The manipulation of the `device.auth.localAdminPassword` argument leads to an unverified password change. It is possible to launch the attack remotely. **Recommendations** For Poly Trio 8300, Trio 8500, Trio 8800, Trio C60, CCX 350, CCX 400, CCX 500, CCX 505, CCX 600, CCX 700, EDGE E100, EDGE E220, EDGE E300, EDGE E320, EDGE E350, EDGE E400, EDGE E450, EDGE E500, EDGE E550, VVX 101, VVX 150, VVX 201, VVX 250, VVX 300, VVX 301, VVX 310, VVX 311, VVX 350, VVX 400, VVX 401, VVX 410, VVX 411, VVX 450, VVX 500, VVX 501, VVX 600, and VVX 601: As a temporary workaround, consider disabling the Configuration File Import component until a patch is available. Restrict access to the `device.auth.localAdminPassword` argument to minimize the risk of exploitation. Avoid using the `device.auth.localAdminPassword` argument in the affected configuration file import until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. **Recommendations** To resolve the issue for each affected version, it is recommended to upgrade the affected component. As a temporary workaround, consider disabling the Diagnostic Telnet Mode until a patch is available. Restrict access to the Diagnostic Telnet Mode to minimize the risk of exploitation. Avoid using the Diagnostic Telnet Mode in the affected devices until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Poly Trio 8800 version 7.2.6.0019 **Description** A critical issue was found in the Test Automation Mode component of the Poly Trio 8800, which can be manipulated to create a backdoor. The attack can be launched on the physical device. Additionally, there is a vulnerability related to undocumented configuration commands in the Poly Lens Management Cloud Registration component of Poly Trio phones and acoustic systems for conference calls, which can allow an attacker to elevate their privileges. **Recommendations** For Poly Trio 8800 version 7.2.6.0019, consider disabling the Test Automation Mode until a patch is available to prevent potential backdoor exploitation. Restrict access to the Poly Lens Management Cloud Registration component to minimize the risk of privilege elevation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Poly Trio 8500 version unknown Poly Trio 8800 version unknown Poly Trio C60 version unknown **Description** A vulnerability was found in the Poly Lens Management Cloud Registration component, affecting an unknown part of it. The manipulation leads to missing authorization, and it is possible to launch the attack on the physical device. The exploit has been disclosed to the public and may be used. This issue is related to deficiencies in the authorization procedure of the Poly Lens application interface for Poly Trio phones and acoustic systems for conference calls. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
