CVE-2025-0104 is a high-severity reflected cross-site scripting (XSS) vulnerability found in Palo Alto Networks Expedition. This vulnerability allows attackers to execute malicious JavaScript code in the context of an authenticated Expedition user’s browser. This typically occurs when the authenticated user inadvertently clicks on a malicious link, potentially facilitating phishing attacks and leading to Expedition browser-session theft.
The CVSS score for this vulnerability is 7, categorizing it as high severity. This means that organizations need to be particularly vigilant as the risk to users' sessions can have widespread implications for data security. Organizations using Expedition should prioritize addressing this vulnerability to minimize risks associated with unauthorized access and data exposure.
Currently, there is no known public exploit for this vulnerability, but the potential for exploitation exists, particularly through social engineering tactics. Organizations must remain aware of this threat and take proactive measures to educate users about safe browsing practices and the dangers of clicking on unknown links.
Given the high severity of this vulnerability, organizations should prioritize patching immediately to protect their systems and users. Regular updates and security assessments, including penetration testing, should be part of a comprehensive security strategy.
Vulnerability Details
The vulnerability allows attackers to execute arbitrary JavaScript code in an authenticated user's browser. The attack vector is network-based, requiring low complexity to exploit, with no privileges required. User interaction is necessary, as the victim must click on a malicious link.
The attack's impact includes a high confidentiality impact, with the potential for unauthorized access to user sessions, while the integrity impact is low. The availability of the service is not affected.
The vulnerability is classified under CWE-79, indicating a reflected cross-site scripting flaw. It was officially published on January 11, 2025, and affects all versions of the Expedition tool prior to 1.2.101.
Technical Analysis
The root cause of this vulnerability lies in the insufficient validation of user input, allowing malicious scripts to be injected into pages viewed by users. The attack vector is primarily network-based, meaning that an attacker can initiate the attack remotely without requiring physical access to the target system.
The attack complexity is low, as it does not require special conditions or extensive knowledge of the system. The attack requires no privileges, making it accessible to any potential attacker who can craft a malicious link. User interaction is necessary, as a victim must click on the link for the attack to succeed.
The confidentiality impact is high due to the possibility of user session theft, while the integrity impact is low since the attacker does not alter the data directly. There is no availability impact associated with this vulnerability.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-0104 is significant. Organizations using Palo Alto Networks Expedition face a potential breach of user sessions, which could lead to unauthorized access to sensitive data and systems. The risk is compounded by the necessity for user interaction, as it relies on the social engineering aspect of phishing attacks.
Given the high CVSS score, this vulnerability requires immediate attention. Organizations should assess their exposure to this vulnerability and implement necessary mitigations swiftly. The blast radius for this vulnerability can be extensive if exploited, as it can affect any authenticated user who interacts with malicious links.
In light of the vulnerability's high severity, organizations should prioritize patching in their immediate security efforts. Regular training and security awareness campaigns can also help mitigate the risks associated with phishing attempts.
