Paloaltonetworks: >> Pan-Os >> 10.1.11 Security Vulnerabilities
A packet processing mechanism in Palo Alto Networks PAN-OS software enables a remote attacker to reboot hardware-based firewalls. Repeated attacks eventually cause the firewall to enter maintenance mode, which requires manual intervention to bring the firewall back online.
This affects the following hardware firewall models:
- PA-5400 Series firewalls
- PA-7000 Series firewalls

A weak (low bit strength) device certificate in Palo Alto Networks Panorama software enables an attacker to perform a meddler-in-the-middle (MitM) attack to capture encrypted traffic between the Panorama management server and the firewalls it manages. With sufficient computing resources, the attacker could break encrypted communication and expose sensitive information that is shared between the management server and the firewalls.

A vulnerability in the GlobalProtect Gateway in Palo Alto Networks PAN-OS software enables an authenticated attacker to impersonate another user and send network packets to internal assets. However, this vulnerability does not allow the attacker to receive response packets from those internal assets.

An improper authorization vulnerability in Palo Alto Networks Panorama software enables an authenticated read-only administrator to upload files using the web interface and completely fill one of the disk partitions with those uploaded files, which prevents the ability to log into the web interface or to download PAN-OS, WildFire, and content images.
This issue affects only the web interface of the management plane; the dataplane is unaffected.

A reflected cross-site scripting (XSS) vulnerability in the GlobalProtect portal feature of Palo Alto Networks PAN-OS software enables execution of malicious JavaScript (in the context of a user’s browser) if a user clicks on a malicious link, allowing phishing attacks that could lead to credential theft.

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.
