CitectSCADA ODBC Server Remote Buffer Overflow
Critical Nessus Plugin ID 33201
SynopsisThe remote Windows host contains an application that is affected by a buffer overflow vulnerability.
DescriptionThe 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.
SolutionEither disable the ODBC server service or contact the vendor to obtain Hotfix HF700R138255 (containing 'Client.dll' version 18.104.22.16825) and apply that.
