy on certain traffic that should have been blocked. This issue does not impact the URL filtering policy enforcement on clear text or encrypted web transactions. This technique can be used only after a malicious actor has compromised a host in the protected network and the TLS/SSL Decryption feature is enabled for the traffic that the attacker controls. Palo Alto Networks is not aware of any malware that uses this technique to exfiltrate data. This issue is applicable to all current versions of PAN-OS. This issue does not impact Panorama or WF-500 appliances.
