Joey Mengele has discovered a vulnerability in Windows RSH daemon, which can be exploited by malicious users to compromise a vulnerable system.
The vulnerability is caused due to a boundary error within the Windows RSH daemon (rshd.exe) process and can be exploited to cause a stack-based buffer overflow via an overly long, specially crafted packet sent to default port 514/TCP.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in version 1.7 and 1.8. Other versions may also be affected.
Solution: Grant only trusted users access to the application.
