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.

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.

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.

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

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.

A vulnerability in Sierra Wireless AirLink GX400, GX440, ES440, and LS300 routers with firmware before 4.4.7 and GX450, ES450, RV50, RV50X, MP70, and MP70E routers with firmware before 4.9.3 could allow an unauthenticated remote attacker to execute arbitrary code and gain full control of an affected system, including issuing commands with root privileges.

An exploitable unverified password change vulnerability exists in the ACEManager upload.cgi functionality of Sierra Wireless AirLink ES450 FW 4.9.3. A specially crafted HTTP request can cause a unverified device configuration change, resulting in an unverified change of the user password on the device. An attacker can make an authenticated HTTP request 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 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.

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 cross-site scripting vulnerability exists in the ACEManager pingresult.cgi functionality of Sierra Wireless AirLink ES450 FW 4.9.3. A specially crafted HTTP ping request can cause reflected javascript code execution, resulting in the execution of javascript code running on the victim's browser. An attacker can get a victim to click a link, or embedded URL, that redirects to the reflected cross-site scripting vulnerability 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.

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

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.
