Security readout for executives and security teams
Plain-English summary
Acronis Agent could write sensitive information into logs on Windows, Linux, and macOS before build 27147. The business risk is unintended disclosure through log access, backups, or log aggregation. The provided sources do not include severity scoring or detailed data types.
Executive priority
Treat this as a data-exposure hygiene issue. Prioritize upgrades and log access review where Acronis Agent runs on sensitive systems or logs are widely distributed.
Technical view
CVE-2021-34800 is a CWE-532 sensitive information logging issue affecting Acronis Agent before build 27147 across Windows, Linux, and macOS. The source bundle does not provide CVSS details, exploit prerequisites, or specific logged secrets.
Likely exposure
Organizations using Acronis Agent builds earlier than 27147 on Windows, Linux, or macOS may be exposed, especially where endpoint logs are broadly accessible or centrally collected.
Exploitation context
The source bundle does not state active exploitation, and KEV is false. Risk depends on whether sensitive log entries exist and who can access those logs.
Researcher notes
Evidence is limited to the CVE record and Acronis advisory reference. No CVSS vector, affected configuration detail, exploit status, or specific sensitive data classes are provided in the bundle.
Mitigation direction
- Upgrade Acronis Agent to build 27147 or later where supported.
- Review Acronis advisory SEC-3145 for vendor-specific remediation guidance.
- Restrict access to endpoint and centralized Acronis logs.
- Handle existing logs as potentially sensitive until reviewed.
Validation and detection
- Inventory Acronis Agent installations and record installed build numbers.
- Confirm all agents are build 27147 or later.
- Review log storage locations and access permissions.
- Check whether older logs were collected into SIEM or backup systems.

Insertion of Sensitive Information into Log File
Insertion of Sensitive Information into Log File represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
