CVE-2018-6827 : Vulnerability Insights and Analysis

Devices with VOBOT CLOCK versions prior to 0.99.30 are vulnerable to man-in-the-middle attacks due to a lack of X.509 certificate verification, potentially leading to sensitive data exposure and arbitrary code execution.

Understanding CVE-2018-6827

Devices with VOBOT CLOCK versions before 0.99.30 are susceptible to exploitation through a specific --no-check-certificate option in Wget, allowing attackers to deceive the device into communicating with spoofed servers.

What is CVE-2018-6827?

VOBOT CLOCK devices running versions earlier than 0.99.30 fail to verify X.509 certificates from SSL servers, creating a security gap that can be exploited by attackers to intercept communications and execute malicious code.

The Impact of CVE-2018-6827

Vulnerability exposes devices to man-in-the-middle attacks
Attackers can deceive devices into communicating with spoofed servers
Sensitive information can be accessed, and arbitrary code execution is possible
