{"id":"CVE-2009-20005","state":"PUBLISHED","title":"InterSystems Caché UtilConfigHome.csp Stack Buffer Overflow","description":"A stack-based buffer overflow exists in the UtilConfigHome.csp endpoint of InterSystems Caché 2009.1. The vulnerability is triggered by sending a specially crafted HTTP GET request containing an oversized argument to the .csp handler. Due to insufficient bounds checking, the input overflows a stack buffer, allowing an attacker to overwrite control structures and execute arbitrary code. It is unknown if this vulnerability was patched and an affected version range remains undefined.","publishedAt":"2025-09-16T14:32:00.691Z","updatedAt":"2026-05-15T11:13:15.114Z","severity":{"score":9.3,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["InterSystems Corporation InterSystems Caché"],"affected":[{"vendor":"InterSystems Corporation","product":"InterSystems Caché","defaultStatus":"unknown","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2009.1","versionType":"custom"}],"modules":["/csp/sys/mgr/UtilConfigHome.csp"]}],"references":["https://raw.githubusercontent.com/rapid7/metasploit-framework/master/modules/exploits/windows/http/intersystems_cache.rb","https://www.exploit-db.com/exploits/16807","https://www.juniper.net/us/en/threatlabs/ips-signatures/detail.APP:INTERSYSTEMS-CACHE-OF.html","https://www.intersystems.com/products/cache/","https://www.vulncheck.com/advisories/intersystems-cache-stack-buffer-overflow"],"weaknesses":["CWE-121"],"ingestedAt":"2026-10-29T19:39:18.559Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2009/20xxx/CVE-2009-20005.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2009-20005","state":"PUBLISHED","datePublished":"2025-09-16T14:32:00.691Z","dateUpdated":"2026-05-15T11:13:15.114Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2025-08-27T18:34:34.963Z"},"containers":{"cna":{"title":"InterSystems Caché UtilConfigHome.csp Stack Buffer Overflow","descriptions":[{"lang":"en","value":"A stack-based buffer overflow exists in the UtilConfigHome.csp endpoint of InterSystems Caché 2009.1.
