Security readout for executives and security teams
Plain-English summary
Kron Single Connect has a missing authorization check in the sc-assigned-credential-ui module. A remote unauthenticated attacker may be able to change or remove another user's permissions, creating access-control and operational disruption risk. Public sources rate it medium severity, and it is not KEV-listed.
Executive priority
Treat this as a moderate-priority identity and access-control risk. It does not have confirmed active exploitation in the provided sources, but unauthenticated permission changes can affect business access and governance. Prioritize confirming whether Single Connect exists in the environment and whether vendor guidance is available.
Technical view
CVE-2021-44795 is CWE-862 missing authorization. The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N with score 5.3. The public description says unauthorized remote access to the sc-assigned-credential-ui module can modify user permissions, including deleting permissions without authentication.
Likely exposure
Exposure is likely limited to organizations running Kron Single Connect, especially deployments where the affected module is reachable over a network. The source bundle does not identify specific affected versions, CPEs, deployment defaults, or fixed versions, so asset inventory and vendor confirmation are required.
Exploitation context
The provided sources do not show active exploitation, and the CVE is not listed in KEV. The vulnerability is still operationally relevant because the described access requires no authentication, low attack complexity, and no user interaction, but public evidence is incomplete on real-world abuse.
Researcher notes
The public record is thin: affected versions are unspecified, default status is listed as unaffected, one government reference is marked broken, and no patch details are included. Do not infer broader Kron product exposure or exploit availability from this bundle alone.
Mitigation direction
- Check Kron or official advisory guidance for fixed versions or supported mitigations.
- Restrict network access to Single Connect management and credential-assignment interfaces.
- Review user permissions for unexplained removals or unauthorized changes.
- Increase monitoring around Single Connect permission-management activity.
- If no vendor fix is available, isolate the affected module from untrusted networks.
Validation and detection
- Inventory all Kron Single Connect instances and confirm exposed interfaces.
- Determine whether sc-assigned-credential-ui is present and reachable.
- Ask the vendor to confirm affected and fixed versions for your deployment.
- Review access-control logs for unauthenticated or anomalous permission changes.
- Confirm compensating controls block untrusted access to the affected module.

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