{"vuid":"VU#496040","idnumber":"496040","name":"Sielco Sistemi Winlog server stack overflow","keywords":["Sielco","Sistemi","Winlog","scada"],"overview":"Sielco Sistemi Winlog TCP/IP server contains a stack overflow vulnerability","clean_desc":"According to Sielco Sistemi's website: \"Winlog is a software package for SCADA/HMI applications with web support, OPC client and a wide library of communication drivers and protocols for most PLCs (Siemens, Omron, Allen Bradley, Modbus, etc.)\" Sielco Sistemi Winlog has the capability to accept remote connections by enabling the \"Run TCP/IP server\" option. The server listens on port 46823/tcp. A specially crafted packet from a remote attacker can cause a stack overflow possibly allowing an attacker to execute arbitrary code. For additional information see ICS-CERT Advisory ICSA-11-017-02. Public exploit code is available for this vulnerability.","impact":"A remote attacker can cause the device to crash and may be able to execute arbitrary code.","resolution":"Upgrade Sielco Sistemi recommends that users update their Winlog Lite and Winlog Pro to version 2.07.01.","workarounds":"Restrict Access Enable firewall rules to restrict access for port 46823/tcp to only trusted sources.","sysaffected":"","thanks":"Thanks to Luigi Auriemma for reporting this vulnerability.","author":"This document was written by Michael Orlando.","public":["http://www.us-cert.gov/control_systems/pdf/ICSA-11-017-02.pdf","http://www.exploit-db.com/exploits/15992/","http://www.sielcosistemi.com/download/WinlogLite_Setup.exe","http://www.sielcosistemi.com/download/Winlog_Setup_SF.exe"],"cveids":["CVE-2011-0517"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2011-01-18T15:09:40Z","publicdate":"2011-01-17T00:00:00Z","datefirstpublished":"2011-02-03T15:12:20Z","dateupdated":"2011-02-03T15:12:21Z","revision":13,"vrda_d1_directreport":"0","vrda_d1_population":"2","vrda_d1_impact":"2","cam_widelyknown":"20","cam_exploitation":"0","cam_internetinfrastructure":"2","cam_population":"2","cam_impact":"19","cam_easeofexploitation":"10","cam_attackeraccessrequired":"7","cam_scorecurrent":"1.09725","cam_scorecurrentwidelyknown":"1.09725","cam_scorecurrentwidelyknownexploited":"2.09475","ipprotocol":"tcp","cvss_accessvector":"","cvss_accesscomplexity":"","cvss_authentication":null,"cvss_confidentialityimpact":"","cvss_integrityimpact":"","cvss_availabilityimpact":"","cvss_exploitablity":null,"cvss_remediationlevel":"","cvss_reportconfidence":"","cvss_collateraldamagepotential":"","cvss_targetdistribution":"","cvss_securityrequirementscr":"","cvss_securityrequirementsir":"","cvss_securityrequirementsar":"","cvss_basescore":"","cvss_basevector":"","cvss_temporalscore":"","cvss_environmentalscore":"","cvss_environmentalvector":"","metric":1.09725,"vulnote":null}
