The U.S. Cybersecurity and Infrastructure Security Agency (CISA) is warning that foreign hackers are likely to exploit a newly disclosed, critical vulnerability in a raft of Palo Alto Networks firewalls and enterprise VPN appliances, which allows for device takeover without authentication. The Department of Defense (DoD) arm that oversees cyberspace operations has advised all devices affected by the flaw, CVE-2020-2021, be patched immediately. The vulnerability affects devices that use Security Assertion Markup Language (SAML), according to a tweet by the agency. “Foreign APTs will likely attempt exploit soon,” U.S. Cyber Command tweeted. “We appreciate @PaloAltoNtwks’ proactive response to this vulnerability.” Palo Alto Networks on Monday posted an advisory on the vulnerability, which affects the devices’ operating systems (PAN-OS). PAN-OS 9.1 versions earlier than PAN-OS 9.1.3; PAN-OS 9.0 versions earlier than PAN-OS 9.0.9; PAN-OS 8.1 versions earlier than PAN-OS 8.1.15, and all versions of PAN-OS 8.0 (EOL). PAN-OS 7.1 is not affected. Palo Alto already has patched the issue in PAN-OS 8.1.15, PAN-OS 9.0.9, PAN-OS 9.1.3, and all later versions, which is why CISA is urging immediate update to affected devices. The vulnerability basically allows for authentication bypass, so threat actors can access the device without having to provide any credentials. However, hackers can only exploit the flaw when SAML authentication is enabled and the “Validate Identity Provider…
