Exploitation Summary

EIP tracks 5 public exploits for CVE-2017-5255. PoCs published by Metasploit, including Metasploit module auxiliary/scanner/http/epmp1000_ping_cmd_exec.

AI-analyzed exploit summary This Metasploit module exploits an OS command injection vulnerability in Cambium ePMP1000 device management portal via the 'get_chart' endpoint. It authenticates using default credentials and injects a reverse shell payload.

Description

In version 3.5 and prior of Cambium Networks ePMP firmware, a lack of input sanitation for certain parameters on the web management console allows any authenticated user (including the otherwise low-privilege readonly user) to inject shell meta-characters as part of a specially-crafted POST request to the get_chart function and run OS-level commands, effectively as root.
