CVE-2024-2413

Comprehensive Technical Analysis of CVE-2024-2413

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-2413 CVSS Score: 9.8

The vulnerability in Intumit SmartRobot involves the use of a fixed encryption key for authentication, which can be exploited by remote attackers to gain administrator privileges and execute arbitrary code. The CVSS score of 9.8 indicates a critical severity level, reflecting the potential for significant impact on confidentiality, integrity, and availability.

Key Factors Contributing to Severity:

• Authentication Bypass: The use of a fixed encryption key allows attackers to generate valid authentication codes.
• Privilege Escalation: Attackers can obtain administrator privileges, leading to full control over the system.
• Remote Code Execution: The ability to execute arbitrary code on the remote server poses a severe risk to system integrity and data security.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Attackers can exploit the vulnerability over the network, making it accessible from remote locations.
• Phishing and Social Engineering: Attackers may use phishing techniques to trick users into providing necessary information to generate authentication codes.

Exploitation Methods:

• Key Extraction: Attackers can extract the fixed encryption key from the system or intercept it during transmission.
• Authentication Code Generation: Using the extracted key, attackers can encrypt a string composed of the user's name and timestamp to generate a valid authentication code.
• Privilege Escalation: With the authentication code, attackers can gain administrator privileges and execute arbitrary code using built-in system functionality.

3. Affected Systems and Software Versions

Affected Systems:

• Intumit SmartRobot devices running the vulnerable software version.

Software Versions:

• Specific versions of the Intumit SmartRobot software that use the fixed encryption key for authentication.

Note: Detailed information on affected versions should be obtained from Intumit or the referenced sources.
