RAONWIZ v2018.0.2.50 and earlier versions contains a vulnerability that could allow remote files to be downloaded by lack of validation. Vulnerabilities in downloading with Kupload agent allow files to be downloaded to arbitrary paths due to insufficient verification of extensions and download paths. This issue affects: RAONWIZ RAON KUpload 2018.0.2.50 versions and earlier.

Security readout for executives and security teams

Plain-English summary

RAON KUpload versions 2018.0.2.50 and earlier can download files to unintended locations because download paths and extensions are not sufficiently validated. A successful attack could affect confidentiality, integrity, and availability. Exposure depends on whether the vulnerable KUpload agent is deployed and used in business workflows.

Executive priority

Treat as high priority where RAON KUpload is deployed, especially on user endpoints supporting file-transfer workflows. Prioritize inventory first because business impact depends on whether this legacy component is present.

Technical view

CVE-2020-7830 affects RAONWIZ RAON KUpload <=2018.0.2.50. The issue is insufficient verification of file extensions and download paths in the Kupload agent, allowing downloads to arbitrary paths. CVSS 3.1 is 7.8 with local attack vector, no privileges required, and user interaction required.

Likely exposure

Organizations with RAON KUpload agent version 2018.0.2.50 or earlier are potentially exposed. The bundle does not establish broad internet-facing exposure; CVSS indicates local attack vector with required user interaction.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation evidence. The CVSS vector indicates exploitation requires user interaction and no privileges. Do not assume weaponized public exploitation from these sources alone.

Researcher notes

Evidence is limited to the CVE description, CVSS vector, affected version range, and KRCERT reference. No CWE, fixed version, exploit details, or active exploitation status are provided in the bundle.

Mitigation direction

  • Identify RAON KUpload installations and versions across endpoints and application workflows.
  • Upgrade or remediate according to RAONWIZ and KRCERT guidance.
  • Retire legacy KUpload agent deployments no longer required by business processes.
  • Restrict vulnerable download workflows to trusted users and trusted content only.
  • Monitor for unexpected file creation by the KUpload agent.

Validation and detection

  • Confirm whether RAON KUpload is deployed in the environment.
  • Compare deployed versions against 2018.0.2.50 and earlier.
  • Review KUpload download workflows for path and extension validation exposure.
  • Check endpoint telemetry for unusual files written by the KUpload agent.
  • Verify vendor or KRCERT guidance before closing remediation.
