Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Sensitive information disclosure due to CORS misconfiguration. The following products are affected: Acronis Cyber Infrastructure (ACI) before build 5.2.0-135.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Cross-Origin Resource Sharing (CORS) misconfiguration in Acronis Cyber Infrastructure allows unauthorized cross-origin requests to access sensitive resources. The CORS policy is set too permissively, potentially allowing malicious websites to make authenticated requests on behalf of users and exfiltrate sensitive data.

MitigationRestrict CORS policy to explicitly allow only trusted origins, and avoid using wildcard (*) origins or overly broad Access-Control-Allow-Origin headers. Upgrade to ACI build 5.2.0-135 or later.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Acronis Cyber Infrastructure is installed
    Check for the ACI service or installation directory - look for /opt/acronis/cyber-infrastructure or run 'systemctl list-units | grep -i acronis' to find running ACI services
    Affected if The product is present on the system
  2. Verify the installed ACI version
    Run the ACI version command or check /opt/acronis/cyber-infrastructure/version file if it exists - compare the build number to 5.2.0-135
    Affected if The installed version is less than 5.2.0-135 (build 135)
  3. Locate the CORS configuration
    Search for CORS-related configuration files - check nginx/apache config directories under /etc/nginx/, /etc/httpd/, or the ACI web server config directory for files containing 'access-control-allow-origin' or 'cors' directives
    Affected if CORS configuration files exist in the web server setup
  4. Inspect Access-Control-Allow-Origin headers
    Examine the CORS configuration files for the Access-Control-Allow-Origin directive - look for wildcard (*) value, missing origin validation, or overly broad origin patterns
    Affected if The Access-Control-Allow-Origin is set to wildcard (*) or allows unrestricted origins
  5. Check CORS allowed origins list
    Review the CORS configuration to determine if origins are explicitly whitelisted or if the policy permits any origin to make cross-origin requests
    Affected if Origins are not explicitly restricted to trusted domains or the policy is overly permissive

The environment is affected if Acronis Cyber Infrastructure is installed with a version earlier than 5.2.0-135 AND the CORS policy permits wildcard or unspecified origins in the Access-Control-Allow-Origin configuration.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 5.2.0-135 or later
Fixed in 5.2.0-135
Interim mitigation

Restrict CORS policy to explicitly allow only trusted origins, and avoid using wildcard (*) origins or overly broad Access-Control-Allow-Origin headers. Upgrade to ACI build 5.2.0-135 or later.

Recommended fix Moderate confidence

Acronis Cyber Infrastructure build 5.2.0-135 or later

  1. 1. Back up the current Acronis Cyber Infrastructure configuration and data
  2. 2. Obtain the updated Acronis Cyber Infrastructure build 5.2.0-135 or later from official Acronis distribution channels
  3. 3. Follow Acronis standard upgrade documentation for your deployment type (standalone or cluster)
  4. 4. After upgrade, verify the CORS configuration is properly restricted to trusted domains only
  5. 5. Test that the application functions normally with the corrected CORS policy
Caveat Review Acronis upgrade documentation for any migration requirements between your current version and 5.2.0
