A vulnerability has been discovered in the TR069 protocol that can potentially affect all Automatic Configuration Servers (ACS). The issue has been fixed in the Home Device Manager (HDM) product from Alcatel-Lucent with an anti-spoofing filter. HDM allows service providers to remotely manage CPEs, such as residential gateways, IP set-top boxes, and VoIP terminal adapters that comprise a home networking environment. The vulnerability allows an attacker to perform impersonation attacks by spoofing CPE using tr-069 (cwmp) Protocol. An attacker could gain unauthorized access to third-party SIP Credentials for the spoofed device and perform illegal activities (phone fraud). The vulnerability has been tested and confirmed. Versions prior to 4.1.10 may be affected.
