Summary
In Yealink MeetingBoard Pro before 331.320.0.64, the Web management module has a front-end validation bypass vulnerability. An attacker with administrator privileges can modify the page DOM to bypass front-end UI control logic and invoke screenshot-related interfaces, triggering the screenshot function by circumventing front-end interface restrictions. Exploitation can occur only when the attacker has a valid administrator account within the local network.

Summary
Certain Yealink terminal devices before 2026-04-21 contain an improper access control vulnerability in the Wi-Fi 802.1X PEAP network configuration function. This flaw exposes deployed 802.1X network access authentication credentials to unauthorized users. The latest Yealink firmware has addressed this vulnerability by restricting 802.1X configuration modification privileges to administrator accounts only by default.

Title
Yealink SIP-T33G < 124.87.0.0 Race Condition via Diagnostic File Deletion
Summary
Yealink SIP-T33G firmware versions 124.86.x.x prior to 124.87.0.0 contain a race condition vulnerability that allows authenticated attackers to interrupt active diagnostic processes by concurrently deleting output files written to predictable paths under the diagnostic directory. Attackers can trigger a diagnostic operation such as traceroute or ping and simultaneously invoke the file deletion endpoint to terminate the running process, leaving the system in an inconsistent state.

Title
Yealink SIP-T46U Web FastCGI Service tftpuploadiperf mod_webd.TFTPUploadIperf command injection
Summary
A vulnerability was identified in Yealink SIP-T46U 108.86.0.118. Affected by this vulnerability is the function mod_webd.TFTPUploadIperf of the file /api/inner/tftpuploadiperf of the component Web FastCGI Service. The manipulation of the argument ip/port leads to command injection. The attack needs to be initiated within the local network. The exploit is publicly available and might be used. Upgrading to version 108.87.0.23 addresses this issue. Upgrading the affected component is recommended. The vendor explains: "It has been fixed (...) for our technical support branch. However, please note that this specific support branch firmware is not publicly released yet."
