Summary

CVE-2025-34442 is a medium-severity Exposure of Sensitive System Information to an Unauthorized Control Sphere (CWE-497) vulnerability in Wwbn Avideo. Its CVSS base score is 6.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique System Information Discovery (T1082); ranked in the top 45% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

AVideo versions prior to 20.1 contain an information disclosure vulnerability tracked as CVE-2025-34442. Multiple public API endpoints return metadata containing absolute filesystem paths to media files, exposing the underlying server directory structure. The issue is classified under CWE-497 and carries a CVSS 4.0 score of 6.9 reflecting network attack vector, low complexity, and no required authentication or user interaction.

Unauthenticated remote attackers can query the affected endpoints to obtain full server paths. This information can be used to map the filesystem layout and support more targeted follow-on attacks against the AVideo installation or the host system.

Public references, including GitHub commits 4a53ab2056 and dbe3e91c54 along with the VulnCheck advisory, indicate that the path disclosure has been addressed in version 20.1. Security practitioners should apply the available updates to eliminate the exposed endpoints.

The EPSS score for this CVE rose from a low baseline to a peak of 0.4749 before settling at the current value of 0.4080, indicating emerging exploitation interest after disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Enforces approved authorizations for logical access, directly stopping unauthorized actors from reaching sensitive system information.

Enforces information flow policies that block sensitive system data from crossing into unauthorized control spheres.

Limits privileges so that only the minimum necessary access is granted, reducing the chance of exposing system-level details.

Controls communications at external and key internal boundaries to keep sensitive system information inside authorized spheres.
