Unauthenticated RPC server on ALEOS before 4.4.9, 4.9.5, and 4.14.0 allows remote code execution.

An RPC server is enabled by default on the gateway's LAN of ALEOS before 4.12.0, 4.9.5, and 4.4.9.

The ACENet service in Sierra Wireless ALEOS before 4.4.9, 4.5.x through 4.9.x before 4.9.5, and 4.10.x through 4.13.x before 4.14.0 allows remote attackers to execute arbitrary code via a buffer overflow.

Sierra Wireless AirLink Mobility Manager (AMM) before 2.17 mishandles sessions and thus an unauthenticated attacker can obtain a login session with administrator privileges.

The Sierra Wireless AirLink Raven X EV-DO gateway 42214.0.11.003 and 42284.0.11.003 allows remote attackers to install Trojan horse firmware by leveraging cleartext credentials in a crafted (1) update or (2) reprogramming action.

A hard-coded credentials vulnerability exists in the snmpd function of the Sierra Wireless AirLink ES450 FW 4.9.3. Activating snmpd outside of the WebUI can cause the activation of the hard-coded credentials, resulting in the exposure of a privileged user. An attacker can activate snmpd without any configuration changes to trigger this vulnerability.

An out-of-bounds reads vulnerability exists in the ACEView Service of ALEOS before 4.13.0, 4.9.5, and 4.4.9. Sensitive information may be disclosed via the ACEviewservice, accessible by default on the LAN.

Lack of input sanitization in AceManager of ALEOS before 4.12.0, 4.9.5 and 4.4.9 allows disclosure of sensitive system information.

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.

Sierra Wireless GX 440 devices with ALEOS firmware 4.3.2 allow Hayes AT command injection.

A buffer overflow exists in the SMS handler API of ALEOS before 4.13.0, 4.9.5, 4.9.4 that may allow code execution as root.

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.

An exploitable cross-site request forgery vulnerability exists in the ACEManager functionality of Sierra Wireless AirLink ES450 FW 4.9.3. A specially crafted HTTP request can cause an authenticated user to perform privileged requests unknowingly, resulting in unauthenticated requests being requested through an authenticated user. An attacker can get an authenticated user to request authenticated pages on the attacker's behalf to trigger this vulnerability.

An exploitable Permission Assignment vulnerability exists in the ACEManager EmbeddedAceSetTask.cgi functionality of Sierra Wireless AirLink ES450 FW 4.9.3. The EmbeddedAceSetTask.cgi executable is used to change 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/EmbeddedAceSetTask.cgi endpoint.

An exploitable Permission Assignment vulnerability exists in the ACEManager EmbeddedAceSetTask.cgi functionality of Sierra Wireless AirLink ES450 FW 4.9.3. The the binary the endpoint /cgi-bin/EmbededAceTLSetTask.cgi is a very similar endpoint that is designed for use with setting table values that can cause an arbitrary setting writes, resulting in the unverified changes to any system setting. An attacker can make an authenticated HTTP request, or run the binary as any user, to trigger this vulnerability.

An exploitable Information Disclosure vulnerability exists in the ACEManager EmbeddedAceGetTask.cgi functionality of Sierra Wireless AirLink ES450 FW 4.9.3. The EmbeddedAceTLGetTask.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/EmbeddedAceTLGetTask.cgi endpoint.

An exploitable remote code execution vulnerability exists in the upload.cgi functionality of Sierra Wireless AirLink ES450 FW 4.9.3. A specially crafted HTTP request can upload a file, resulting in executable code being uploaded, and routable, to the webserver. An attacker can make an authenticated HTTP request to trigger this vulnerability.

An exploitable Information Disclosure vulnerability exists in the ACEManager EmbeddedAceGetTask.cgi functionality of Sierra Wireless AirLink ES450 FW 4.9.3. 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/EmbeddedAceGetTask.cgi endpoint.

Acemanager in ALEOS before version 4.16 allows a user with valid credentials to manipulate the IP logging operation to execute arbitrary shell commands on the device.

The SSH service on ALEOS before 4.12.0, 4.9.5, 4.4.9 allows traffic proxying.

Several versions of ALEOS, including ALEOS 4.16.0, include an opensource

third-party component which can be exploited from the local

area network, resulting in a Denial of Service condition for the captive portal.
