TITLE

Optima PLC APIFTP Server Denial of Service Vulnerability (CNVD-2011-4863)

DESCRIPTION

Optima is software that controls the PLC via the SCADA/HMI interface. The APIFTP server is a file server. The Optima PLC APIFTP server (APIFTPServer.exe) handles some packets with errors. Sending a specially crafted message to the TCP 10260 port triggers a null pointer application and causes a stack-based overflow. ---------------------------------------------------------------------- SC World Congress, New York, USA, 16 November 2011 Visit the Secunia booth (#203) and discover how you can improve your handling of third party programs: http://secunia.com/resources/events/sc_2011/ ---------------------------------------------------------------------- TITLE: Optima PLC APIFTP Server Two Denial of Service Vulnerabilities SECUNIA ADVISORY ID: SA46830 VERIFY ADVISORY: Secunia.com http://secunia.com/advisories/46830/ Customer Area (Credentials Required) https://ca.secunia.com/?page=viewadvisory&vuln_id=46830 RELEASE DATE: 2011-11-14 DISCUSS ADVISORY: http://secunia.com/advisories/46830/#comments AVAILABLE ON SITE AND IN CUSTOMER AREA: * Last Update * Popularity * Comments * Criticality Level * Impact * Where * Solution Status * Operating System / Software * CVE Reference(s) http://secunia.com/advisories/46830/ ONLY AVAILABLE IN CUSTOMER AREA: * Authentication Level * Report Reliability * Secunia PoC * Secunia Analysis * Systems Affected * Approve Distribution * Remediation Status * Secunia CVSS Score * CVSS https://ca.secunia.com/?page=viewadvisory&vuln_id=46830 ONLY AVAILABLE WITH SECUNIA CSI AND SECUNIA PSI: * AUTOMATED SCANNING http://secunia.com/vulnerability_scanning/personal/ http://secunia.com/vulnerability_scanning/corporate/wsus_sccm_3rd_third_party_patching/ DESCRIPTION: Luigi Auriemma has discovered two vulnerabilities in Optima PLC, which can be exploited by malicious people to cause a DoS (Denial of Service).
