This impacts the function getDeviceInfo of the file /var/lib/misc/udhcpd.leases of the component device-information Handler. The manipulation of the argument MAC address results in command injection. The attack can be launched remotely. The exploit has been made public and could be used.","provenance":"source","from":"NVD"},"summary":{"text":"A command injection flaw exists in the getDeviceInfo function of the device-information handler in the TOTOLINK A950RG (firmware 4.1.2cu.5268_B20221104), where the MAC address argument is processed from /var/lib/misc/udhcpd.leases. An attacker who can reach the device over the network and holds high-privilege credentials can manipulate that MAC address value to inject and run arbitrary commands on the device, with impact on confidentiality, integrity and availability.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-29T07:22:21Z"},"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":0.02741,"percentile":0.86149,"date":"2026-10-30","provenance":"source"},"kev":null,"vulncheckKev":null,"exploited":false,"otx":{"pulseCount":4,"pulses":[{"name":"Known_Cve | Oct 31, 2026 | Part 1/3","url":"https://otx.alienvault.com/pulse/6ae4af0017a739f65534f550","created":"2026-10-30"},{"name":"Known_Cve | Oct 30, 2026 | Part 2/2","url":"https://otx.alienvault.com/pulse/6ae35d945cba1d70e2bf3a79","created":"2026-10-29"},{"name":"Known_Cve | Oct 29, 2026 | Part 3/3","url":"https://otx.alienvault.com/pulse/6ae20c338ef6b2d900217a8b","created":"2026-10-28"},{"name":"Known_Cve | Oct 28, 2026 | Part 3/3","url":"https://otx.alienvault.com/pulse/6ae0ba957a5b2456c9113c92","created":"2026-10-27"}],"provenance":"machine"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"},{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"references":[{"url":"https://gist.github.com/H3rmesk1t/836a8c4be24fcc4b7041b4bbe9cbb178","tags":[]},{"url":"https://vuldb.com/cve/CVE-2026-116505","tags":[]},{"url":"https://vuldb.com/submit/1022554","tags":[]},{"url":"https://vuldb.com/vuln/426403","tags":[]},{"url":"https://vuldb.com/vuln/426403/cti","tags":[]},{"url":"https://www.totolink.net/","tags":[]}],"techniques":[],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2026-110448","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-110448","exploited":false,"exploitedSince":null,"provenance":"source"},"exploits":[],"exploitSources":null,"exploitRefs":[],"flow":[],"timeline":[{"date":"2026-10-26","kind":"published","label":"Published (NVD)","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-116505","provenance":"source"}],"speed":{"daysToPublicExploit":null,"firstExploitFrom":null,"daysToKev":null},"priority":{"score":25.2,"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":17.23,"detail":"percentile 0.8615"},{"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":1.59,"detail":"4 pulses"},{"name":"CVSS severity","points":6.37,"detail":"base score 9.1"},{"name":"End-of-life product","points":0.0,"detail":"supported or unknown"}]}}
