The flaw stems from improper input handling in the EVENT=CHECKFW parameter, which is passed directly to the system shell without sanitization. A crafted HTTP POST request can inject commands that are executed with root privileges, resulting in full device compromise. These router models are no longer supported at the time of assignment and affected version ranges may vary. Exploitation evidence was first observed by the Shadowserver Foundation on 2025-08-21 UTC.","provenance":"source","from":"CVE.org"},"summary":{"text":"A command injection flaw in the service.cgi endpoint of several discontinued D-Link DIR-series routers (including DIR-110, DIR-412, DIR-600, DIR-615, DIR-645, DIR-815 and others, firmware 1.03) allows unsanitised input in the EVENT=CHECKFW parameter to reach the system shell. An unauthenticated remote attacker with network access can send a crafted HTTP POST request to execute arbitrary system commands as root, fully compromising the device without any user interaction.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-31T12:59:47Z"},"cvss":{"score":10,"severity":"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:H/SI:H/SA:H","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.10409,"percentile":0.95725,"date":"2026-10-30","provenance":"source"},"kev":null,"vulncheckKev":{"dateAdded":"2023-09-06","exploitedFirstSeen":"2023-09-06","ransomware":false,"evidence":[{"url":"https://www.vulncheck.com/advisories/dlink-dir-rce-service-cgi","date":"2023-09-06"},{"url":"https://www.cve.org/cverecord?id=CVE-2018-25115","date":"2025-08-21"}],"evidenceTotal":2,"provenance":"source"},"exploited":true,"otx":{"pulseCount":0,"pulses":[],"provenance":"machine"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"references":[{"url":"https://github.com/Cr0n1c/dlink_shell_poc/blob/master/dlink_auth_rce","tags":["technical-description","exploit"]},{"url":"https://www.exploit-db.com/exploits/43496","tags":["exploit"]},{"url":"https://legacy.us.dlink.com/","tags":["product"]},{"url":"https://support.dlink.com/EndOfLifePolicy.aspx","tags":["product"]},{"url":"https://www.vulncheck.com/advisories/dlink-dir-rce-service-cgi","tags":["third-party-advisory"]}],"techniques":[],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2018-21602","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2018-21602","exploited":false,"exploitedSince":null,"provenance":"source"},"exploits":[],"exploitSources":null,"exploitRefs":["https://github.com/Cr0n1c/dlink_shell_poc/blob/master/dlink_auth_rce","https://www.exploit-db.com/exploits/43496"],"flow":[],"timeline":[{"date":"2023-09-06","kind":"exploited-reported","label":"Exploitation first reported (VulnCheck KEV evidence)","url":"https://www.vulncheck.com/advisories/dlink-dir-rce-service-cgi","provenance":"source"},{"date":"2025-08-27","kind":"published","label":"Published (CVE.org)","url":"https://www.cve.org/CVERecord?id=CVE-2018-25115","provenance":"source"}],"speed":{"daysToPublicExploit":null,"firstExploitFrom":null,"daysToKev":null},"priority":{"score":66.1,"factors":[{"name":"In a KEV catalog","points":35.0,"detail":"listed in VulnCheck KEV"},{"name":"Recent KEV listing","points":0.0,"detail":"added 1151 days ago"},{"name":"Known ransomware use","points":0.0,"detail":"not known"},{"name":"EPSS percentile","points":19.14,"detail":"percentile 0.9573"},{"name":"Named in threat reports","points":0.0,"detail":"0 reports"},{"name":"Public exploit code","points":5.0,"detail":"2 NVD references tagged Exploit"},{"name":"Mentioned in OTX pulses","points":0.0,"detail":"0 pulses"},{"name":"CVSS severity","points":7.0,"detail":"base score 10"},{"name":"End-of-life product","points":0.0,"detail":"supported or unknown"}]}}
