Description:
securfrog has discovered a vulnerability in IpSwitch WS_FTP Server with SSH, which can be exploited by malicious users to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the SSH Server Service (SSHServer.exe) when handling arguments to the "opendir" command. This can be exploited to cause a stack-based buffer overflow by passing an overly long argument to the affected command.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is confirmed in IpSwitch WS_FTP Server with SSH version 6.1. Other versions may also be affected.
Solution:
Grant only trusted users access to the SSH Server Service.
