Summary

An exploitable Information Disclosure vulnerability exists in the ACEManager EmbeddedAceGet_Task.cgi functionality of Sierra Wireless AirLink ES450 FW 4.9.3. The EmbeddedAceTLGet_Task.cgi executable is used to retrieve MSCII configuration values within the configuration manager of the AirLink ES450. This binary does not have any restricted configuration settings, so once the MSCIID is discovered, any authenticated user can send configuration changes using the /cgi-bin/Embedded_Ace_TLGet_Task.cgi endpoint.
