CVE-2021-44793: Information Leakege via Unauthorized Access in Single Connect

Single Connect does not perform an authorization check when using the sc-reports-ui" module. A remote attacker could exploit this vulnerability to access the device configuration page and export the data to an external file. The exploitation of this vulnerability might allow a remote attacker to obtain sensitive information including the database credentials. Since the database runs with high privileges it is possible to execute commands with the attained credentials.

Security readout for executives and security teams

Plain-English summary

This flaw lets an unauthenticated remote attacker reach a Single Connect configuration/reporting area and export sensitive data. The source description specifically calls out database credentials, with potential command execution if those privileged credentials are abused. Business urgency is high where Single Connect is reachable from untrusted networks.

Executive priority

Prioritize review within the next remediation cycle, faster for internet-facing systems. The main business risk is credential exposure that could enable deeper compromise. Lack of version and fix detail means teams should confirm vendor guidance before declaring systems safe.

Technical view

CVE-2021-44793 is a missing authorization check in Kron Single Connect’s sc-reports-ui module. CVSS 3.1 is 8.6, network exploitable, low complexity, no privileges, no user interaction. The issue is mapped to CWE-862 and may expose configuration data, including database credentials.

Likely exposure

Exposure is most likely in organizations running Kron Single Connect with the sc-reports-ui module reachable over the network. The source bundle does not identify affected version ranges, fixed versions, or specific deployment defaults, so asset discovery and vendor confirmation are required.

Exploitation context

The CVE record describes remote unauthenticated exploitation potential, but the bundle does not provide exploit code, observed exploitation, or KEV listing. Treat internet-facing or broadly reachable deployments as urgent because leaked privileged database credentials can expand impact beyond information disclosure.

Researcher notes

Evidence is limited to the CVE description, CVSS vector, CWE, and advisory URLs. The affected version field is unspecified, and no patch, workaround, exploit status, or incident evidence is included in the provided bundle.

Mitigation direction

  • Check Kron and listed government advisories for fixed versions or supported workarounds.
  • Restrict Single Connect and reporting interfaces to trusted administrative networks.
  • Require VPN or equivalent access controls for management and reporting paths.
  • Rotate database credentials if exposure or unauthorized export is suspected.
  • Reduce database privilege where operationally possible after vendor review.

Validation and detection

  • Inventory Kron Single Connect deployments and identify sc-reports-ui exposure.
  • Confirm product version and fix status with vendor or government advisory details.
  • Test from untrusted networks that configuration and reporting pages are inaccessible.
  • Review logs for unexpected configuration page access or export activity.
  • Check whether database credentials are privileged, reused, or stored in exported data.

Missing Authorization

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