CRITICAL 9.8

DescriptionNVD

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.

AnalysisAI

The Motorola ACE1000 RTU through 2022-05-02 uses ECB encryption unsafely. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

Technical ContextAI

This vulnerability is classified as Use of Hard-coded Credentials (CWE-798), which allows attackers to gain access using credentials embedded in source code. 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. Affected products include: Motorola Ace1000 Firmware. Version information: through 2022.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Remove hard-coded credentials, use environment variables or secrets management, rotate exposed credentials immediately.
