The vulnerability is due to the presence of certain test commands that were intended to be available only in internal development builds of the affected software. An attacker could exploit this vulnerability by using these commands on an affected device. A successful exploit could allow the attacker to write arbitrary values to arbitrary locations in the memory space of the affected device.","provenance":"source","from":"CVE.org"},"summary":null,"cvss":null,"epss":{"score":0.00327,"percentile":0.25666,"date":"2026-10-28","provenance":"source"},"kev":null,"vulncheckKev":null,"exploited":false,"otx":{"pulseCount":0,"pulses":[],"provenance":"machine"},"cwes":[{"id":"CWE-123","name":"Write-what-where Condition"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-ir800-memwrite","tags":["vendor-advisory","x_refsource_CISCO"]}],"techniques":[{"id":"T1091","name":"Replication Through Removable Media","tactics":["initial-access","lateral-movement"],"provenance":"source","basis":"ctid-cve","bases":["ctid-cve"],"basisDetail":"CTID attack_to_cve (Phase 2)","mappingType":"exploitation_technique","evidence":[],"confidence":"low","confidenceNote":"Windows-only technique on a non-Windows product"},{"id":"T1204.002","name":"Malicious File","tactics":["execution"],"provenance":"source","basis":"ctid-cve","bases":["ctid-cve"],"basisDetail":"CTID attack_to_cve (Phase 2)","mappingType":"exploitation_technique","evidence":[],"confidence":"high"},{"id":"T1566","name":"Phishing","tactics":["initial-access"],"provenance":"source","basis":"ctid-cve","bases":["ctid-cve"],"basisDetail":"CTID attack_to_cve (Phase 2)","mappingType":"exploitation_technique","evidence":[],"confidence":"high"},{"id":"T1499.004","name":"Application or System Exploitation","tactics":["impact"],"provenance":"source","basis":"ctid-cve","bases":["ctid-cve"],"basisDetail":"CTID attack_to_cve (Phase 2)","mappingType":"primary_impact","evidence":[],"confidence":"high"},{"id":"T1574","name":"Hijack Execution Flow","tactics":["execution","stealth"],"provenance":"source","basis":"ctid-cve","bases":["ctid-cve"],"basisDetail":"CTID attack_to_cve (Phase 2)","mappingType":"primary_impact","evidence":[],"confidence":"high"}],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2018-7254","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2018-7254","exploited":false,"exploitedSince":null,"provenance":"source"},"exploits":[],"exploitSources":null,"exploitRefs":[],"flow":[{"stage":"exploitation","techniques":["T1566","T1204.002"],"provenance":"source"},{"stage":"primary","techniques":["T1574","T1499.004"],"provenance":"source"},{"stage":"related","techniques":["T1091"],"provenance":"source","lowConfidence":true}],"timeline":[{"date":"2018-10-05","kind":"published","label":"Published (CVE.org)","url":"https://www.cve.org/CVERecord?id=CVE-2018-15376","provenance":"source"}],"speed":{"daysToPublicExploit":null,"firstExploitFrom":null,"daysToKev":null},"priority":{"score":5.1,"factors":[{"name":"In a KEV catalog","points":0.0,"detail":"not listed"},{"name":"Recent KEV listing","points":0.0,"detail":"not listed"},{"name":"Known ransomware use","points":0.0,"detail":"not known"},{"name":"EPSS percentile","points":5.13,"detail":"percentile 0.2567"},{"name":"Named in threat reports","points":0.0,"detail":"0 reports"},{"name":"Public exploit code","points":0.0,"detail":"none found"},{"name":"Mentioned in OTX pulses","points":0.0,"detail":"0 pulses"},{"name":"CVSS severity","points":0.0,"detail":"no CVSS"},{"name":"End-of-life product","points":0.0,"detail":"supported or unknown"}]}}
