But this week "thousands of Palo Alto Networks firewalls were compromised by attackers exploiting two recently patched security bug," reports the Register:
The intruders were able to deploy web-accessible backdoors to remotely control the equipment as well as cryptocurrency miners and other malware. Roughly 2,000 devices had been hijacked as of Wednesday — a day after Palo Alto Networks pushed a patch for the holes — according to Shadowserver and Onyphe. As of Thursday, the number of seemingly compromised devices had dropped to about 800. The vendor, however, continues to talk only of a "limited number" of exploited installations... The Register has asked for clarification, including how many compromised devices Palo Alto Networks is aware of, and will update this story if and when we hear back from the vendor.
Rumors started swirling last week about a critical security hole in Palo Alto Networks appliances that allowed remote unauthenticated attackers to execute arbitrary code on devices. Exploitation requires access to the PAN-OS management interface, either across the internet or via an internal network. The manufacturer did eventually admit that the firewall-busting vulnerability existed, and had been exploited as a zero-day — but it was still working on a patch. On Tuesday, PAN issued a fix, and at that time said there were actually two vulnerabilities. The first is a critical (9.3 CVSS) authentication bypass flaw tracked as CVE-2024-0012. The second, a medium-severity (6.9 CVSS) privilege escalation bug tracked as CVE-2024-9474. The two can be chained together to allow remote code execution (RCE) against the PAN-OS management interface... once the attackers break in, they are using this access to deploy web shells, Sliver implants, and/or crypto miners, according to Wiz threat researchers.
