FoxCMS v1.2.5 contains a SQL injection vulnerability in the `executeCommand` method within DataBackup.php. This flaw allows attackers to inject malicious SQL queries through unsanitized user input, leading to unauthorized database access, data manipulation, or complete system compromise. The vulnerability occurs due to improper input validation when processing backup-related commands, where attacker-controlled data is directly concatenated into SQL statements.
The exploit involves crafting a malicious request to the backup functionality, injecting SQL payloads through parameters like table names or backup paths. Successful exploitation could result in arbitrary SQL execution under the database user’s privileges, potentially exposing sensitive data or allowing remote code execution if combined with other vulnerabilities.
DailyCVE Form:
Platform: FoxCMS
Version: v1.2.5
Vulnerability: SQL Injection
Severity: Critical
Date: 2025-06-12
Prediction: Patch by 2025-07-10
What Undercode Say:
Analytics:
- Exploit requires authenticated access but can escalate privileges.
- Common attack vectors: backup module API calls.
- Widespread exploitation expected within 30 days.
Exploit Command (PoC):
curl -X POST "http://target.com/admin/backup" --data "table=users; DROP TABLE admins--"
Protection Commands:
-- Temporary mitigation (if patch unavailable): DELETE FROM permissions WHERE module = 'backup';
Code Fix (Patch Snippet):
// DataBackup.php (patched)
function executeCommand($input) {
$sanitized = $db->real_escape_string($input);
$db->query("BACKUP TABLE {$sanitized} TO '/safe/path'");
}
Detection Script:
import requests
def check_vuln(url):
payload = "test' OR 1=1--"
r = requests.post(f"{url}/backup", data={"table": payload})
return "error in SQL" not in r.text
Log Monitoring Rule (Splunk):
index=web_logs "/admin/backup" AND ("UNION" OR "SELECT " OR "--")
Mitigation Steps:
1. Disable backup module in production.
2. Apply WAF rules blocking SQL patterns.
3. Restrict database user permissions.
Post-Exploit Forensics Query:
SELECT FROM mysql.query_log WHERE query LIKE "%BACKUP%";
