CVE-2025-8050 is a vulnerability classified under CWE-73 (External Control of File Name or Path) affecting OpenText Flipper version 3.1.2. This vulnerability allows an attacker to perform a path traversal attack by externally controlling the file name or path parameters processed by the application. Specifically, the application fails to properly sanitize or validate user-supplied input that determines file paths, enabling attackers to traverse directories and access files outside the intended directory scope. The vulnerability can be exploited remotely over the network without requiring authentication, although user interaction is necessary to trigger the exploit. The CVSS 4.0 base score is 5.3 (medium severity), reflecting the moderate impact on confidentiality, integrity, and availability, with low complexity and no privileges required. Successful exploitation could lead to unauthorized disclosure of sensitive files hosted on the server, potentially exposing configuration files, credentials, or other critical data. While no known exploits are currently reported in the wild, the vulnerability poses a risk to organizations using this specific version of OpenText Flipper, especially if the server hosts sensitive or regulated data. The vulnerability does not affect the availability of the system directly but can compromise data confidentiality and integrity. The issue was publicly disclosed on October 21, 2025, and no official patches have been linked yet, indicating the need for immediate attention and mitigation by affected users.

For European organizations, this vulnerability could lead to unauthorized access to sensitive files on servers running OpenText Flipper 3.1.2, potentially exposing confidential business information, personal data protected under GDPR, or intellectual property. The exposure of such data could result in regulatory penalties, reputational damage, and operational disruptions. Since the vulnerability requires no authentication and can be triggered remotely, attackers could exploit it to gather information for further attacks or data exfiltration. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are particularly at risk due to the sensitive nature of their data and the regulatory environment in Europe. The medium severity rating suggests that while the vulnerability is not immediately catastrophic, it still represents a significant security risk that must be addressed promptly to prevent escalation or chained attacks. The lack of known exploits in the wild provides a window for proactive defense, but the ease of exploitation and potential impact on confidentiality warrant urgent mitigation efforts.

1. Immediately upgrade OpenText Flipper to a version where this vulnerability is patched once available. Monitor vendor advisories for official patches. 2. Implement strict input validation and sanitization on all file name and path parameters to prevent path traversal sequences such as '../'. 3. Apply the principle of least privilege to the file system permissions of the Flipper application, ensuring it only has access to necessary directories and files. 4. Use web application firewalls (WAFs) with rules designed to detect and block path traversal attempts targeting the application. 5. Monitor server logs for unusual file access patterns or attempts to access sensitive files outside the intended directories. 6. Restrict user interaction vectors that can trigger file access, such as disabling unnecessary file upload or download features if not required. 7. Conduct regular security assessments and penetration testing focused on file path handling to identify and remediate similar issues. 8. Educate system administrators and security teams about this vulnerability and ensure incident response plans include scenarios involving path traversal attacks.
