Security readout for executives and security teams
Plain-English summary
This flaw means the affected Taiwan SECOM Dr. ID door access and personnel attendance system includes hard-coded administrative credentials. A remote attacker who can reach the system may gain the highest privileges, creating business risk to access control operations, attendance records, and system availability.
Executive priority
Treat this as urgent for any confirmed deployment, especially if remotely reachable. Administrative compromise of a door access system can affect security operations, data integrity, and availability. Prioritize exposure reduction while seeking vendor-specific remediation.
Technical view
CVE-2021-35961 is a CWE-798 hard-coded credentials issue in TAIWAN SECOM Door Access Control and Personnel Attendance Management system. The CVE states remote attackers can use the default password to access the system with highest permission. CVSS 3.1 is 9.8, with network attack vector and no required authentication or user interaction.
Likely exposure
Exposure is most likely where this specific Taiwan SECOM door access and attendance management system is deployed and reachable from remote networks. The source bundle does not provide affected version ranges, CPEs, or deployment indicators, so asset confirmation is required.
Exploitation context
The sources support remote unauthorized administrative access through hard-coded/default credentials. The bundle does not show CISA KEV listing, public active exploitation, exploit tooling, or confirmed exploitation in the wild.
Researcher notes
Evidence is clear on vulnerability class, privilege impact, and remote attack preconditions. Evidence is incomplete on affected versions, fixed releases, workarounds, exploit status, and indicators of compromise. Avoid assuming other Taiwan SECOM products are affected.
Mitigation direction
- Identify whether the affected Taiwan SECOM system exists in your environment.
- Restrict access to trusted administrative networks only.
- Follow vendor or TWCERT guidance for fixes, upgrades, or configuration changes.
- Disable, rotate, or remove default administrative credentials where supported.
- Review administrative logs for unexpected access or configuration changes.
Validation and detection
- Confirm product identity with asset inventory and system owners.
- Check whether management interfaces are reachable from untrusted networks.
- In an authorized test window, verify default administrative credentials cannot authenticate.
- Review logs for unknown admin sessions, changes, or account creation.
- Track vendor, TWCERT, and Chsecurity advisories for version-specific remediation.

Use of Hard-coded Credentials
Use of Hard-coded Credentials represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
