VAR-201204-0134
Vulnerability from variot - Updated: 2025-04-11 22:53The web server in the ECOM Ethernet module in Koyo H0-ECOM, H0-ECOM100, H2-ECOM, H2-ECOM-F, H2-ECOM100, H4-ECOM, H4-ECOM-F, and H4-ECOM100 allows remote attackers to cause a denial of service (resource consumption) via unspecified vectors. Koyo ECOM100 Ethernet is an Ethernet module. This module is used for communication between the PLC and the control system. There are several security vulnerabilities in Koyo ECOM100 Ethernet, including: (1) Using an 8-byte password weak authentication mechanism. (2) There is a replay attack. (3) The WEB server does not have any verification mechanism. (4) There is a buffer overflow in the WEB server. (5) There is a cross-site scripting attack on the WEB server. A buffer-overflow vulnerability. 2. A denial-of-service vulnerability. 3. Multiple security-bypass vulnerabilities. 4. A cross site-scripting vulnerability. Attackers can exploit these issues to execute arbitrary code in the context of the affected application, cause denial-of-service conditions, bypass some security restrictions, allow an attacker to steal cookie-based information, or execute script code in the context of the browser of an unsuspecting user; other attacks may also be possible. ----------------------------------------------------------------------

"data": "The web server in the ECOM Ethernet module in Koyo H0-ECOM, H0-ECOM100, H2-ECOM, H2-ECOM-F, H2-ECOM100, H4-ECOM, H4-ECOM-F, and H4-ECOM100 allows remote attackers to cause a denial of service (resource consumption) via unspecified vectors. Koyo ECOM100 Ethernet is an Ethernet module. This module is used for communication between the PLC and the control system. There are several security vulnerabilities in Koyo ECOM100 Ethernet, including: (1) Using an 8-byte password weak authentication mechanism. (2) There is a replay attack. (3) The WEB server does not have any verification mechanism. (4) There is a buffer overflow in the WEB server. (5) There is a cross-site scripting attack on the WEB server. A buffer-overflow vulnerability. \n2. A denial-of-service vulnerability. \n3. Multiple security-bypass vulnerabilities. \n4. A cross site-scripting vulnerability. \nAttackers can exploit these issues to execute arbitrary code in the context of the affected application, cause denial-of-service conditions, bypass some security restrictions, allow an attacker to steal cookie-based information, or execute script code in the context of the browser of an unsuspecting user; other attacks may also be possible. ----------------------------------------------------------------------\n\nSecunia is hiring!\n\nFind your next job here:\n\nhttp://secunia.com/company/jobs/\n\n----------------------------------------------------------------------\n\nTITLE:\nKoyo ECOM100 Ethernet Module Cross-Site Scripting and Denial of\nService Vulnerabilities\n\nSECUNIA ADVISORY ID:\nSA47735\n\nVERIFY ADVISORY:\nSecunia.com\nhttp://secunia.com/advisories/47735/\nCustomer Area (Credentials Required)\nhttps://ca.secunia.com/?page=viewadvisory\u0026vuln_id=47735\n\nRELEASE DATE:\n2012-01-23\n\nDISCUSS ADVISORY:\nhttp://secunia.com/advisories/47735/#comments\n\nAVAILABLE ON SITE AND IN CUSTOMER AREA:\n * Last Update\n * Popularity\n * Comments\n * Criticality Level\n * Impact\n * Where\n * Solution Status\n * Operating System / Software\n * CVE Reference(s)\n\nhttp://secunia.com/advisories/47735/\n\nONLY AVAILABLE IN CUSTOMER AREA:\n * Authentication Level\n * Report Reliability\n * Secunia PoC\n * Secunia Analysis\n * Systems Affected\n * Approve Distribution\n * Remediation Status\n * Secunia CVSS Score\n * CVSS\n\nhttps://ca.secunia.com/?page=viewadvisory\u0026vuln_id=47735\n\nONLY AVAILABLE WITH SECUNIA CSI AND SECUNIA PSI:\n * AUTOMATED SCANNING\n\nhttp://secunia.com/vulnerability_scanning/personal/\nhttp://secunia.com/vulnerability_scanning/corporate/wsus_sccm_3rd_third_party_patching/\n\nDESCRIPTION:\nMultiple vulnerabilities have been reported in Koyo ECOM100 Ethernet\nModule, which can be exploited by malicious people to conduct\ncross-site scripting attacks and cause a DoS (Denial of Service). \n\n1) Certain unspecified input is not properly sanitised before being\nreturned to the user. \n\nSOLUTION:\nFilter malicious characters and character sequences in a proxy. \nRestrict access to trusted hosts only. \n\nPROVIDED AND/OR DISCOVERED BY:\nICS-CERT credits Reid Wightman via Digital Bond\\x92s SCADA Security\nScientific Symposium (S4). \n\nORIGINAL ADVISORY:\nICS-CERT:\nhttp://www.us-cert.gov/control_systems/pdf/ICS-ALERT-12-020-05.pdf\n\nOTHER REFERENCES:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\nDEEP LINKS:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\nEXTENDED DESCRIPTION:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\nEXTENDED SOLUTION:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\nEXPLOIT:\nFurther details available in Customer Area:\nhttp://secunia.com/vulnerability_intelligence/\n\n----------------------------------------------------------------------\n\nAbout:\nThis Advisory was delivered by Secunia as a free service to help\nprivate users keeping their systems up to date against the latest\nvulnerabilities. \n\nSubscribe:\nhttp://secunia.com/advisories/secunia_security_advisories/\n\nDefinitions: (Criticality, Where etc.)\nhttp://secunia.com/advisories/about_secunia_advisories/\n\n\nPlease Note:\nSecunia recommends that you verify all advisories you receive by\nclicking the link. \nSecunia NEVER sends attached files with advisories. \nSecunia does not advise people to install third party patches, only\nuse those supplied by the vendor. \n\n----------------------------------------------------------------------\n\nUnsubscribe: Secunia Security Advisories\nhttp://secunia.com/sec_adv_unsubscribe/?email=packet%40packetstormsecurity.org\n\n----------------------------------------------------------------------\n\n\n",
