VAR-200803-0288

Vulnerability from variot - Updated: 2023-12-18 12:32

Vocera Communications wireless handsets, when using Protected Extensible Authentication Protocol (PEAP), do not validate server certificates, which allows remote wireless access points to steal hashed passwords and conduct man-in-the-middle (MITM) attacks. Multiple VoIP products are prone to a security-bypass vulnerability in their PEAP implementation because their software fails to properly validate server certificates. Successfully exploiting this issue allows attackers to perform man-in-the-middle attacks by impersonating trusted authentication servers. This will aid in further attacks. The following products are prone to this issue: - Vocera Communications System badges - Cisco Wireless IP Phone 7921 Other devices and packages may also be affected
