Soumettre #1044957: DrayTek Vigor2960 Vigor2960 1.5.1.6 (revision 8218) Authenticated swmconfigupload Field-Name Command Injection

swmconfigupload inserts the attacker-controlled multipart field name directly into a single-quoted shell logging command. A malicious field name can terminate the quoted context and append commands. The current PoC confirms an interactive reverse shell on the real device.

Affected interface: POST /cgi-bin/mainfunction.cgi/swmconfigupload
Attacker-controlled input: multipart field name
Confirmed impact: an authenticated attacker can execute arbitrary shell commands and obtain a reverse shell.
