Description

Pravus has discovered two vulnerabilities in Diskeeper, which can be exploited by malicious people to cause a DoS (Denial of Service) or disclose certain system information.

The vulnerabilities are caused due to input validation errors within the Diskeeper service (DkService.exe) when handling arguments passed to RPC requests with opcode 0x01. These can be exploited to crash the service or gain knowledge of certain system information (e.g. Windows version, address of loaded modules) via a specially crafted RPC request sent to default port 31038/TCP.

The vulnerabilities are confirmed in Diskeeper 2007 - ProPremier and reportedly affects Diskeeper 9 Professional. Other versions may also be affected.


Solution
Restrict access to the service.
