TITLE

DATAC RealFlex RealWin of HMI Application integer overflow vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2011-001670

DESCRIPTION

Multiple integer overflows in the HMI application in DATAC RealFlex RealWin 2.1 (Build 6.1.10.10) and earlier allow remote attackers to execute arbitrary code via crafted (1) On_FC_MISC_FCS_MSGBROADCAST and (2) On_FC_MISC_FCS_MSGSEND packets, which trigger a heap-based buffer overflow. DATAC RealWin is a SCADA server product that operates a single PC or multiple PCs over a TCP/IP network. DATAC RealWin SCADA Server can exploit vulnerabilities for buffer overflow attacks due to incorrect validation of user-supplied input. Successful exploitation of a vulnerability can execute arbitrary code in an application security context. DATAC RealWin is prone to multiple remote buffer-overflow vulnerabilities because of a failure to properly bounds check user-supplied input. Failed exploit attempts will cause a denial-of-service condition. DATAC RealWin versions 2.1 and prior are vulnerable; other versions may also be affected. ---------------------------------------------------------------------- Meet Secunia @ Microsoft Management Summit (MMS) in Las Vegas, USA (21-25 March). http://secunia.com/company/events/mms_2011/ ---------------------------------------------------------------------- TITLE: RealWin FlexWin Connection Packet Processing Buffer Overflow Vulnerabilities SECUNIA ADVISORY ID: SA43848 VERIFY ADVISORY: Secunia.com http://secunia.com/advisories/43848/ Customer Area (Credentials Required) https://ca.secunia.com/?page=viewadvisory&vuln_id=43848 RELEASE DATE: 2011-03-22 DISCUSS ADVISORY: http://secunia.com/advisories/43848/#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/43848/ 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=43848 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 multiple vulnerabilities in RealWin, which can be exploited by malicious people to compromise a vulnerable system.
