Security readout for executives and security teams
Plain-English summary
This flaw lets a logged-in, unauthorized user change other users' privileges in Star Practice Management Web 2019.2.0.6. The business risk is account takeover at the application level, including creating an administrator or removing all administrators, which could disrupt operations and expose sensitive records.
Executive priority
Treat as high priority where the affected product is deployed. The main concern is internal misuse or compromised low-privileged accounts becoming administrators, which can quickly affect confidentiality, integrity, and continuity.
Technical view
CVE-2020-28405 is an improper authorization issue in Star Practice Management Web 2019.2.0.6. The CVSS 3.1 score is 8.8, with network attack vector, low complexity, low privileges required, no user interaction, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure appears limited to deployments of Star Practice Management Web 2019.2.0.6. The source bundle lists affected vendor/product metadata as n/a, so asset owners should confirm product naming and deployed versions internally.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The vulnerability is serious because any low-privileged authenticated user may be able to elevate privileges or remove administrator access.
Researcher notes
Evidence is limited to the CVE description and referenced advisories. Affected metadata in the bundle is incomplete, and no specific patch version is provided. Avoid assuming exploitation in the wild without additional cited evidence.
Mitigation direction
- Identify any Star Practice Management Web 2019.2.0.6 deployments.
- Check Star Practice Management, Excellium, and Thales advisory guidance for fixes.
- Restrict access to the application to trusted networks and users.
- Review all current administrator accounts for unauthorized changes.
- Back up configuration and account data before remediation work.
Validation and detection
- Confirm deployed application name and version against 2019.2.0.6.
- Review audit logs for role or privilege changes by non-administrators.
- Verify low-privileged accounts cannot access role-management functions in staging.
- Check whether any administrator accounts were removed unexpectedly.
- Document compensating controls if a vendor fix is unavailable.
