How the CVE Works:
The vulnerability in Pimcore arises from improper input sanitization in the `getRelationFilterCondition` method. This function processes user-supplied filter strings to construct SQL queries. Attackers can exploit this by crafting malicious filter strings containing SQL injection payloads. The unsanitized input is directly concatenated into the SQL query, allowing attackers to manipulate the database. This can lead to unauthorized data access, data modification, or even complete database compromise. The issue is present in the `RelationFilterConditionParser.php` file, where the input is not validated or escaped before being used in the query.
DailyCVE Form:
Platform: Pimcore
Version: Pre-11.0.0
Vulnerability: SQL Injection
Severity: Critical
Date: Mar 11, 2025
What Undercode Say:
Exploitation:
- Crafting Malicious Input: Attackers can send a specially crafted filter string to the `getRelationFilterCondition` method.
Example Payload: `filter=1′ OR ‘1’=’1`
- Exploit via API: If the vulnerable endpoint is exposed via an API, attackers can send HTTP requests with the malicious payload.
Example Command:
curl -X POST -d "filter=1' OR '1'='1" http://target.com/api/endpoint
3. Database Manipulation: Successful exploitation can allow attackers to extract sensitive data, modify records, or execute arbitrary SQL commands.
Protection:
- Input Sanitization: Ensure all user inputs are sanitized and validated before being used in SQL queries.
Example PHP Code:
$filter = mysqli_real_escape_string($connection, $_POST[bash]);
2. Use Prepared Statements: Replace dynamic SQL queries with prepared statements to prevent injection.
Example:
$stmt = $connection->prepare("SELECT FROM table WHERE filter = ?");
$stmt->bind_param("s", $filter);
$stmt->execute();
3. Patch Application: Update Pimcore to the latest version where the vulnerability is fixed.
Command:
composer update pimcore/pimcore
4. Web Application Firewall (WAF): Deploy a WAF to detect and block SQL injection attempts.
Analytics:
- Affected Versions: Pimcore versions before 11.0.0.
- Attack Vector: Remote, authenticated users.
- CVSS Score: 9.8 (Critical).
- Mitigation Complexity: Low (requires code changes and updates).
