RELATED Palo Alto firewall software vulnerability quartet revealed

“Publicly available exploit code does not exist at this time,” Randori said. The exploit developed by Randori involves chaining together a method for bypassing validations made by an external web server (HTTP smuggling) and a stack-based buffer overflow (a memory corruption issue).īoth physical and virtual firewall products running the affected software are vulnerable. Only PAN-OS firewall configurations with a GlobalProtect portal or gateway enabled are at risk, providing they are still on the older but still widely used PAN-OS 8.1 branch. PAN-OS 8.1.17 and all later PAN-OS versions resolve the risk. “This issue enables an unauthenticated network-based attacker with access to a GlobalProtect interface to execute arbitrary code with root user privileges,” it warns. Palo Alto confirms that the flaw presents an unauthenticated RCE risk.
The attacker must have network access to the GlobalProtect interface to exploit this issue. It reads:Ī memory corruption vulnerability exists in Palo Alto Networks GlobalProtect portal and gateway interfaces that enables an unauthenticated network-based attacker to disrupt system processes and potentially execute arbitrary code with root privileges. Palo Alto’s advisory on Wednesday (November 10) acknowledges that some versions its firewall products are vulnerable while stating that’s there no evidence of attacker exploitation. Randori reported the issue to Palo Alto, which released patches earlier this week. “Once an attacker has control over the firewall, they will have visibility into the internal network and can proceed to move laterally.” GlobalProtect “If an attacker successfully exploits this vulnerability they gain a shell on the affected target, access sensitive configuration data, extract credentials, and more,” the researchers said. Randori has since developed a working exploit that illustrates the scope for potential mischief. The security flaw was discovered by Randori, a red team-focused security consultancy, a year ago.
10.0, and 10.1 are immune but that still leaves thousands of older, internet-exposed systems open to attack.Ĭatch up with the latest network security news Systems running PAN-OS versions 9.0, 9.1. The vulnerability (CVE 2021-3064 with a ‘critical’ CVSS score of 9.8) allows for unauthenticated remote code execution (RCE) on multiple versions of PAN-OS 8.1 prior to 8.1.17. Security researchers have discovered a high-impact vulnerability on some versions of the widely used Palo Alto GlobalProtect Firewall/VPN that leaves enterprise networks open to attack. Details withheld about dangerous threat as orgs given one-month patching window
