Some VX800v v1.0 web interface endpoints transmit sensitive information over unencrypted HTTP due to missing application layer encryption, allowing a network adjacent attacker to intercept this traffic and compromise its confidentiality.

Improper link resolution in USB HTTP access path in VX800v v1.0 allows a crafted USB device to expose root filesystem contents, giving an attacker with physical access read‑only access to system files.

Improper handling of exceptional conditions in VX800v v1.0 in SIP processing allows an attacker to flood the device with crafted INVITE messages, blocking all voice lines and causing a denial of service on incoming calls.

Improper link resolution in the VX800v v1.0 SFTP service allows authenticated adjacent attackers to use crafted symbolic links to access system files, resulting in high confidentiality impact and limited integrity risk.

A weakness in the web interface’s application layer encryption in VX800v v1.0 allows an adjacent attacker to brute force the weak AES key and decrypt intercepted traffic. Successful exploitation requires network proximity but no authentication, and may result in high impact to confidentiality, integrity, and availability of transmitted data.
