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.

Sierra Wireless ALEOS before 4.4.2 on AirLink ES, GX, and LS devices has hardcoded root accounts, which makes it easier for remote attackers to obtain administrative access via a (1) SSH or (2) TELNET session.

ALEOS LAN-Side RPC Service Remote Code Execution

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

Lack of input sanitization in UpdateRebootMgr service of ALEOS 4.11 and later allow an escalation to root from a low-privilege process.

ALEOS SSH Service Allows Traffic Proxying

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

ALEOS SMS Handler Buffer Overflow

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.

ALEOS Multiple Web UI vulnerabilities

Multiple buffer overflow vulnerabilities exist in the AceManager Web API of ALEOS before 4.13.0, 4.9.5, and 4.4.9.

ALEOS AceManager Information Disclosure

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.

ALEOS ACEView Message Replay

A nonce reuse vulnerability exists in the ACEView service of ALEOS before 4.13.0, 4.9.5, and 4.4.9 allowing message replay. Captured traffic to the ACEView service can be replayed to other gateways sharing the same credentials.

ALEOS LAN-Side RPC Server

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.

ALEOS AT Command Injections

Several potential command injections vulnerabilities exist in the AT command interface of ALEOS before 4.11.0, and 4.9.4.

ALEOS ACEView Service Out-Of-Bounds Read

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.

ALEOS AT Command API Abuse

An API abuse vulnerability exists in the AT command API of ALEOS before 4.13.0, 4.9.5, 4.4.9 due to lack of length checking when handling certain user-provided values.

ALEOS User Root Shell Escalation

An improper privilege management vulnerabitlity exists in ALEOS before 4.11.0, 4.9.4 and 4.4.9. An authenticated user can escalate to root via the command shell.

An exploitable Permission Assignment vulnerability exists in the ACEManager EmbeddedAceSet_Task.cgi functionality of Sierra Wireless AirLink ES450 FW 4.9.3. The the binary the endpoint /cgi-bin/Embeded_Ace_TLSet_Task.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 Permission Assignment vulnerability exists in the ACEManager EmbeddedAceSet_Task.cgi functionality of Sierra Wireless AirLink ES450 FW 4.9.3. The EmbeddedAceSet_Task.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/Embedded_Ace_Set_Task.cgi endpoint.

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.

An exploitable Information Disclosure vulnerability exists in the ACEManager EmbeddedAceGet_Task.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/Embedded_Ace_Get_Task.cgi endpoint.

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.
