Security readout for executives and security teams
Plain-English summary
CVE-2020-7882 is a high-severity directory traversal issue in Hancomwith anySign4PC. A remote unauthenticated attacker could use unsafe path input to view authorization certificate information, according to the CVE description. The sources do not confirm active exploitation or provide a specific fixed version.
Executive priority
Prioritize remediation for systems where anySign4PC is deployed and reachable. The main business risk is unauthorized exposure of certificate-related information, with sparse public evidence about exploitation or vendor fixes in the provided sources.
Technical view
The flaw affects anySign4PC versions 1.1.1.0, 1.1.2.6, and 1.1.2.7. The getPFXFolderList function accepts path traversal characters in a parameter, mapped to CWE-24. CVSS 3.1 is 7.5: network exploitable, low complexity, no privileges, no user interaction, high confidentiality impact.
Likely exposure
Exposure is limited to environments running the listed Hancomwith anySign4PC versions. Risk is highest where the vulnerable function is reachable over a network and handles certificate-related file paths or authorization certificate storage.
Exploitation context
The provided sources do not show CISA KEV listing, active exploitation, public exploit details, or observed attacks. They only describe the traversal condition and resulting certificate information exposure. Treat exploitation status as unconfirmed.
Researcher notes
The source bundle contains a CVE description, CVSS vector, CWE-24 classification, affected versions, and a KRCERT reference. It does not provide patch details, exploit maturity, or detailed product deployment context. The CVSS vector lists confidentiality impact only, while the description also mentions file deletion.
Mitigation direction
- Inventory anySign4PC installations and versions across endpoints and servers.
- Check Hancomwith or KRCERT guidance for patched versions or vendor workarounds.
- Upgrade or remove affected versions when vendor-approved remediation is available.
- Restrict network reachability to any service exposing vulnerable anySign4PC functionality.
- Review certificate storage permissions and backups for recovery needs.
Validation and detection
- Confirm whether versions 1.1.1.0, 1.1.2.6, or 1.1.2.7 are installed.
- Identify systems where getPFXFolderList-related functionality is network reachable.
- Review logs for suspicious traversal-pattern requests against anySign components.
- Check for unauthorized access to authorization certificate information.
- Verify vendor remediation status after applying any update or workaround.
