CVE-2025-12250 is a path traversal vulnerability identified in OpenWGA version 7.11.12 Build 737, specifically within the TMLScript API's WGA.File component. Path traversal vulnerabilities allow attackers to manipulate file path inputs to access files and directories outside the intended scope, potentially exposing sensitive data or configuration files. This vulnerability can be exploited remotely without user interaction, but requires the attacker to have high privileges on the system, which limits the ease of exploitation to some extent. The vulnerability impacts confidentiality by allowing unauthorized file access and integrity by potentially enabling attackers to read or modify critical files. The vendor has not responded to early disclosure attempts, and no official patches have been released, although a public exploit is available, increasing the risk of exploitation. The CVSS 4.0 score is 5.1 (medium), reflecting network attack vector, low complexity, no user interaction, but requiring high privileges and causing low impact on confidentiality, integrity, and availability. The lack of vendor response and patch availability means organizations must rely on mitigations such as access restrictions and input validation. OpenWGA is a web content management system used in various enterprise environments, making this vulnerability relevant to organizations relying on it for internal or external web services.

For European organizations, this vulnerability poses a risk of unauthorized access to sensitive files hosted on OpenWGA servers, potentially exposing confidential business information, user data, or internal configurations. The ability to remotely exploit the flaw without user interaction increases the threat surface, especially in environments where OpenWGA is exposed to the internet or accessible by multiple users. Although exploitation requires high privileges, attackers who have already gained elevated access (e.g., through other vulnerabilities or insider threats) can leverage this flaw to escalate their impact. This could lead to data breaches, disruption of web services, or further lateral movement within networks. The absence of vendor patches and the presence of public exploits heighten the urgency for European organizations to implement compensating controls. The impact is particularly significant for sectors with stringent data protection requirements, such as finance, healthcare, and government institutions within Europe.

1. Immediately restrict network access to OpenWGA instances running version 7.11.12 Build 737, especially from untrusted networks or the internet. 2. Implement strict input validation and sanitization on all file path parameters processed by the TMLScript API to prevent path traversal attempts. 3. Employ application-layer firewalls or web application firewalls (WAFs) with custom rules to detect and block path traversal payloads targeting OpenWGA. 4. Isolate OpenWGA servers in segmented network zones with limited access to sensitive backend systems and files. 5. Monitor logs for suspicious file access patterns indicative of path traversal exploitation attempts. 6. Engage with the vendor or community to obtain updates or patches as soon as they become available. 7. Consider upgrading to a newer, unaffected version of OpenWGA once a patch is released. 8. Conduct regular security assessments and penetration tests focusing on file handling components of OpenWGA. 9. Educate system administrators about the vulnerability and the importance of applying mitigations promptly.
