CVE-2025-34442 is a vulnerability classified under CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere) affecting the AVideo platform developed by World Wide Broadcast Network. Versions prior to 20.1 of AVideo expose absolute filesystem paths through multiple public API endpoints. These API responses include metadata that reveals the full server paths to media files stored on the backend. Such disclosure of internal directory structures can provide attackers with valuable reconnaissance data, enabling them to better understand the server environment and potentially identify other vulnerabilities or misconfigurations. The vulnerability is remotely exploitable without authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The CVSS score of 6.9 reflects a medium severity, primarily due to the confidentiality impact (VC:L), with limited impacts on integrity and availability (VI:L, VA:L). Although no exploits have been reported in the wild, the information leakage can facilitate more targeted and effective attack chains, such as path traversal, privilege escalation, or unauthorized file access. The vulnerability does not require special privileges or user interaction, increasing its risk profile. The absence of patch links suggests that remediation involves upgrading to version 20.1 or later, where this issue is presumably fixed. Organizations relying on AVideo for media streaming or content delivery should audit their API responses to ensure no sensitive path information is leaked and apply updates promptly to mitigate exposure.

For European organizations, the exposure of absolute filesystem paths can significantly aid attackers in reconnaissance activities, increasing the likelihood of successful exploitation of other vulnerabilities or misconfigurations. Media companies, broadcasters, and content delivery networks using AVideo are particularly at risk, as attackers could leverage this information to map server structures and target critical assets. This could lead to unauthorized access to sensitive media files, potential data breaches, or service disruptions if chained with other exploits. The confidentiality impact is the most direct, but integrity and availability could be indirectly affected if attackers use the disclosed information to escalate privileges or execute arbitrary code. Given the medium severity and ease of exploitation without authentication, organizations face a tangible risk that necessitates timely mitigation. The lack of known exploits in the wild reduces immediate urgency but does not eliminate the threat, especially as attackers often develop exploits after vulnerability disclosure.

1. Upgrade AVideo to version 20.1 or later, where the vulnerability is addressed and absolute filesystem paths are no longer exposed via public APIs. 2. Conduct a thorough audit of all API endpoints to verify that no sensitive system information, including absolute paths, is leaked in metadata or responses. 3. Implement strict input validation and output encoding on API responses to prevent accidental disclosure of internal server details. 4. Employ network-level controls such as web application firewalls (WAFs) to monitor and block suspicious requests targeting API endpoints. 5. Restrict API access where possible, using authentication and authorization mechanisms to limit exposure to trusted users or systems. 6. Monitor logs for unusual access patterns or reconnaissance attempts targeting AVideo APIs. 7. Educate development and operations teams about secure coding practices to avoid similar information disclosure issues in future releases. 8. If immediate upgrade is not feasible, consider temporary mitigations such as disabling vulnerable API endpoints or filtering sensitive data in API responses at the proxy or application layer.
