Security readout for executives and security teams
Plain-English summary
This flaw affects specific Windows Acronis security and backup products. A DLL hijacking issue could cause denial of service, potentially disrupting protection or recovery operations. The sources do not provide CVSS scoring or evidence of active exploitation.
Executive priority
Handle through normal vulnerability management with business awareness. The direct impact is denial of service, but affected systems may support security, backup, and recovery functions, increasing operational importance.
Technical view
CVE-2021-44199 is a CWE-427 DLL hijacking vulnerability in Acronis Cyber Protect 15, Acronis Agent, and Acronis Cyber Protect Home Office on Windows before specified builds. The documented impact is denial of service; the bundle does not include exploit prerequisites or technical root-cause detail.
Likely exposure
Exposure is limited to Windows systems running Acronis Cyber Protect 15 before build 28035, Acronis Agent before build 27305, or Acronis Cyber Protect Home Office before build 39612.
Exploitation context
The provided bundle does not show CISA KEV listing, public active exploitation, exploit maturity, or CVSS data. Treat exploitation status as unconfirmed, not active.
Researcher notes
The public bundle is sparse: no CVSS vector, exploit prerequisites, affected component path, or remediation detail beyond fixed build thresholds. Avoid assuming local access, write-path requirements, or broader product impact without vendor confirmation.
Mitigation direction
- Upgrade Acronis Cyber Protect 15 for Windows to build 28035 or later.
- Upgrade Acronis Agent for Windows to build 27305 or later.
- Upgrade Acronis Cyber Protect Home Office for Windows to build 39612 or later.
- Review Acronis SEC-2508 for vendor-specific deployment guidance.
Validation and detection
- Inventory Windows hosts for the named Acronis products.
- Confirm installed build numbers meet or exceed the fixed thresholds.
- Prioritize systems supporting backup, recovery, or endpoint protection operations.
- Document that active exploitation is not evidenced in the provided sources.
