Affected by this issue is the function sub_182B0 of the file /cgi-bin/mainfunction.cgi of the component CGI Interface. This manipulation of the argument usefile/usescript/option causes os command injection. Remote exploitation of the attack is possible. The exploit has been published and may be used. The vendor explains: \"2960 1.5.1.7 has corrected many security issues. And 2960 is EoS with limited support, only major issues would be reviewed(e.g. unauthenticated vuln.)\". This vulnerability only affects products that are no longer supported by the maintainer.","provenance":"source","from":"NVD"},"summary":{"text":"A flaw in the CGI Interface component of DrayTek Vigor2960 version 1.5.1.6 Revision 8218 lies in the function sub_182B0 within /cgi-bin/mainfunction.cgi, where manipulation of the usefile, usescript, and option arguments enables OS command injection. Remote exploitation is possible over the network with low attack complexity, and the attacker requires low privileges (an authenticated account) with no user interaction needed, while the vendor notes the product is end-of-support and affected by this issue only in unsupported releases.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-23T07:16:04Z"},"cvss":{"score":9.9,"severity":"CRITICAL","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","provenance":"source","from":"NVD"},"epss":{"score":0.01863,"percentile":0.79243,"date":"2026-10-30","provenance":"source"},"kev":null,"vulncheckKev":null,"exploited":false,"otx":{"pulseCount":6,"pulses":[{"name":"Known_Cve | Oct 29, 2026 | Part 1/3","url":"https://otx.alienvault.com/pulse/6ae20c23cd267c7cddd4e545","created":"2026-10-28"},{"name":"Known_Cve | Oct 28, 2026 | Part 1/3","url":"https://otx.alienvault.com/pulse/6ae0ba88997d8920e9952075","created":"2026-10-27"},{"name":"Known_Cve | Oct 27, 2026 | Part 1/3","url":"https://otx.alienvault.com/pulse/6adf68beabc3bad24a2b7cc6","created":"2026-10-26"},{"name":"Known_Cve | Oct 24, 2026 | Part 2/3","url":"https://otx.alienvault.com/pulse/6adb741adaae4be68dd04fea","created":"2026-10-23"},{"name":"Known_Cve | Oct 23, 2026 | Part 2/3","url":"https://otx.alienvault.com/pulse/6ada237de8198eb6a6cbfac4","created":"2026-10-22"},{"name":"Known_Cve | Oct 22, 2026 | Part 3/4","url":"https://otx.alienvault.com/pulse/6ad8d34cb141a6cceeba88be","created":"2026-10-21"}],"provenance":"machine"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"},{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"references":[{"url":"https://github.com/yikesoftware/DrayTek_Vigor2960_Security_Analysis/tree/main/cases/DRV2960-0007-authenticated-jsonstatus-usefile-file-clobber","tags":[]},{"url":"https://vuldb.com/cve/CVE-2026-113390","tags":[]},{"url":"https://vuldb.com/submit/992224","tags":[]},{"url":"https://vuldb.com/vuln/422666","tags":[]},{"url":"https://vuldb.com/vuln/422666/cti","tags":[]}],"techniques":[],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2026-104988","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-104988","exploited":false,"exploitedSince":null,"provenance":"source"},"exploits":[],"exploitSources":null,"exploitRefs":[],"flow":[],"timeline":[{"date":"2026-10-20","kind":"published","label":"Published (NVD)","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-113390","provenance":"source"}],"speed":{"daysToPublicExploit":null,"firstExploitFrom":null,"daysToKev":null},"priority":{"score":24.7,"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":15.85,"detail":"percentile 0.7924"},{"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":1.92,"detail":"6 pulses"},{"name":"CVSS severity","points":6.93,"detail":"base score 9.9"},{"name":"End-of-life product","points":0.0,"detail":"supported or unknown"}]}}
