CVE-2024-1011 is a medium severity improper access control flaw, scored 4.3, in SourceCodester Employee Management System 1.0. The public record names no fixed version. Restrict network access to the product, check your installed version against the one named in the record, and watch the vendor or project page for a patch.
What's affected
Affected: SourceCodester Employee Management System 1.0. The record's CVSS 3.1 score is 4.3 (medium), with vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N. The record names delete-leave.php in the leave handler and its id argument. The weakness is filed as CWE-284.
Fixed version: The record names no fixed version. No patched release is confirmed, so check the vendor or project page.
The record's kev flag is false, so this CVE is not in the CISA Known Exploited Vulnerabilities catalog.
How to check if you're exposed
- Find the product in your inventory and confirm the version. Many of these small applications are installed from a source archive, so the version may live in a file or a database table and not in a package manager.
- Check which networks can reach the application, and whether it is exposed to the internet.
- Review application logs for delete or change requests on records that belong to other users. Test with two ordinary accounts to confirm one cannot act on the other's records.
- Check the vendor or project page for a release newer than the affected one.
What to do now
- Take the product off the internet if it is exposed. Put it behind a VPN or an allow list of known addresses.
- Restrict access at the network layer to the people and systems that need it.
- Watch the vendor or project page for a fixed release, and apply it when one appears. The record does not confirm any patch, so check the source directly.
- Review logs for the signs above and rotate administrator credentials if you see anything unusual.
- Add the product to your inventory and monitoring so a future fix or advisory reaches you. A free in-browser dependency scan covers the third party packages in software you build, though it does not inspect device firmware.
Why it matters
Improper access control means the application performs an action without checking that the current user is allowed to do it. Here the record points at a leave handler that acts on an id parameter, so a user can affect records they should not control just by supplying a different id.
The score is low because the vector needs a login and shows only limited integrity impact. In an HR system, though, tampering with leave records is a trust and audit problem even when no data leaves the system.
Smaller commercial and sample code projects often have no security contact and no release cadence. If no fix arrives, the choices are to harden around the product or to replace it.
The record states that the exploit has been disclosed to the public. That means details are available to others, not that attacks have been observed. Only CISA KEV or a vendor advisory can say that, and neither does here.
Quick check
Is this CVE exploited in the wild?
The record's kev flag is false, so it is not in the CISA Known Exploited Vulnerabilities catalog, and no source I read reports active exploitation. The record does say a public exploit exists. That is a reason to patch or contain it soon, not a report of attacks.
What if there is no patch?
Reduce exposure. Remove internet access, restrict the network, apply the log and credential checks above, and plan to replace the product if it holds sensitive data.
