EUVD-2024-44340

Comprehensive Technical Analysis of EUVD-2024-44340

1. Vulnerability Assessment and Severity Evaluation

The vulnerability in the LifterLMS – WordPress LMS Plugin for eLearning, identified as EUVD-2024-44340, is an SQL Injection vulnerability. This issue arises due to insufficient escaping of user-supplied parameters and inadequate preparation of SQL queries, specifically affecting the orderBy attribute of the lifterlms_favorites shortcode. The vulnerability allows authenticated attackers with Contributor-level access or higher to inject malicious SQL queries, potentially extracting sensitive information from the database.

Severity Evaluation:

• CVSS Base Score: 9.8
• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The high CVSS score indicates a critical vulnerability due to the ease of exploitation (low complexity), the lack of user interaction required, and the significant impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Authenticated SQL Injection: An attacker with Contributor-level access or higher can manipulate the orderBy parameter in the lifterlms_favorites shortcode to inject SQL commands.
2. Data Exfiltration: By injecting SQL queries, attackers can extract sensitive data such as user credentials, personal information, and other confidential data stored in the database.
3. Database Manipulation: Attackers can alter, delete, or insert data into the database, compromising the integrity and availability of the application.

Exploitation Methods:

• Manual Exploitation: Attackers can manually craft SQL injection payloads and test them against the vulnerable parameter.
• Automated Tools: Use of automated SQL injection tools to identify and exploit the vulnerability.

3. Affected Systems and Software Versions

Affected Software:

• LifterLMS – WordPress LMS Plugin for eLearning
• Versions: All versions up to and including 7.6.2
