Vulnerability Information

Severity: High
Vulnerability Published: 2008-06-11
Patch Published: 2008-06-10
CVE [?]: CVE-2008-2639
CPE [?]: N/A

Synopsis

The remote Windows host contains an application that is affected by a buffer overflow vulnerability.

Description

The version of CitectSCADA installed on the remote host includes an ODBC server that listens by default on TCP port 20222 and reportedly is affected by a stack-buffer overflow vulnerability.

Using a specially-crafted sequence of packets, an unauthenticated remote attacker who can connect to the server can leverage this issue to crash the affected service or to execute code on the affected host with SYSTEM-level privileges.

Solution

Either disable the ODBC server service or contact the vendor to obtain Hotfix HF700R138255 (containing 'Client.dll' version 7.0.0.10025) and apply that.
