Ruben Santamarta has discovered a vulnerability in RealWin, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the processing of TCP packets received on port 910 by default. This can be exploited to cause a stack-based buffer overflow via an overly large INFOTAG/SET_CONTROL packet.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in RealWin demo version 2.0 (build 6.0.10.37). Other versions may also be affected.

Solution
Restrict network access to trusted users only.
