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.","cvssScore":9.1,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","cwes":["CWE-119","CWE-121"],"vendors":[],"products":[],"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":[]}],"exploitRefs":[{"url":"https://github.com/ZaneBoden/CVEs/blob/main/Tenda-AC9-fast_setting_internet_set.md","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw is a stack-based buffer overflow in the Tenda AC9 firmware, allowing remote attackers to exploit it by manipulating the netWanType argument.
