An information disclosure vulnerability exists in the ACEManager authentication functionality of Sierra Wireless AirLink ES450 FW 4.9.3. The ACEManager authentication functionality is done in plaintext XML to the web server. An attacker can listen to network traffic upstream from the device to capitalize on this vulnerability.

An exploitable information disclosure vulnerability exists in the ACEManager functionality of Sierra Wireless AirLink ES450 FW 4.9.3. A HTTP request can result in disclosure of the default configuration for the device. An attacker can send an unauthenticated HTTP request to trigger this vulnerability.

An exploitable command injection vulnerability exists in the ACEManager iplogging.cgi functionality of Sierra Wireless AirLink ES450 FW 4.9.3. A specially crafted HTTP request can inject arbitrary commands, resulting in arbitrary command execution. An attacker can send an authenticated HTTP request to trigger this vulnerability.

A vulnerability in Sierra Wireless AirLink GX400, GX440, ES440, and LS300 routers with firmware before 4.4.5 and GX450, ES450, RV50, RV50X, MP70, and MP70E routers with firmware before 4.9 could allow an authenticated remote attacker to execute arbitrary code and gain full control of an affected system, including issuing commands with root privileges. This vulnerability is due to insufficient input validation on user-controlled input in an HTTP request to the targeted device. An attacker in possession of router login credentials could exploit this vulnerability by sending a crafted HTTP request to an affected system.
