The custom shellinaboxd builds its SSH connection target using a snprintf call with user-supplied input; by supplying an overlong username string an attacker causes the device IP suffix to be truncated, redirecting the resulting connection to an arbitrary host. Attackers can use this capability to enumerate or communicate with internal network endpoints that would otherwise be inaccessible.","published":"2026-09-22T16:18:01.000Z","lastModified":"2026-09-26T14:16:59.000Z","status":"Awaiting Analysis","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":7.7,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:H/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-918"],"affected":[],"epss":{"score":0.0058,"percentile":0.4742,"date":"2026-10-26","history":[{"date":"2026-09-23","score":0.00541,"percentile":0.44428}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.58%).
