CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2022-30547 is a critical-severity Path Traversal (CWE-22) vulnerability in Wwbn Avideo. Its CVSS base score is 9.9 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 0.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
A directory traversal vulnerability exists in the unzipDirectory functionality of WWBN AVideo version 11.6 and the development master commit 3f7c0364. Tracked as CVE-2022-30547 and assigned CWE-22, the flaw allows a specially crafted HTTP request to trigger arbitrary command execution. The issue carries a CVSS 3.1 score of 9.9, reflecting network attack vector, low attack complexity, low privileges required, and impacts across confidentiality, integrity, and availability with a scope change.
An authenticated attacker can send a crafted HTTP request to the affected unzipDirectory component and achieve arbitrary command execution on the server. The attack requires no user interaction and can be performed remotely over the network.
Public references include a Talos Intelligence vulnerability report (TALOS-2022-1547) and database update scripts hosted in the AVideo GitHub repository that address version 12.0.
EPSS for the CVE rose from low values after disclosure to a peak of 0.3369 on 2025-12-11 before receding to the current 0.2074, indicating that exploitation interest emerged well after the initial publication.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Validates pathnames and filenames to prevent traversal outside intended directories.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.
PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing in development catches path traversal via static/dynamic analysis.
Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.
Application security requirements include rules for safe file handling and canonicalization.
Secure architecture principles require least-privilege file access and directory isolation.
Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.
Information access restriction limits which files an application may read or write.
