CVE-2025-34125Public exploitNetwork attack vector

Unauthenticated command execution via crafted cookie values

Published Jul 16, 2025 · Updated Apr 7, 2026

Command injection in the lighttpd service of D-Link DSP-W110A1 1.05B01 allows remote attackers to execute Linux commands via cookies. The cookie handler passes backtick-delimited content from a single-letter cookie field to a shell without neutralizing command syntax. No authentication or user interaction is required, and successful execution grants control of the appliance; the vulnerable request accepts only short commands.
