Description
A vulnerability exists in ChurchCRM 5.13.0 and prior that allows an attacker to execute arbitrary SQL queries by exploiting a time-based blind SQL Injection vulnerability in the EditEventTypes functionality. The newCountName parameter is directly concatenated into an SQL query without proper sanitization, allowing an attacker to manipulate database queries and execute arbitrary commands, potentially leading to data exfiltration, modification, or deletion.

Comprehensive Technical Analysis of EUVD-2025-4527
1. Vulnerability Assessment and Severity Evaluation
The vulnerability described in EUVD-2025-4527 pertains to a time-based blind SQL Injection in the EditEventTypes functionality of ChurchCRM 5.13.0 and prior versions. The newCountName parameter is directly concatenated into an SQL query without proper sanitization, allowing an attacker to manipulate database queries and execute arbitrary commands.
Severity Evaluation:
- Base Score: 9.3 (Critical)
- Base Score Version: 4.0
- Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:L/SA:H/AU:Y/R:U/V:C/RE:H/U:Red
The high base score indicates a critical vulnerability due to the potential for significant data exfiltration, modification, or deletion. The attack vector is network-based (AV:N), requires low complexity (AC:L), and does not require user interaction (UI:N). The impact on confidentiality, integrity, and availability is high (VC:H, VI:H, VA:H), and the scope change is also high (SC:H).
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Network-Based Attack: The attacker can exploit the vulnerability remotely over the network.
- Time-Based Blind SQL Injection: The attacker can inject malicious SQL code that causes a delay in the database response, allowing them to infer information about the database structure and contents.
Exploitation Methods:
- SQL Injection: The attacker can craft SQL queries that include time-based delays to extract information. For example, using
SLEEP()functions to determine the existence of specific data. - Data Exfiltration: By manipulating SQL queries, the attacker can extract sensitive information such as user credentials, personal data, and other confidential information.
- Data Modification: The attacker can alter database entries, leading to integrity issues.
- Data Deletion: The attacker can delete critical data, causing availability issues.
3. Affected Systems and Software Versions
Affected Systems:
- ChurchCRM versions 5.13.0 and prior.
Software Versions:
- All versions up to and including 5.13.0 are vulnerable.
4. Recommended Mitigation Strategies
Immediate Mitigation:
- Patching: Upgrade to a patched version of ChurchCRM that addresses this vulnerability.
- Input Sanitization: Ensure all user inputs are properly sanitized and validated before being used in SQL queries.
- Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
- Web Application Firewall (WAF): Deploy a WAF to detect and block SQL injection attempts.
Long-Term Mitigation:
- Regular Security Audits: Conduct regular security audits and code reviews to identify and fix vulnerabilities.
- Security Training: Provide training for developers on secure coding practices.
- Monitoring and Logging: Implement robust monitoring and logging to detect and respond to suspicious activities.
5. Impact on European Cybersecurity Landscape
The vulnerability in ChurchCRM poses a significant risk to organizations using this software, particularly those handling sensitive data. Given the critical nature of the vulnerability, it could lead to data breaches, financial loss, and reputational damage. The European cybersecurity landscape must prioritize addressing such vulnerabilities to protect personal data and comply with regulations such as GDPR.
