CVE-2021-3048palo alto networkspan-os+1
EPSS score0.84%
Certain invalid URL entries contained in an External Dynamic List (EDL) cause the Device Server daemon (devsrvr) to stop responding. This condition causes subsequent commits on the firewall to fail and prevents administrators from performing commits and configuration changes even though the firewall remains otherwise functional. If the firewall then restarts, it results in a denial-of-service (DoS) condition and the firewall stops processing traffic. This issue impacts: PAN-OS 9.0 versions earlier than PAN-OS 9.0.14; PAN-OS 9.1 versions earlier than PAN-OS 9.1.9; PAN-OS 10.0 versions earlier than PAN-OS 10.0.5. PAN-OS 8.1 and PAN-OS 10.1 versions are not impacted.CVE-2021-3052palo alto networkspan-os+1EPSS score0.63%
A reflected cross-site scripting (XSS) vulnerability in the Palo Alto Network PAN-OS web interface enables an authenticated network-based attacker to mislead another authenticated PAN-OS administrator to click on a specially crafted link that performs arbitrary actions in the PAN-OS web interface as the targeted authenticated administrator. This issue impacts: PAN-OS 8.1 versions earlier than 8.1.20; PAN-OS 9.0 versions earlier than 9.0.14; PAN-OS 9.1 versions earlier than 9.1.10; PAN-OS 10.0 versions earlier than 10.0.2.
