A SQL injection was found in Linknat VOS3000/VOS2009, a popular VoIP
softswitch, that could allow remote attackers to gain access to the
credentials stored in plain-text.

Application: Linknat VOS3000/VOS2009
Versions Affected: 2.1.1.5, 2.1.1.8, 2.1.2.0

The SQLi reported is time-based blind. Since it is not an in-band SQLi, the
results can be gathered from the output of welcome.jsp during the same
session.

(1st request)

POST    http://target/eng/login.jsp
PARAM   loginType=1
        name=' union select 1,2,@@version,'hello',5,6#
