TITLE

DATAC RealWin Multiple Stack Buffer Overflow Vulnerabilities

DESCRIPTION

Multiple stack-based buffer overflows in DATAC RealWin 2.0 Build 6.1.8.10 and earlier allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long (1) SCPC_INITIALIZE, (2) SCPC_INITIALIZE_RF, or (3) SCPC_TXTEVENT packet. NOTE: it was later reported that 1.06 is also affected by one of these requests. RealFlex RealWin HMI service (912/tcp) Contains multiple stack buffer overflow vulnerabilities. RealFlex RealWin HMI service (912/tcp) Contains two stack buffer overflow vulnerabilities. The first one is, SCPC_INITIALIZE() and SCPC_INITIALIZE_RF() In the function sprintf() Use, the second is SCPC_TXTEVENT() In the function strcpy() Due to the use of each.RealFlex RealWin HMI Service disruption by a third party with access to the service (DoS) An attacker may be attacked or execute arbitrary code. RealWin is a data acquisition and monitoring control system (SCADA) server product running on the Windows platform. - A boundary error occurred while processing the \"SCPC_INITIALIZE\" and \"SCPC_INITIALIZE_RF\" messages. Sending a specially constructed message to the TCP 912 port triggered a stack-based buffer overflow. - Handling \"SCPC_TXTEVENT\" messages with boundary errors, sending specially constructed messages to the TCP 912 port can trigger a stack-based buffer overflow. Failed exploit attempts will cause a denial-of-service condition. DATAC RealWin versions 2.0 and prior are vulnerable; other versions may also be affected. ---------------------------------------------------------------------- Windows Applications Insecure Library Loading The Official, Verified Secunia List: http://secunia.com/advisories/windows_insecure_library_loading/ The list is continuously updated as we confirm the vulnerability reports so check back regularly too see if any of your apps are affected. ---------------------------------------------------------------------- TITLE: RealWin Packet Processing Buffer Overflow Vulnerabilities SECUNIA ADVISORY ID: SA41849 VERIFY ADVISORY: Secunia.com http://secunia.com/advisories/41849/ Customer Area (Credentials Required) https://ca.secunia.com/?page=viewadvisory&vuln_id=41849 RELEASE DATE: 2010-10-18 DISCUSS ADVISORY: http://secunia.com/advisories/41849/#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/41849/ 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=41849 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 RealWin, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.
