The recently disclosed CVE-2024-2552 represents a command injection vulnerability in Palo Alto Networks PAN-OS software. This vulnerability allows an authenticated administrator to bypass system restrictions in the management plane and delete files on the firewall. Given the critical nature of firewall functionality, this vulnerability poses a significant risk to organizations.
With a CVSS score of 6.8, this vulnerability is classified as medium severity. The attack vector is local, requiring high privileges, which means that an attacker must have existing access to the management interface. However, the potential for file deletion could lead to significant operational disruption.
Risk to organizations includes the possibility of unauthorized file deletion, which could compromise the integrity and availability of critical firewall configurations. The urgency for defenders is heightened as this vulnerability could be exploited if an attacker gains access to the management interface.
Organizations should prioritize patching immediately.
Vulnerability Details
According to the official description, this vulnerability allows an authenticated administrator to bypass system restrictions in the management plane and delete files on the firewall. The affected product is the PAN-OS from Palo Alto Networks, which is critical for managing network security.
The CVSS version 4.0 score is 6.8, indicating a medium severity level due to the potential impacts on integrity and availability. The vulnerability was published on November 14, 2024, and is categorized under CWE-22, which involves improper limitation of a pathname to a restricted directory.
Technical Analysis
The root cause of this vulnerability is a command injection flaw that occurs in the management interface of the PAN-OS software. This flaw results from improper validation of user input, allowing attackers with authenticated access to execute arbitrary commands.
The attack vector is local, meaning that an attacker must have access to the management interface. Attack complexity is low, as it does not require any specialized conditions beyond the existing access to the interface. The required privileges are high, as the attacker must be an authenticated administrator.
User interaction is not required, simplifying the exploitation process. The integrity impact is high since unauthorized file deletion could compromise the integrity of the firewall configuration. Similarly, the availability impact is also high, as deleting critical files could lead to service disruptions.
Risk & Impact Analysis
Organizations using vulnerable versions of PAN-OS face significant deployment risks. The ability for an authenticated administrator to delete files undermines the security posture of the firewall, potentially allowing for comprehensive network exploitation.
The potential blast radius includes critical systems relying on the firewall for security. The urgency assessment based on the CVSS score indicates that organizations should act swiftly to mitigate this risk. Given that this vulnerability is not currently included in the KEV catalog, immediate action is still necessary.
Organizations should address in priority patch cycle.
