{"id":"CVE-2026-101354","published":"2026-09-29T02:16:53.230","lastModified":"2026-09-29T18:57:24.350","description":"A security flaw has been discovered in FAST FAC1203R 20200116_2.0.4. The affected element is the function _tWlanTask of the component MmtAtePrase Parser. Performing a manipulation results in stack-based buffer overflow. The attacker must have access to the local network to execute the attack. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.","cvssScore":9.6,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","cwes":["CWE-119","CWE-121"],"vendors":[],"products":[],"references":[{"url":"https://github.com/xiaobor123/vuls-find-VxWorks/tree/main/vul-find-FAST_FAC1203R-twlantask-MmtAtePrase-stack-overflow(1)/vul-find-FAST_FAC1203R-twlantask-MmtAtePrase-stack-overflow","tags":[]},{"url":"https://vuldb.com/cve/CVE-2026-101354","tags":[]},{"url":"https://vuldb.com/submit/927238","tags":[]},{"url":"https://vuldb.com/vuln/411088","tags":[]},{"url":"https://vuldb.com/vuln/411088/cti","tags":[]}],"exploitRefs":[{"url":"https://github.com/xiaobor123/vuls-find-VxWorks/tree/main/vul-find-FAST_FAC1203R-twlantask-MmtAtePrase-stack-overflow(1)/vul-find-FAST_FAC1203R-twlantask-MmtAtePrase-stack-overflow","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw is a stack-based buffer overflow in the _tWlanTask function of the MmtAtePrase Parser component, allowing local network attackers to execute arbitrary code.
