CVE-2021-22648

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

CVE-2021-22646

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

CVE-2021-22640

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

CVE-2021-22650

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.

CVE-2021-22642

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

CVE-2021-22644

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

CVE-2023-36607

The affected TBox RTUs are missing authorization for running some API commands. An attacker running these commands could reveal sensitive information such as software versions and web server file contents.

CVE-2023-36609

The affected TBox RTUs run OpenVPN with root privileges and can run user defined configuration scripts. An attacker could set up a local OpenVPN server and push a malicious script onto the TBox host to acquire root privileges.

CVE-2023-36610

​The affected TBox RTUs generate software security tokens using insufficient entropy. The random seed used to generate the software tokens is not initialized correctly, and other parts of the token are generated using predictable time-based values. An attacker with this knowledge could successfully...

CVE-2023-36611

The affected TBox RTUs allow low privilege users to access software security tokens of higher privilege. This could allow an attacker with “user” privileges to access files requiring higher privileges by establishing an SSH session and providing the other tokens.

CVE-2023-36608

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