{"apiVersion":"1.0","identifier":"CVE-2026-71937","description":"Multiple DrayTek VigorSwitch models contain a buffer overflow vulnerability in the poe_schedule_profile function. The vulnerability is caused by repeated concatenation of the start_date, start_time, duration_time, how_often, weekdays, monthly_date, and cycle_duration fields into small fixed-size buffers without proper length checks. A remote attacker can trigger this vulnerability via crafted input, causing a denial of service or potentially executing arbitrary commands. Exploitation requires valid administrative credentials for the device-s web management interface.","publishedAt":"2026-08-24T18:17:18","lastModifiedAt":"2026-08-26T17:08:22","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-71937","cvssScore":7.2,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00478,"riskScore":0.75,"affectedProduct":"DrayTek VigorSwitch","affectedVersions":"unknown","vulnerabilityType":"Firmware","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-71937","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-71937","en":"https://www.redsauce.net/en/cves/CVE-2026-71937","fr":"https://www.redsauce.net/fr/cves/CVE-2026-71937","pt":"https://www.redsauce.net/pt/cves/CVE-2026-71937","de":"https://www.redsauce.net/de/cves/CVE-2026-71937","sk":"https://www.redsauce.net/sk/cves/CVE-2026-71937","el":"https://www.redsauce.net/el/cves/CVE-2026-71937"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-71937"}}
