Description
A vulnerability exists in ChurchCRM 5.13.0 and prior that allows an attacker to execute arbitrary SQL queries by exploiting a boolean-based and time-based blind SQL Injection vulnerability in the DonatedItemEditor functionality. The CurrentFundraiser parameter is directly concatenated into an SQL query without sufficient sanitization, allowing an attacker to manipulate database queries and execute arbitrary commands, potentially leading to data exfiltration, modification, or deletion. Please note that this vulnerability requires Administrator privileges.

Comprehensive Technical Analysis of EUVD-2025-4717
1. Vulnerability Assessment and Severity Evaluation
The vulnerability EUVD-2025-4717 affects ChurchCRM versions 5.13.0 and prior. It is classified as a boolean-based and time-based blind SQL Injection vulnerability in the DonatedItemEditor functionality. The CurrentFundraiser parameter is directly concatenated into an SQL query without sufficient sanitization, allowing an attacker to manipulate database queries and execute arbitrary commands.
Severity Evaluation:
- Base Score: 9.3 (CVSS 4.0)
- Vector String: 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. Key factors contributing to the severity include:
- Attack Vector (AV:N): Network-based attack, meaning it can be exploited remotely.
- Attack Complexity (AC:L): Low complexity, indicating that the attack does not require specialized conditions.
- Privileges Required (PR:H): High privileges are required, meaning the attacker needs Administrator privileges.
- User Interaction (UI:N): No user interaction is required.
- Confidentiality, Integrity, and Availability Impact (VC:H, VI:H, VA:H): High impact on all three aspects, indicating potential data exfiltration, modification, or deletion.
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Remote Exploitation: An attacker can exploit this vulnerability over the network without needing physical access to the system.
- Administrator Privileges: The attacker must have Administrator privileges to exploit this vulnerability.
Exploitation Methods:
- Boolean-Based Blind SQL Injection: The attacker can inject SQL code that returns different results based on whether a condition is true or false.
- Time-Based Blind SQL Injection: The attacker can inject SQL code that causes a delay in the response, allowing them to infer information based on the time it takes for the query to execute.
Example Exploit:
An attacker could inject SQL code into the CurrentFundraiser parameter to manipulate the database query. For example:
CurrentFundraiser=1 OR 1=1; --
This would cause the SQL query to always return true, potentially bypassing authentication or authorization checks.
3. Affected Systems and Software Versions
Affected Software:
- ChurchCRM versions 5.13.0 and prior.
Systems:
- Any system running the affected versions of ChurchCRM, particularly those with network access and Administrator privileges.
4. Recommended Mitigation Strategies
Immediate Mitigation:
- Patching: Upgrade to a version of ChurchCRM that addresses this vulnerability.
- Input Sanitization: Ensure that 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.
- Least Privilege: Implement the principle of least privilege to limit the impact of potential exploits.
Long-Term Mitigation:
- Regular Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.
- Security Training: Provide training for developers and administrators on secure coding practices and SQL injection prevention.
- Monitoring: Implement monitoring and alerting systems to detect and respond to suspicious activities.
5. Impact on European Cybersecurity Landscape
The vulnerability poses a significant risk to organizations using ChurchCRM, particularly those in the European Union. Given the high base score and the potential for data exfiltration, modification, or deletion, this vulnerability could lead to:
- Data Breaches: Unauthorized access to sensitive information.
- Compliance Issues: Violation of data protection regulations such as GDPR.
- Operational Disruptions: Potential downtime or loss of service due to data corruption or deletion.
6. Technical Details for Security Professionals
Vulnerability Details:
- CWE ID: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'))
- Exploitability: The vulnerability can be exploited by injecting malicious SQL code into the
CurrentFundraiserparameter. - Detection: Monitor for unusual database query patterns, such as unexpected delays or boolean-based responses.
Mitigation Steps:
- Upgrade Software: Ensure all instances of ChurchCRM are upgraded to a version that addresses this vulnerability.
- Implement Input Validation: Use input validation libraries and frameworks to sanitize user inputs.
- Use Parameterized Queries: Replace direct SQL query concatenation with parameterized queries.
- Regular Patching: Establish a regular patching schedule to ensure all software is up-to-date.
- Intrusion Detection: Deploy intrusion detection systems (IDS) to monitor for suspicious activities.
