CVE-2025-58957 is a security vulnerability classified under CWE-862, which pertains to Missing Authorization. This vulnerability affects the VPSUForm product developed by Vikas Ratudi, specifically versions up to 3.2.20. The core issue is an incorrectly configured access control mechanism that fails to properly enforce authorization checks. As a result, users with limited privileges (requiring at least some level of authentication) can perform actions or access resources beyond their intended permissions. The CVSS v3.1 base score is 4.3, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) reveals that the vulnerability is exploitable remotely over the network with low attack complexity, requires privileges (PR:L) but no user interaction, and impacts integrity by allowing unauthorized modification or manipulation of data without affecting confidentiality or availability. No known exploits are currently in the wild, and no patches have been linked or published yet. The vulnerability arises from missing or insufficient authorization checks within the VPSUForm application, which could allow an authenticated but low-privileged user to escalate their privileges or perform unauthorized actions that compromise data integrity. This type of vulnerability is critical to address because it undermines the fundamental security principle of least privilege and can lead to unauthorized data manipulation or unauthorized operations within the affected system.

For European organizations using VPSUForm, this vulnerability could lead to unauthorized modification of data or unauthorized actions within the application by users who should not have such privileges. This can result in data integrity issues, potential disruption of business processes, and compliance risks, especially under regulations like GDPR where data protection and integrity are paramount. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that rely on VPSUForm for form processing or data collection could face operational risks and reputational damage if this vulnerability is exploited. Although the vulnerability does not directly affect confidentiality or availability, the integrity impact can still have significant downstream effects, such as incorrect data processing, fraud, or erroneous decision-making. The requirement for some level of privileges to exploit the vulnerability means that insider threats or compromised accounts pose a particular risk. European organizations must be vigilant in monitoring access controls and user privileges within VPSUForm deployments to mitigate potential exploitation.

1. Implement strict access control policies within VPSUForm by reviewing and correcting authorization checks to ensure that users can only perform actions permitted by their roles. 2. Conduct a thorough code audit focusing on authorization logic to identify and remediate missing or incorrect access control enforcement. 3. Employ role-based access control (RBAC) or attribute-based access control (ABAC) mechanisms to granularly define and enforce permissions. 4. Monitor and log user activities within VPSUForm to detect anomalous behavior indicative of privilege abuse or unauthorized actions. 5. Restrict administrative or elevated privileges to the minimum number of users and enforce strong authentication mechanisms for these accounts. 6. Until an official patch is released, consider implementing compensating controls such as network segmentation, limiting access to VPSUForm to trusted users, and applying web application firewalls (WAF) with custom rules to detect and block unauthorized requests. 7. Educate users and administrators about the risks of privilege escalation and the importance of safeguarding credentials. 8. Stay updated with vendor advisories and apply patches promptly once available.
