An attacker can make an authenticated HTTP request to trigger these vulnerabilities.A configuration injection vulnerability exists in the `ftp_port` POST parameter.
Security Summary
CVE-2024-39794 involves multiple external configuration control vulnerabilities in the nas.cgi set_nas() proftpd functionality of the Wavlink AC3000 router running firmware version M33A8.V5030.210505. These flaws enable a permission bypass through a specially crafted HTTP request and include a configuration injection vulnerability in the `ftp_port` POST parameter. Published on January 14, 2025, the vulnerability is rated with a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H) and is associated with CWE-15 (External Control of File Name or Path).
Exploitation requires an authenticated attacker with high privileges (PR:H) to send a specially crafted HTTP request over the network (AV:N). The low attack complexity (AC:L) and lack of user interaction (UI:N) allow the attacker to bypass permissions and inject configurations, resulting in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H), compounded by a change in scope (S:C).
