Health Sciences InForm: Improper Access Control
CVE-2023-21923 is a high-severity improper access control vulnerability in Health Sciences InForm from Oracle, with a CVSS 3.1 base score of 8.3 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions 6.3.1.3, 7.0.0.1 as the first without the flaw, so updating Health Sciences InForm to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.59% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Health Sciences InForm to 6.3.1.3 or 7.0.0.1, whichever matches your release line, or a later version.
- Read the advisory on oracle.com for workarounds and exact fixed builds.

Official description
Vulnerability in the Oracle Health Sciences InForm product of Oracle Health Sciences Applications (component: Core). Supported versions that are affected are Prior to 6.3.1.3 and Prior to 7.0.0.1. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Health Sciences InForm. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Health Sciences InForm accessible data as well as unauthorized access to critical data or complete access to all Oracle Health Sciences InForm accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Health Sciences InForm. CVSS 3.1 Base Score 8.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L).

The underlying weakness: Improper Access Control
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
