Vulnerability Details
The official description of CVE-2025-0105 states that it is an arbitrary file deletion vulnerability in Palo Alto Networks Expedition. This vulnerability allows unauthenticated attackers to delete arbitrary files accessible to the www-data user on the host filesystem. The CVSS score associated with this vulnerability is 6.9, indicating medium severity, while the CVSS v3.1 score is significantly higher at 9.1, which classifies it as critical due to the high integrity and availability impacts.
The affected product is Palo Alto Networks Expedition, specifically any versions prior to 1.2.101. The vulnerability was published on January 11, 2025, and has been classified under CWE-73, which pertains to improper handling of filenames.
Technical Analysis
The root cause of this vulnerability lies in the improper validation of file deletion requests. Attackers may leverage this flaw by sending crafted requests that target files on the filesystem, allowing them to delete files accessible to the www-data user. The attack vector is network-based, and the attack complexity is low, meaning that no specialized knowledge or extensive resources are required to exploit this vulnerability.
No privileges are required to exploit this vulnerability, and user interaction is also not necessary. The potential impacts include low integrity loss, as files can be deleted, while confidentiality and availability impacts are minimal.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-0105 is significant, especially for organizations that rely on Palo Alto Networks Expedition for critical operations. Attackers could exploit this vulnerability to delete essential files, leading to service disruptions or data loss. The blast radius can be extensive, as the vulnerability affects all versions of Expedition prior to the patch, putting numerous organizations at risk.
Given the CVSS score of 9.1 in the v3.1 classification, the urgency for remediation is high. Organizations should prioritize patching this vulnerability to prevent unauthorized access and potential exploitation. The EPSS score of 0.04368 indicates a relatively low probability of exploitation, but the potential impact remains high. Therefore, organizations must take proactive measures to mitigate any risks.
