CVE-2023-36610 : What You Need to Know

A detailed analysis of CVE-2023-36610 focusing on the vulnerability, impact, technical details, and mitigation steps.

Understanding CVE-2023-36610

This section delves into the specifics of CVE-2023-36610, shedding light on the nature of the vulnerability, its impact, and ways to safeguard against it.

What is CVE-2023-36610?

The affected TBox RTUs generate software security tokens using insufficient entropy. This inadequacy in token generation leaves the system susceptible to brute force attacks, where an attacker could authenticate themselves exploiting predictable time-based values.

The Impact of CVE-2023-36610

The CVSSv3.1 base score rates this vulnerability as 5.9, categorizing it as having a medium severity level with high confidentiality impact. The attack complexity is considered high with a network-based attack vector.

Technical Details of CVE-2023-36610

Here we delve into the specifics of the vulnerability, the affected systems and versions, as well as the exploitation mechanism.

Vulnerability Description

The flawed token generation process in TBox RTUs due to insufficient entropy allows attackers to brute force authentication tokens, posing a significant security risk.

Affected Systems and Versions

Ovarro's TBox MS-CPU32, TBox MS-CPU32-S2, TBox LT2, TBox TG2, and TBox RM2 versions up to 1.50.598 are affected by this vulnerability.

Exploitation Mechanism

Due to the predictable nature of token generation in TBox RTUs, attackers can exploit this vulnerability by brute forcing the security tokens to gain unauthorized access.
