EUVDB-ID: #VU68494

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-41741

CWE-ID: CWE-125 - Out-of-bounds read

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service attack.

The vulnerability exists due to a boundary condition within the ngx_http_mp4_module module when handling MP4 files. A remote attacker can pass a specially crafted file to the server, trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service attack.
