Time Clock Plugin Vulnerable to Remote Code Execution

CVE-2024-9593

What is CVE-2024-9593?

CVE-2024-9593 is a critical vulnerability found in the Time Clock and Time Clock Pro plugins for WordPress, versions up to and including 1.2.2 and 1.1.4 respectively. These plugins are designed to provide time tracking and management functions for WordPress sites. The vulnerability allows unauthenticated attackers to execute remote code on servers running these plugins, which poses a severe risk to the integrity and security of the affected WordPress installations. Organizations leveraging these plugins may be exposed to unauthorized access, data manipulation, and potential system compromise due to this flaw.

Technical Details

The vulnerability stems from the etimeclockwp_load_function_callback function, which lacks proper validation on its parameters. This oversight permits attackers to craft malicious requests that can lead to remote code execution without needing authentication. As a result, any individual with knowledge of this vulnerability can potentially manipulate the server environment and execute arbitrary code, making it critical for administrators to address this issue swiftly.

Potential Impact of CVE-2024-9593

1. Unauthorized Server Access: The most immediate impact is the ability for attackers to gain unauthorized control over the server hosting the vulnerable plugins, which can be leveraged to execute arbitrary commands.

2. Data Breaches: With remote code execution capabilities, attackers can access, modify, or exfiltrate sensitive data stored on the web server, leading to potential data breaches and loss of confidential information.

3. Malware Deployment: Compromised servers can be used to deploy malware, ransomware, or additional exploits, further jeopardizing organizational security and potentially affecting customer trust and business operations.
