DESCRIPTION:
A security issue has been reported in 2Wire 2700HGV-2 Gateway, which
can be exploited by malicious people to conduct brute force attacks.

The security issue is caused due to session IDs being generated
insecurely, which can be exploited to brute force valid session IDs
and potentially gain access to the web-based management interface.

The security issue is reported in 2700HGV-2 Gateway version
5.29.117.3. Other versions may also be affected.

SOLUTION:
Restrict network access to the web-based management interface.
