CVE-2026-15427Network attack vector

Root command execution via unsanitized CWMP parameters

Published Jul 14, 2026 · Updated Jul 14, 2026

The interface passes insufficiently validated and sanitized parameters from ACS-delivered commands to the system command interpreter. TR-069 must be enabled, and the attacker must influence commands delivered by, compromise, or control the configured ACS server.
