Palo Alto Networks issued a warning about a concerning exploit chain that has been targeted at its firewall management interfaces, raising red flags in the cybersecurity community. The company disclosed that attackers have been utilizing a combination of two recently exposed vulnerabilities in their PAN-OS software, putting organizations at risk of potential security breaches.
The first vulnerability, known as CVE-2025-0111, was initially revealed on February 12th, prompting Palo Alto Networks to rate it as a “highest” urgency level. The company recommended that customers take the precautionary step of disabling internet access to the PAN-OS web management interface in order to mitigate the risk of exploitation. The necessity for immediate action was underscored by an updated security advisory published a week after the initial disclosure, where Palo Alto Networks highlighted exploitation activity involving CVE-2025-0111 in conjunction with two other vulnerabilities.
One of the vulnerabilities that has been linked to the exploit chain is CVE-2025-0108, which was recently disclosed and came under attack as a zero-day vulnerability. The other vulnerability, CVE-2024-9474, had previously been disclosed and exploited in zero-day attacks against Palo Alto Networks’ firewall management interfaces in November. Despite efforts to address these vulnerabilities, some instances remain unpatched, leaving organizations vulnerable to potential threats.
Palo Alto Networks observed exploit attempts chaining CVE-2025-0108 with CVE-2024-9474 and CVE-2025-0111 on unsecured PAN-OS web management interfaces, highlighting the critical need for organizations to take immediate action to safeguard their systems. The company urged customers to patch the identified vulnerabilities in the PAN-OS web management interface to prevent unauthorized access and potential system compromise.
Security researchers Émilio Gonzalez and Maxime Gaudreault, alongside Palo Alto Networks’ own Deep Product Security Research Team, were credited with discovering and reporting CVE-2025-0111. This collaboration underscores the importance of ongoing vigilance and collaboration in identifying and addressing cybersecurity threats before they can be exploited by malicious actors.
In response to the escalating threat landscape, CISA added CVE-2025-0111 to its Known Exploited Vulnerabilities list, setting a deadline for federal agencies to implement vendor mitigations by March 13th. This heightened awareness of the vulnerabilities underscores the urgency of addressing security concerns and implementing necessary safeguards to protect critical infrastructure and sensitive data.
The recurring vulnerabilities in Palo Alto Networks’ PAN-OS software have made it an increasingly attractive target for attackers. From zero-day exploits to command injection flaws, the company has faced a series of security challenges that highlight the ongoing need for robust cybersecurity measures and proactive risk management strategies.
As organizations grapple with the evolving cybersecurity landscape, Palo Alto Networks’ experience serves as a cautionary tale of the importance of continuous monitoring, timely patching, and proactive threat intelligence to stay one step ahead of potential threats. By prioritizing cybersecurity best practices and investing in robust defense mechanisms, organizations can mitigate risks, safeguard their systems, and protect sensitive data from exploitation by threat actors.
