Affected is an unknown function of the file /goform/fast_setting_internet_set of the component POST Request Handler. Performing a manipulation of the argument netWanType results in stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit is now public and may be used.","provenance":"source","from":"NVD"},"summary":{"text":"A stack-based buffer overflow in the POST Request Handler component of the Tenda AC9 router running firmware 15.03.02.13, specifically in the handling of the netWanType argument to /goform/fast_setting_internet_set. An attacker with remote network access can trigger the overflow by manipulating that argument, though the attack requires high privileges (PR:H) and no user interaction.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-23T07:18:47Z"},"cvss":{"score":9.1,"severity":"CRITICAL","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","provenance":"source","from":"NVD"},"epss":{"score":0.00493,"percentile":0.42265,"date":"2026-10-29","provenance":"source"},"kev":null,"vulncheckKev":null,"exploited":false,"otx":{"pulseCount":5,"pulses":[{"name":"Known_Cve | Oct 11, 2026 | Part 1/2","url":"https://otx.alienvault.com/pulse/6aca554665c47eb24716f8f2","created":"2026-10-10"},{"name":"Known_Cve | Oct 10, 2026 | Part 1/2","url":"https://otx.alienvault.com/pulse/6ac903591ff588ac9423f235","created":"2026-10-09"},{"name":"Known_Cve | Oct 9, 2026 | Part 1/2","url":"https://otx.alienvault.com/pulse/6ac7b19da11e545ded10ae9b","created":"2026-10-08"},{"name":"Known_Cve | Oct 8, 2026 | Part 1/2","url":"https://otx.alienvault.com/pulse/6ac65e541c36819c31053833","created":"2026-10-07"},{"name":"Known_Cve | Oct 7, 2026 | Part 2/2","url":"https://otx.alienvault.com/pulse/6ac50f851d74c73e484f44c6","created":"2026-10-06"}],"provenance":"machine"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"references":[{"url":"https://github.com/ZaneBoden/CVEs/blob/main/Tenda-AC9-fast_setting_internet_set.md","tags":[]},{"url":"https://vuldb.com/cve/CVE-2026-104611","tags":[]},{"url":"https://vuldb.com/submit/962720","tags":[]},{"url":"https://vuldb.com/vuln/412918","tags":[]},{"url":"https://vuldb.com/vuln/412918/cti","tags":[]},{"url":"https://www.tenda.com.cn/","tags":[]}],"techniques":[],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2026-91579","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-91579","exploited":false,"exploitedSince":null,"provenance":"source"},"exploits":[],"exploitSources":null,"exploitRefs":[],"flow":[],"timeline":[{"date":"2026-10-02","kind":"published","label":"Published (NVD)","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104611","provenance":"source"}],"speed":{"daysToPublicExploit":null,"firstExploitFrom":null,"daysToKev":null},"priority":{"score":16.6,"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":8.45,"detail":"percentile 0.4227"},{"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":1.77,"detail":"5 pulses"},{"name":"CVSS severity","points":6.37,"detail":"base score 9.1"},{"name":"End-of-life product","points":0.0,"detail":"supported or unknown"}]}}
