**Name of the Vulnerable Software and Affected Versions** T&D Corporation data logger products (TR-71W/72W all firmware versions, RTR-5W all firmware versions, WDR-7 all firmware versions, WDR-3 all firmware versions, and WS-2 all firmware versions) ESPEC MIC CORP. data logger products (RT-12N/RS-12N all firmware versions, RT-22BN all firmware versions, and TEU-12N all firmware versions) **Description** A client-side enforcement of server-side security issue exists in T&D Corporation and ESPEC MIC CORP. data logger products, which may lead to an arbitrary script execution on a logged-in user's web browser. **Recommendations** For T&D Corporation data logger products (TR-71W/72W all firmware versions, RTR-5W all firmware versions, WDR-7 all firmware versions, WDR-3 all firmware versions, and WS-2 all firmware versions), consider disabling the web interface until a patch is available. For ESPEC MIC CORP. data logger products (RT-12N/RS-12N all firmware versions, RT-22BN all firmware versions, and TEU-12N all firmware versions), restrict access to the web interface to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** T&D Corporation data logger products versions TR-71W/72W all firmware versions, RTR-5W all firmware versions, WDR-7 all firmware versions, WDR-3 all firmware versions, and WS-2 all firmware versions ESPEC MIC CORP. data logger products versions RT-12N/RS-12N all firmware versions, RT-22BN all firmware versions, and TEU-12N all firmware versions **Description** Missing authentication for a critical function exists in the affected data logger products, which may allow a remote unauthenticated attacker to alter the product settings without authentication. **Recommendations** For T&D Corporation data logger products, consider disabling remote access to the critical function until a patch is available. For ESPEC MIC CORP. data logger products, restrict access to the product settings to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** T&D Corporation data logger products versions all firmware versions ESPEC MIC CORP. data logger products versions all firmware versions **Description** Cross-site request forgery (CSRF) allows a remote unauthenticated attacker to conduct an arbitrary operation by having a logged-in user view a malicious page. **Recommendations** For T&D Corporation data logger products, consider disabling access to the web interface until a patch is available. For ESPEC MIC CORP. data logger products, restrict access to the web interface to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

For T&D Corporation data logger products versions RTR-5W all firmware versions, restrict access to the product to minimize the risk of exploitation. For T&D Corporation data logger products versions WDR-7 all firmware versions, avoid using default or weak passwords for registered users. For T&D Corporation data logger products versions WDR-3 all firmware versions, limit the number of login attempts to prevent brute-force attacks. For T&D Corporation data logger products versions WS-2 all firmware versions, implement additional authentication mechanisms, such as two-factor authentication. For ESPEC MIC CORP. data logger products versions RT-12N/RS-12N all firmware versions, consider changing default passwords and restricting access to the product. For ESPEC MIC CORP. data logger products versions RT-22BN all firmware versions, disable any unnecessary features or services that could be exploited. For ESPEC MIC CORP. data logger products versions TEU-12N all firmware versions, monitor user activity and login attempts to detect potential exploitation.
