CVE-2023-0776Network attack vector

Unauthenticated root command execution via HTTP injection

Published Feb 10, 2023 · Updated Mar 24, 2025

Command injection in Baicells QRTB firmware 2.12.7 and earlier allows remote attackers to execute shell commands as root over HTTP. The pre-login HTTP request handling path passes attacker-controlled command elements to a shell without adequate neutralization. No authentication or user interaction is required, and successful exploitation grants full root-level control of the eNodeB.
