Sterling Trader Data Processing Buffer Overflow

Sterling Trader Data Processing Buffer Overflow
Posted Dec 13, 2011
Authored by Dmitriy Pletnev | Site secunia.com

Secunia Research has discovered a vulnerability in Sterling Trader, which can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to a boundary error in Base.exe when processing network requests (code 176). This can be exploited to cause a stack-based buffer overflow via a specially crafted packet sent to a certain TCP port. Successful exploitation allows execution of arbitrary code, but requires guessing the TCP port, which is dynamically assigned. Version 7.0.2 is affected.
