OpenNDS, as used in Sierra Wireless ALEOS before 4.17.0.12 and other products, allows remote attackers to cause a denial of service (NULL pointer dereference, daemon crash, and Captive Portal outage) via a GET request to /opennds_auth/ that lacks a custom query string parameter and client-token.

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.

Several versions of ALEOS, including ALEOS 4.16.0, use a hardcoded SSL certificate and private key. An attacker with access to these items could potentially perform a man in the middle attack between the ACEManager client and ACEManager server.

When configured in debugging mode by an authenticated user with administrative privileges, ALEOS 4.16 and earlier store the SHA512 hash of the common root password for that version in a directory accessible to a user with root privileges or equivalent access.

The ACEManager component of ALEOS 4.16 and earlier does not perform input sanitization during authentication, which could potentially result in a Denial of Service (DoS) condition for ACEManager without impairing other router functions. ACEManager recovers from the DoS condition by restarting within ten seconds of becoming unavailable.

The ACEManager component of ALEOS 4.16 and earlier allows an authenticated user with Administrator privileges to access a file upload field which does not fully validate the file name, creating a Stored Cross-Site Scripting condition.

The ACEManager component of ALEOS 4.16 and earlier does not validate uploaded file names and types, which could potentially allow an authenticated user to perform client-side script execution within ACEManager, altering the device functionality until the device is restarted.

The ACEManager component of ALEOS 4.16 and earlier does not adequately perform input sanitization during authentication, which could potentially result in a Denial of Service (DoS) condition for ACEManager without impairing other router functions. ACEManager recovers from the DoS condition by restarting within ten seconds of becoming unavailable.

Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability in Sierra Wireless, Inc ALEOS could potentially allow a remote attacker to trigger a Denial of Service (DoS) condition for ACEManager without impairing other router functions. This condition is cleared by restarting the device.

Acemanager in ALEOS before version 4.16 allows a user with valid credentials to reconfigure the device to expose the ACEManager credentials on the pre-login status page.

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 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.

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

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

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.

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

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.

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.

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.

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