It has been reported that FirstClass Desktop Client may be prone to a local buffer overflow vulnerability that could allow attackers to execute arbitrary code on a vulnerable system that may lead to elevated privileges. The issue is reported to exist due to the 'PROXYADDR' variable of the 'LOCAL NETWORK.FCP' configuration file.
This issue is reported to exist in Centrinity FirstClass Desktop Client 7.1.
