itsourcecode Apartment Management System 1.0 has a high severity (CVSS 7.3) SQL injection, tracked as CVE-2025-9511. The flaw is in /visitor/addvisitor.php, where the ID argument is used in a query without safe handling. A public exploit is reported and no patched version is named, so restrict the app and fix the query.
What's affected
The record lists itsourcecode Apartment Management System version 1.0. The vulnerable code is /visitor/addvisitor.php, and the affected input is ID. The description says the attack can be carried out remotely and that the exploit has been disclosed publicly.
No fixed version appears in the record, and none of the pages I could reach named one. If the project later publishes a patched release, the maintainer's page is the place to confirm it. Until then, treat every deployed copy of version 1.0 as exposed. The product list in the record uses the label admerc apartment_management_system, while the description names itsourcecode Apartment Management System. These look like the same project, so search for both names when you take inventory.
The weakness is classed as CWE-89 (SQL injection) under the broader CWE-74 (injection) family. The record scores it 7.3 with the vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L: network reachable, low complexity, no privileges and no user interaction, with low impact on confidentiality, integrity and availability.
How to check if you're exposed
Start with inventory. Work out whether you run Apartment Management System at all, and which version. Then look for the file the record names.
find /var/www -type f -name "addvisitor.php"
Adjust the path to wherever your web root lives. A hit on a copy of version 1.0 means the code is present. Next, check reachability: is the application open to the internet, or only to an internal network?
For signs of abuse, read the web server access log for requests to the affected path. Look for odd characters, SQL keywords and unusually long values:
grep -E "addvisitor\.php" /var/log/apache2/access.log | tail -n 100
Access logs show the URL and query string but usually not POST bodies, so also read the PHP and database error logs for query syntax errors and sudden bursts of failures. The free dependency scan at gold.safeguard.sh/scan covers libraries you declare, so it will not see a flaw inside application code you downloaded or wrote yourself. For that, a code scan is the right tool.
What to do now
- Find every deployment of Apartment Management System 1.0, including test and demo copies that were never meant to be public.
- Take the application off the open internet, or put it behind a VPN, an IP allowlist or web server authentication until the code is fixed.
- Replace string built queries in
addvisitor.phpwith prepared statements and bound parameters (mysqli or PDO in PHP), and validate the type ofIDbefore it gets near the database. - Run the application's database account with the least privilege it needs: no administrative rights and no access to other schemas.
- Review access and error logs for the affected path, and rotate database and application credentials if you see signs of abuse.
- Check the project page now and then for a patched release, and retire the application if it is unmaintained.
Why it matters
This is a classic mistake. The query is assembled from text, and the request value goes straight into it. Anyone who can reach the page can try to bend the query, and the public report removes the guesswork about where to look.
An apartment management system typically holds tenant, visitor, billing and staff records, which is the kind of data a database query flaw can expose. The rating of 7.3 reflects that the flaw needs no login and no victim to click anything, offset by limited stated impact per category. The record gives no deployment specific data, so judge your own exposure by what the database holds.
The CVE is not in the CISA Known Exploited Vulnerabilities catalog according to the record. The record does state that a public exploit exists, which is a reason to move quickly on any internet facing copy.
Quick check
Is there a patch for CVE-2025-9511?
The record names no fixed version, and I could not confirm one from the pages I reached. Check the project page, and meanwhile restrict access and fix the query in your own copy.
Do I need to be logged in to exploit CVE-2025-9511?
The vector in the record has no privileges required and no user interaction, so it is treated as reachable by a remote visitor. Confirm against your own deployment, since a login wall you added may change the picture.
Does the Safeguard dependency scan find this?
Not by itself. The scan reads declared packages, and this is a flaw in application source. A code scan or a review of how queries are built is what catches it.
