Vulnerabilities

​All versions of the TWinSoft Configuration Tool store encrypted passwords as plaintext in memory.

The affected TBox RTUs allow low privilege users to access software security tokens of higher privilege.

​The affected TBox RTUs generate software security tokens using insufficient entropy.

The affected TBox RTUs run OpenVPN with root privileges and can run user defined configuration scripts.

The affected TBox RTUs store hashed passwords using MD5 encryption, which is an insecure encryption algorithm.

The affected TBox RTUs are missing authorization for running some API commands.

The “ipk” package containing the configuration created by TWinSoft can be uploaded, extracted, and executed in Ovarro TBox, allowing malicious code execution.

Ovarro TBox TWinSoft uses the custom hardcoded user “TWinSoft” with a hardcoded key.

Ovarro TBox proprietary Modbus file access functions allow attackers to read, alter, or delete the configuration file.

An attacker may use TWinSoft and a malicious source project file (TPG) to extract files on machine executing Ovarro TWinSoft, which could lead to code execution.

An attacker can decrypt the Ovarro TBox login password by communication capture and brute force attacks.

An attacker could use specially crafted invalid Modbus frames to crash the Ovarro TBox system.
