Root command execution via crafted TDDP packet
Published Sep 10, 2026 · Updated Sep 10, 2026
OS command injection in the TDDP module in TP-Link Deco BE11000 before 1.3.5 Build 26071712 allows attackers to execute root commands. The TDDP UDP packet handler treats attacker-controlled packet content as operating-system command input without neutralizing command syntax. Exploitation requires adjacent-network access and can modify device settings or compromise data and service availability under root privileges.
