Security readout for executives and security teams
Plain-English summary
CVE-2020-36920 affects Yerootech iDS6 DSSPro Digital Signage System 6.2. A logged-in user can abuse weak access controls to increase privileges, change roles, create users, and potentially take over the application. Public exploit references exist, but the provided sources do not show confirmed active exploitation.
Executive priority
Prioritize remediation if DSSPro 6.2 is in use. The business risk is unauthorized control of digital signage administration, including account and permission changes. Treat internet-exposed or broadly accessible deployments as urgent.
Technical view
The flaw is improper access control, mapped to CWE-863, in iDS6 DSSPro 6.2. Sources describe privilege escalation through console JavaScript functions and insecure direct object references. CVSS 3.1 is 8.8, with network access, low complexity, low privileges required, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to organizations running iDS6 DSSPro Digital Signage System 6.2, especially if the management interface is reachable by broad internal users or the internet. Exploitation requires valid authentication, but low-privileged accounts may be enough.
Exploitation context
Exploit writeups are listed by Exploit-DB, Packet Storm, CXSecurity, and other advisories. CISA KEV status is not indicated, and the provided sources do not confirm in-the-wild exploitation. Public technical detail increases risk for any still-deployed instance.
Researcher notes
Sources identify version 6.2 only. No vendor patch or fixed version is provided in the bundle. Avoid assuming broader Yerootech product impact. Public exploit references exist, but active exploitation is not established by the provided evidence.
Mitigation direction
- Identify whether iDS6 DSSPro Digital Signage System 6.2 is deployed.
- Check Yerootech or trusted advisory sources for official upgrade or mitigation guidance.
- Restrict DSSPro administrative access to trusted management networks only.
- Review and minimize user accounts, roles, and permissions.
- Disable or decommission exposed DSSPro instances if no supported fix is available.
- Monitor for unexpected user creation, role changes, or permission modifications.
Validation and detection
- Confirm product name and version from asset inventory or application administration screens.
- Review whether the DSSPro interface is reachable from untrusted networks.
- Audit application users for low-privileged accounts with unexpected administrative permissions.
- Check logs for unauthorized role, permission, or user management changes.
- Verify compensating controls restrict access to only approved administrators.

Incorrect Authorization
Incorrect Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
