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.

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 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.

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.

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.

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 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.

Sierra Wireless MGOS before 3.15.2 and 4.x before 4.3 allows attackers to read log files via a Direct Request (aka Forced Browsing).

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 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.

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

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.

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.

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 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.

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.

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.

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

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

A stack overflow vulnerabiltity exists in the AT command APIs of ALEOS before 4.11.0. The vulnerability may allow code execution.

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

A stack overflow vulnerabiltity exist in the AT command interface of ALEOS before 4.11.0. The vulnerability may allow code execution

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.

The Sierra Wireless AirLink Raven X EV-DO gateway 42214.0.11.003 and 42284.0.11.003 allows remote attackers to reprogram the firmware via a replay attack using UDP ports 17336 and 17388.

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.

ACEmanager in Sierra Wireless ALEOS 4.4.2 and earlier on ES440, ES450, GX400, GX440, GX450, and LS300 devices allows remote attackers to read the filteredlogs.txt file, and consequently discover potentially sensitive boot-sequence information, via unspecified vectors.

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.

Sierra Wireless GX 440 devices with ALEOS firmware 4.3.2 have weak passwords for admin, rauser, sconsole, and user.
