Motorola MR2600 Router Vulnerable to Unauthenticated RCE Attack
Key points
- Router firmware version 1.0.22 revealed unauthenticated RCE vulnerability.
- Attackers can upload malicious firmware via a flawed POST endpoint.
- Vulnerability poses serious risks for device security and user safety.
Discovery of Vulnerability
An unauthenticated remote code execution (RCE) vulnerability was identified in Motorola’s MR2600 router. The discovery came during an investigation into various router vendors, and the MR2600 was found to have a significant security fault in its firmware process.
How the Vulnerability Works
The MR2600 router does not publicly distribute firmware, opting for over-the-air updates. However, the last firmware version (v1.0.22) was accessible for analysis. The flaw lies in the router's update procedure, which was designed to authenticate updates but failed to enforce proper validation.
Technical Flaw in Firmware Update Process
When an update is initiated via the '/WEBCGI1/prog.fcgi?method=/cgi-bin/fwupload.cgi' POST endpoint, the router checks for specific magic numbers in the firmware file. However, due to poor implementation, an attacker can upload a malicious firmware image as raw data, bypassing the authentication check.
Implications of the Vulnerability
This flaw allows unauthenticated users to potentially take control of the router by uploading custom firmware, creating severe security vulnerabilities for users. The incident highlights the importance of robust security measures in device firmware updates.
