Vulnerability Details
The vulnerability described in CVE-2025-21528 is found in the Primavera P6 Enterprise Project Portfolio Management application, specifically in the Web Access component. The affected versions include 20.12.1.0 to 20.12.21.5, 21.12.1.0 to 21.12.20.0, 22.12.1.0 to 22.12.16.0, and 23.12.1.0 to 23.12.10.0.
The CVSS score of 4.3 indicates a medium severity level, suggesting that the integrity impact is low, while confidentiality and availability impacts are marked as none. This score highlights the need for organizations to take appropriate action.
The vulnerability falls under CWE-352, indicating issues related to cross-site request forgery.
Technical Analysis
The root cause of CVE-2025-21528 lies in the application's handling of user requests. An unauthenticated attacker can exploit this vulnerability due to the requirement for user interaction, which means that some form of user action is necessary to trigger the vulnerability. The attack vector is network-based with low complexity, meaning that an attacker can leverage this vulnerability without needing high-level skills.
Furthermore, the attack requires no privileges and demands user interaction, which poses a risk primarily when users are tricked into performing actions that facilitate the attack. The integrity impact is low, signifying that while the attacker may alter data, the overall system remains available and confidential.
Risk & Impact Analysis
The real-world deployment of this vulnerability poses significant risks to organizations utilizing Oracle's Primavera P6. Attackers may leverage this vulnerability to gain unauthorized access to sensitive project data, which can lead to unauthorized modifications or deletions. The potential blast radius is considerable due to the broad user base and the interconnected nature of project management data.
Given the CVSS score of 4.3, organizations should assess this vulnerability within their risk management frameworks. The urgency for addressing this vulnerability is medium, which indicates it should be prioritized within the next patch cycle.
