CVE-2023-49863Network attack vector

Authenticated file read via URL path traversal

Published Jan 10, 2024 · Updated Nov 4, 2025

Path traversal in WWBN AVideo dev master commit 15fed957fb allows remote authenticated users to read arbitrary server files via a crafted URL. The endpoint passes the attacker-controlled downloadURL_webpimage value through url_get_contents, whose local-path helper discards the URL prefix and reads an unchecked path after /videos/. Upload permission is required; retrieved content is stored as a video image and can expose files such as configuration.php, including its encryption salt.
