An improper input sanitization vulnerability in the Motorola MR2600 router could allow a local user with elevated permissions to execute arbitrary code.

Improper access control of bootloader function was discovered in Motorola Mobility Motorola e20 prior to version RONS31.267-38-8 allows attacker with local access to read partition or RAM data.

The Motorola MOSCAD and ACE line of RTUs through 2022-05-02 omit an authentication requirement. They feature IP Gateway modules which allow for interfacing between Motorola Data Link Communication (MDLC) networks (potentially over a variety of serial, RF and/or Ethernet links) and TCP/IP networks. Communication with RTUs behind the gateway is done by means of the proprietary IPGW protocol (5001/TCP). This protocol does not have any authentication features, allowing any attacker capable of communicating with the port in question to invoke (a subset of) desired functionality.

The Motorola ACE1000 RTU through 2022-05-02 uses ECB encryption unsafely. It can communicate with an XRT LAN-to-radio gateway by means of an embedded client. Credentials for accessing this gateway are stored after being encrypted with the Tiny Encryption Algorithm (TEA) in ECB mode using a hardcoded key. Similarly, the ACE1000 RTU can route MDLC traffic over Extended Command and Management Protocol (XCMP) and Network Layer (XNL) networks via the MDLC driver. Authentication to the XNL port is protected by TEA in ECB mode using a hardcoded key.

The Motorola ACE1000 RTU through 2022-05-02 mishandles firmware integrity. It utilizes either the STS software suite or ACE1000 Easy Configurator for performing firmware updates. In case of the Easy Configurator, firmware updates are performed through access to the Web UI where file system, kernel, package, bundle, or application images can be installed. Firmware updates for the Front End Processor (FEP) module are performed via access to the SSH interface (22/TCP), where a .hex file image is transferred and a bootloader script invoked. File system, kernel, package, and bundle updates are supplied as RPM (RPM Package Manager) files while FEP updates are supplied as S-rec files. In all cases, firmware images were found to have no authentication (in the form of firmware signing) and only relied on insecure checksums for regular integrity checks.

The Motorola ACE1000 RTU through 2022-05-02 ships with a hardcoded SSH private key and initialization scripts (such as /etc/init.d/sshd_service) only generate a new key if no private-key file exists. Thus, this hardcoded key is likely to be used by default.

The Motorola ACE1000 RTU through 2022-05-02 has default credentials. It exposes an SSH interface on port 22/TCP. This interface is used for remote maintenance and for SFTP file-transfer operations that are part of engineering software functionality. Access to this interface is controlled by 5 preconfigured accounts (root, abuilder, acelogin, cappl, ace), all of which come with default credentials. Although the ACE1000 documentation mentions the root, abuilder and acelogin accounts and instructs users to change the default credentials, the cappl and ace accounts remain undocumented and thus are unlikely to have their credentials changed.

Motorola ACE1000 RTUs through 2022-05-02 mishandle application integrity. They allow for custom application installation via either STS software, the C toolkit, or the ACE1000 Easy Configurator. In the case of the Easy Configurator, application images (as PLX/DAT/APP/CRC files) are uploaded via the Web UI. In case of the C toolkit, they are transferred and installed using SFTP/SSH. In each case, application images were found to have no authentication (in the form of firmware signing) and only relied on insecure checksums for regular integrity checks.

The Motorola MOSCAD Toolbox software through 2022-05-02 relies on a cleartext password. It utilizes an MDLC driver to communicate with MOSCAD/ACE RTUs for engineering purposes. Access to these communications is protected by a password stored in cleartext in the wmdlcdrv.ini driver configuration file. In addition, this password is used for access control to MOSCAD/STS projects protected with the Legacy Password feature. In this case, an insecure CRC of the password is present in the project file: this CRC is validated against the password in the driver configuration file.

The Motorola MDLC protocol through 2022-05-02 mishandles message integrity. It supports three security modes: Plain, Legacy Encryption, and New Encryption. In Legacy Encryption mode, traffic is encrypted via the Tiny Encryption Algorithm (TEA) block-cipher in ECB mode. This mode of operation does not offer message integrity and offers reduced confidentiality above the block level, as demonstrated by an ECB Penguin attack against any block ciphers.
