An attacker can send a valid ENIP SendRRData frame carrying a very short CIP payload whose path_size field claims that many more path words are present than are actually available. Because the parser trusts the attacker-controlled path_size and continues decoding path segments without a remaining-length boundary, it reads beyond the end of the stack receive buffer." } ], "affected": [ { "vendor": "n/a", "product": "n/a", "versions": [ { "version": "n/a", "status": "affected" } ] } ], "references": [ { "url": "https://github.com/EIPStackGroup/OpENer/issues/582" }, { "url": "https://gist.github.com/MrAlaskan/705c680856e48c535148265c0899ad4b" } ], "problemTypes": [ { "descriptions": [ { "type": "text", "lang": "en", "description": "n/a" } ] } ] }, "adp": [ { "problemTypes": [ { "descriptions": [ { "type": "CWE", "cweId": "CWE-125", "lang": "en", "description": "CWE-125 Out-of-bounds Read" } ] } ], "references": [ { "url": "https://github.com/EIPStackGroup/OpENer/issues/582", "tags": [ "exploit" ] } ], "metrics": [ { "cvssV3_1": { "scope": "UNCHANGED", "version": "3.1", "baseScore": 9.1, "attackVector": "NETWORK", "baseSeverity": "CRITICAL", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "NONE", "confidentialityImpact": "HIGH" } }, { "other": { "type": "ssvc", "content": { "timestamp": "2026-07-14T13:06:50.547479Z", "id": "CVE-2026-51541", "options": [ { "Exploitation": "poc" }, { "Automatable": "yes" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-07-14T13:06:54.526Z" } } ] }, "dataVersion": "5.2" }
