Palo Alto Firewalls Under Attack As Miscreants Chain Flaws For Root Access

A recently patched Palo Alto Networks vulnerability (CVE-2025-0108) is being actively exploited alongside two older flaws (CVE-2024-9474 and CVE-2025-0111), allowing attackers to gain root access to unpatched firewalls. The Register reports: This story starts with CVE-2024-9474, a 6.9-rated privilege escalation vulnerability in Palo Alto Networks PAN-OS software that allowed an OS administrator with access to the management web interface to perform actions on the firewall with root privileges. The company patched it in November 2024. Dark web intelligence services vendor Searchlight Cyber's Assetnote team investigated the patch for CVE-2024-9474 and found another authentication bypass.

Palo Alto (PAN) last week fixed that problem, CVE-2025-0108, and rated it a highest urgency patch as the 8.8/10 flaw addressed an access control issue in PAN-OS's web management interface that allowed an unauthenticated attacker with network access to the management web interface to bypass authentication 'and invoke certain PHP scripts.' Those scripts could 'negatively impact integrity and confidentiality of PAN-OS.'

The third flaw is CVE-2025-0111 a 7.1-rated mess also patched last week to stop authenticated attackers with network access to PAN-OS machines using their web interface to read files accessible to the 'nobody' user. On Tuesday, US time, Palo A lot updated its advisory for CVE-2025-0108 with news that it's observed exploit attempts chaining CVE-2024-9474 and CVE-2025-0111 on unpatched and unsecured PAN-OS web management interfaces. The vendor's not explained how the three flaws are chained but we understand doing so allows an attacker to gain more powerful privileges and gain full root access to the firewall. PAN is urging users to upgrade their PAN-OS operating systems to versions 10.1, 10.2, 11.0, 11.1, and 11.2. A general hotfix is expected by Thursday or sooner, notes the Register.
