Security readout for executives and security teams
Plain-English summary
RemotePC for Windows before 7.6.48 could expose a system Personal Key to any user already logged into the machine. The key was stored in readable log files in encrypted form, but the encryption used a static hard-coded key, making recovery possible.
Executive priority
Prioritize remediation on shared workstations, servers, and support machines where local account compromise would create remote access risk. This is not currently evidenced as internet-exploited, but exposed remote access secrets deserve timely cleanup.
Technical view
A locally authenticated attacker could read world-readable %PROGRAMDATA% log files containing the encrypted RemotePC Personal Key. Because the encryption used a hard-coded static key, the protected value was reversible. Sources identify affected Windows versions as RemotePC before 7.6.48.
Likely exposure
Exposure is limited to Windows systems running iDrive RemotePC before 7.6.48 where local users or compromised local accounts can read the relevant ProgramData logs.
Exploitation context
The source bundle does not show CISA KEV listing or confirmed active exploitation. Exploitation requires local authenticated access, but disclosure of the Personal Key could materially affect remote access security.
Researcher notes
The public record names the vulnerable condition and version boundary, but CVSS, CWE, and structured CPE data are absent. Treat product identification carefully and validate against installed RemotePC Windows versions rather than relying on CPE matching.
Mitigation direction
- Upgrade RemotePC for Windows to 7.6.48 or later per vendor release information.
- Restrict local account access on systems running RemotePC.
- Review vendor guidance for any additional cleanup or key-rotation recommendations.
- Rotate affected RemotePC Personal Keys where exposure is suspected.
Validation and detection
- Inventory Windows endpoints running RemotePC and record installed versions.
- Flag any RemotePC versions earlier than 7.6.48.
- Review ProgramData RemotePC logs for exposed Personal Key artifacts.
- Confirm local log file permissions are no longer broadly readable after remediation.
