hospital_management_system: Authorization Bypass Through User-Controlled Key

Published Updated By the CyberSecBulletin desk

CVE-2024-28320 is a high-severity authorization bypass through user-controlled key vulnerability in hospital_management_system from Hospital Management System Project, with a CVSS 3.1 base score of 7.6 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. Affected hospital_management_system versions: 1.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.53% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

Insecure Direct Object References (IDOR) vulnerability in Hospital Management System 1.0 allows attackers to manipulate user parameters for unauthorized access and modifications via crafted POST request to /patient/edit-user.php.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Authorization Bypass Through User-Controlled Key

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.

How developers prevent this class of flaw

  • For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
  • Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
  • Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
