CVE-2025-0109 is classified as a medium-severity vulnerability with a CVSS score of 6.9. This vulnerability allows an unauthenticated attacker with network access to the management web interface of Palo Alto Networks PAN-OS to delete certain files as the “nobody” user. The affected files include limited logs and configuration files, but do not include critical system files.
Risk to organizations includes unauthorized deletion of logs and configuration files, which can hinder incident response and operational integrity. It is vital for organizations to prioritize addressing this vulnerability to protect their network infrastructure. Given that the vulnerability is currently in a deferred status, it is crucial to monitor updates from Palo Alto Networks regarding potential mitigations or patches.
Organizations should prioritize patching immediately. The publication date of this vulnerability is February 12, 2025, and it is important to remain vigilant for any developments or official advisories from the vendor.
To reduce the risk associated with this issue, Palo Alto Networks recommends restricting access to the management web interface to only trusted internal IP addresses according to their best practices deployment guidelines.
Vulnerability Details
The vulnerability described by CVE-2025-0109 enables unauthenticated file deletion within the PAN-OS management web interface. This vulnerability is categorized under CWE-73, which pertains to improper limitation of a pathname to a restricted directory ('Path Traversal'). The vulnerability has a CVSS score of 6.9, indicating a medium severity level. The attack vector is classified as NETWORK, with a low attack complexity and no privileges required for exploitation.
The specific details of the CVSS vector string for this vulnerability indicate that it poses a low integrity impact while having no confidentiality or availability impact. This means that while attackers may delete logs and configuration files, they cannot compromise the overall system functionality.
This vulnerability does not affect Cloud NGFW or Prisma Access software, limiting its impact to specific deployments of PAN-OS.
Technical Analysis
The root cause of CVE-2025-0109 stems from the improper handling of user authentication within the management web interface of PAN-OS. An attacker with network access can exploit this vulnerability to delete various files relevant to system configuration and logging as the 'nobody' user.
The attack vector is network-based, allowing remote attackers to initiate the deletion without requiring physical access to the device. The attack complexity is low, meaning that the vulnerability can be exploited easily due to the lack of required privileges or user interaction.
The confidentiality impact is rated as none, indicating that sensitive information is not exposed through this vulnerability. However, the integrity impact is low, as the attacker can manipulate log files and configuration data, potentially leading to operational disruptions.
No user interaction is required for this vulnerability to be exploited, which increases its risk profile.
Risk & Impact Analysis
Real-world deployment of PAN-OS systems without proper access controls poses a significant risk due to CVE-2025-0109. Attackers may leverage this vulnerability to delete critical logs and configuration files, which can severely hinder incident response efforts and operational integrity.
Organizations should assess their network infrastructure and ensure that access to the management web interface is strictly controlled. This includes implementing network segmentation, firewall rules, and access control lists to limit exposure only to trusted internal IP addresses.
The urgency for remediation is categorized as medium due to the potential impact of unauthorized access and file deletion. Organizations should prioritize addressing this vulnerability in their patch management cycle, particularly in environments where PAN-OS is deployed.
