Palo Alto firewalls: Public exploits, rising attacks, ineffective mitigationWhile it initially seemed that protecting Palo Alto Network firewalls from attacks leveraging CVE-2024-3400 would be possible by disabling the devices' telemetry, it has now been confirmed that this mitigation is ineffectual. Geopolitical tensions escalate OT cyber attacksIn this Help Net Security interview, Andrew Ginter, VP of Industrial Security at Waterfall Security, discusses operational technology cyber attacks and their 2024 Threat Report.

Approximately 22,500 exposed Palo Alto GlobalProtect firewall devices are likely vulnerable to the CVE-2024-3400 flaw, a critical command injection vulnerability that has been actively exploited in attacks since at least March 26, 2024. CVE-2024-3400 is a critical vulnerability impacting specific Palo Alto Networks' PAN-OS versions in the GlobalProtect feature that allows unauthenticated attackers to execute commands with root privileges using command injection triggered by arbitrary file creation.

While it initially seemed that protecting Palo Alto Network firewalls from attacks leveraging CVE-2024-3400 would be possible by disabling the devices' telemetry, it has now been comfirmed that this mitigation is ineffectual."Device telemetry does not need to be enabled for PAN-OS firewalls to be exposed to attacks related to this vulnerability," Palo Alto Networks noted on Tuesday, and said they are aware of an "Increasing number of attacks that leverage the exploitation of this vulnerability."

Exploit code is now available for a maximum severity and actively exploited vulnerability in Palo Alto Networks' PAN-OS firewall software. While Palo Alto Networks has started releasing hotfixes on Monday to secure unpatched firewalls exposed to attacks, the vulnerability has been exploited in the wild as a zero-day since March 26th to backdoor firewalls using Upstyle malware, pivot to internal networks, and steal data by a threat group believed to be state-sponsored and tracked as UTA0218.

Palo Alto Networks has started releasing hotfixes for a zero-day vulnerability that has been actively exploited since March 26th to backdoor PAN-OS firewalls. This maximum severity security flaw affects PAN-OS 10.2, PAN-OS 11.0, and PAN-OS 11.1 firewalls with device telemetry and GlobalProtect enabled.

Palo Alto Networks has released hotfixes to address a maximum-severity security flaw impacting PAN-OS software that has come under active exploitation in the wild. Tracked as CVE-2024-3400 (CVSS...

Palo Alto Networks firewalls under attack, hotfixes incoming!Attackers are exploiting a command injection vulnerability affecting Palo Alto Networks' firewalls, the company has warned, and urged customers to implement temporary mitigations and get in touch to check whether their devices have been compromised. It can handle almost anything, and someone once called it the kitchen sink of PKI. Microsoft patches two actively exploited zero-daysOn this April 2024 Patch Tuesday, Microsoft has fixed a record 147 CVE-numbered vulnerabilities, including CVE-2024-29988, a vulnerability that Microsoft hasn't marked as exploited, but Peter Girnus, senior threat researcher with Trend Micro's Zero Day Initiative, has found being leveraged by attackers in the wild.
