CVE-2023-2564

Comprehensive Technical Analysis of CVE-2023-2564

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2023-2564 Description: OS Command Injection in GitHub repository sbs20/scanservjs prior to v2.27.0. CVSS Score: 10

The CVSS score of 10 indicates that this vulnerability is critical. OS Command Injection vulnerabilities allow attackers to execute arbitrary commands on the host operating system, potentially leading to full system compromise. This type of vulnerability is particularly dangerous because it can result in unauthorized access, data breaches, and system takeovers.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Untrusted Input: An attacker can exploit this vulnerability by injecting malicious commands through untrusted input fields.
• Web Interface: If the application has a web interface, attackers can inject commands through HTTP requests.
• API Endpoints: If the application exposes API endpoints, attackers can send crafted requests to execute arbitrary commands.

Exploitation Methods:

• Command Injection: Attackers can inject commands by manipulating input parameters to include OS commands.
• Script Injection: Attackers can inject scripts that execute commands on the underlying OS.
• Chaining Exploits: Attackers can chain this vulnerability with other exploits to escalate privileges or move laterally within the network.

3. Affected Systems and Software Versions

Affected Software:
