TITLE

DATAC RealFlex RealWin of HMI Application stack-based buffer overflow vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2011-001669

DESCRIPTION

Multiple stack-based buffer 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 (1) a long username in an On_FC_CONNECT_FCS_LOGIN packet, and crafted (2) On_FC_CTAGLIST_FCS_CADDTAG, (3) On_FC_CTAGLIST_FCS_CDELTAG, (4) On_FC_CTAGLIST_FCS_ADDTAGMS, (5) On_FC_RFUSER_FCS_LOGIN, (6) unspecified "On_FC_BINFILE_FCS_*FILE", (7) On_FC_CGETTAG_FCS_GETTELEMETRY, (8) On_FC_CGETTAG_FCS_GETCHANNELTELEMETRY, (9) On_FC_CGETTAG_FCS_SETTELEMETRY, (10) On_FC_CGETTAG_FCS_SETCHANNELTELEMETRY, and (11) On_FC_SCRIPT_FCS_STARTPROG packets to port 910. (2)On_FC_CTAGLIST_FCS_CADDTAG (3)On_FC_CTAGLIST_FCS_CDELTAG (4)On_FC_CTAGLIST_FCS_ADDTAGMS (5)On_FC_RFUSER_FCS_LOGIN (6)unspecified "On_FC_BINFILE_FCS_*FILE (7)On_FC_CGETTAG_FCS_GETTELEMETRY (8)On_FC_CGETTAG_FCS_GETCHANNELTELEMETRY (9)On_FC_CGETTAG_FCS_SETTELEMETRY (10)On_FC_CGETTAG_FCS_SETCHANNELTELEMETRY (11)On_FC_SCRIPT_FCS_STARTPROG packets to port 910. 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. 6) An input validation error when processing "On_FC_MISC_FCS_MSGBROADCAST" packets can be exploited to cause a heap-based buffer overflow via a specially crafted packet sent to TCP port 910. 7) An input validation error when processing "On_FC_MISC_FCS_MSGSEND" packets can be exploited to cause a heap-based buffer overflow via a specially crafted packet sent to TCP port 910. The vulnerabilities are confirmed in version 2.1 Build 6.1.10.10. SOLUTION: Restrict access to trusted hosts only (e.g. via network access control lists).
