Vulnerability from variot

The CmpWebServer.dll module in the Control service in 3S CoDeSys 3.4 SP4 Patch 2 allows remote attackers to cause a denial of service (NULL pointer dereference) via (1) a crafted Content-Length in an HTTP POST or (2) an invalid HTTP request method. CoDeSys Automation Suite is a comprehensive software tool for industrial automation technology. CoDeSys has multiple remote denial of service vulnerabilities in its implementation, which can be exploited by remote attackers to crash applications and deny legitimate users. A vulnerability exists in the CmpWebServer.dll module in the Control service in the 3S CoDeSys 3.4 SP4 Patch 2 release. CoDeSys is prone to multiple denial-of-service vulnerabilities. ----------------------------------------------------------------------

DESCRIPTION: Luigi Auriemma has discovered multiple vulnerabilities in CoDeSys, which can be exploited by malicious people to cause a DoS (Denial of Service) and compromise a vulnerable system.

1) An integer overflow error in the Gateway service when processing certain requests can be exploited to cause a heap-based buffer overflow via a specially crafted packet sent to TCP port 1217.

2) A boundary error in the Control service when processing web requests can be exploited to cause a stack-based buffer overflow via an overly long URL sent to TCP port 8080.

5) An error in the Control service when processing web requests containing a non-existent directory can be exploited to create arbitrary directories within the webroot via requests sent to TCP port 8080.

Successful exploitation of vulnerabilities #1 and #2 allows execution of arbitrary code.

The vulnerabilities are confirmed in version 3.4 SP4 Patch 2. Other versions may also be affected.

SOLUTION: Restrict access to trusted hosts only.

    "data": "The CmpWebServer.dll module in the Control service in 3S CoDeSys 3.4 SP4 Patch 2 allows remote attackers to cause a denial of service (NULL pointer dereference) via (1) a crafted Content-Length in an HTTP POST or (2) an invalid HTTP request method. CoDeSys Automation Suite is a comprehensive software tool for industrial automation technology. CoDeSys has multiple remote denial of service vulnerabilities in its implementation, which can be exploited by remote attackers to crash applications and deny legitimate users. A vulnerability exists in the CmpWebServer.dll module in the Control service in the 3S CoDeSys 3.4 SP4 Patch 2 release. CoDeSys is prone to multiple denial-of-service vulnerabilities. ----------------------------------------------------------------------\n\nSecunia is hiring!\n\nFind your next job here:\n\nhttp://secunia.com/company/jobs/\n\n----------------------------------------------------------------------\n\nTITLE:\nCoDeSys Multiple Vulnerabilities\n\nSECUNIA ADVISORY ID:\nSA47018\n\nVERIFY ADVISORY:\nSecunia.com\nhttp://secunia.com/advisories/47018/\nCustomer Area (Credentials Required)\nhttps://ca.secunia.com/?page=viewadvisory\u0026vuln_id=47018\n\nRELEASE DATE:\n2011-12-01\n\nDISCUSS ADVISORY:\nhttp://secunia.com/advisories/47018/#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/47018/\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=47018\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:\nLuigi Auriemma has discovered multiple vulnerabilities in CoDeSys,\nwhich can be exploited by malicious people to cause a DoS (Denial of\nService) and compromise a vulnerable system. \n\n1) An integer overflow error in the Gateway service when processing\ncertain requests can be exploited to cause a heap-based buffer\noverflow via a specially crafted packet sent to TCP port 1217. \n\n2) A boundary error in the Control service when processing web\nrequests can be exploited to cause a stack-based buffer overflow via\nan overly long URL sent to TCP port 8080. \n\n5) An error in the Control service when processing web requests\ncontaining a non-existent directory can be exploited to create\narbitrary directories within the webroot via requests sent to TCP\nport 8080. \n\nSuccessful exploitation of vulnerabilities #1 and #2 allows execution\nof arbitrary code. \n\nThe vulnerabilities are confirmed in version 3.4 SP4 Patch 2. Other\nversions may also be affected. \n\nSOLUTION:\nRestrict access to trusted hosts only. \n\nPROVIDED AND/OR DISCOVERED BY:\nLuigi Auriemma\n\nORIGINAL ADVISORY:\nhttp://aluigi.altervista.org/adv/codesys_1-adv.txt\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",
