EUVD-2024-49242

Comprehensive Technical Analysis of EUVD-2024-49242

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in the LearnPress – WordPress LMS Plugin (EUVD-2024-49242) is an SQL Injection flaw affecting all versions up to and including 4.2.7. This vulnerability arises due to insufficient escaping of the 'c_fields' parameter in the /wp-json/lp/v1/courses/archive-course REST API endpoint and a lack of proper preparation of the SQL query.

Severity Evaluation:

• CVSS Base Score: 10.0
• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

The CVSS score of 10.0 indicates a critical vulnerability. The attack vector (AV:N) is network-based, requiring low complexity (AC:L) and no privileges (PR:N) or user interaction (UI:N). The impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), and the scope is changed (S:C), meaning the vulnerability can affect components beyond the initial security scope.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated SQL Injection: Attackers can exploit this vulnerability without needing authentication, making it highly accessible.
• Data Exfiltration: By injecting malicious SQL queries, attackers can extract sensitive information from the database, such as user credentials, personal data, and other confidential information.
• Database Manipulation: Attackers can alter database entries, delete data, or insert malicious content, compromising the integrity of the database.

Exploitation Methods:

• Manual SQL Injection: Attackers can manually craft SQL injection payloads targeting the 'c_fields' parameter to extract or manipulate data.
• Automated Tools: Use of automated SQL injection tools to scan for and exploit the vulnerability, potentially leading to large-scale data breaches.

3. Affected Systems and Software Versions

Affected Software:

• LearnPress – WordPress LMS Plugin

Affected Versions:

• All versions up to and including 4.2.7

Vendor:
