What is CVE-2026-28760?
CVE-2026-28760 is a security flaw in RATOC RAID Monitoring Manager for Windows. The installer of RATOC RAID Monitoring Manager for Windows searches the current directory to load certain DLLs. If a user is directed to place a crafted DLL with the installer, an arbitrary code may be executed with the administrator privilege.
Why this CVE matters
Unpatched network-facing software is the leading initial-access vector in public breach reporting. Treat any CVSS-9 class flaw on an internet-reachable system as urgent, regardless of whether public exploit code has been observed yet.
For deployments of RATOC RAID Monitoring Manager for Windows that have been exposed to the public internet during the disclosure window, the operating assumption should be that scanning has already happened. Even where exploitation has not been publicly observed, scanning for the vulnerable fingerprint is cheap and routine. Patching closes the door; log review and credential rotation close out the rest of the response.
Am I affected?
You are affected if your installation matches any of these version ranges:
- RATOC RAID Monitoring Manager for Windows: prior to 2.00.009.260220
Check your installed version against the list above. If you cannot determine the version, treat the system as affected and follow the upgrade path below.
Open RATOC RAID Monitoring Manager for Windows's About dialog or run the vendor-documented version-check command. Compare the result against the affected ranges in the advisory.
How to fix CVE-2026-28760
- Read the vendor advisory in full: https://www.ratocsystems.com/topics/userinfo/raidmanager202508/
- Upgrade RATOC RAID Monitoring Manager for Windows to the patched build listed in the vendor advisory.
- Back up the configuration (and database, where applicable) before upgrading.
- Apply the patch in a maintenance window. For HA pairs, upgrade the standby node first, fail over, then upgrade the former primary.
- Restart the affected service so the patched binary loads, then verify the new version (see verification section).
The commands below are runnable starting points. Adapt the package name, target version, and host paths to your environment using the vendor advisory linked under References.

If you cannot patch immediately
No official workaround exists beyond restricting network exposure to the affected component. Apply the vendor patch as the primary remediation.
How to verify the fix worked
- After applying the patch, verify the running version in the product's admin UI or via the vendor-documented CLI command.
- Confirm the patched build matches the version listed in the vendor advisory.
- Run an authenticated vulnerability scan with a current signature set and confirm the scanner no longer flags CVE-2026-28760.
- Review logs for the entire pre-patch window for indicators of compromise listed in the vendor or CISA advisory.
- Confirm any network-layer mitigations that were applied as a stopgap have been reverted (or left in place intentionally) once the patch is verified.
If your installation was internet-reachable during the disclosure window, treat log review as part of the remediation rather than an optional follow-up. Look for log entries that do not match your normal request patterns, especially repeated requests to the same uncommon endpoint, and any administrative changes you cannot tie back to a known operator.
Frequently asked questions
Is CVE-2026-28760 being exploited in the wild?
Public exploitation has not been confirmed by CISA at the time of writing. Treat the patch as time-sensitive anyway; reports often lag actual abuse.
Will a WAF or IDS rule fully mitigate CVE-2026-28760?
No. Network-layer filters can reduce noise and slow opportunistic scanners, but they will not stop a determined attacker. The vendor patch is the only durable fix.
How long should I plan for the upgrade?
Typical vendor-documented upgrade windows for RATOC RAID Monitoring Manager for Windows run from a few minutes to under an hour depending on cluster size. Test in a staging environment first and follow the vendor's documented HA upgrade order.
