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
The vulnerability allows a remote unauthenticated attacker to read arbitrary content of the results database via a crafted HTTP request.

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 · moderate confidence

This is an information disclosure vulnerability in a web application's database layer. An unauthenticated remote attacker can send specially crafted HTTP requests to read arbitrary content from a 'results database,' indicating a failure in access control or input validation that protects database queries.

MitigationImplement proper authentication and authorization checks for all database access paths, and validate/sanitize HTTP request parameters to prevent unauthorized query manipulation.

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 installed Bosch Nexo Os version
    Locate the version information for your Bosch Nexo Os installation through the system administration interface, firmware metadata, or product documentation. Common locations include the web management console, system info panel, or firmware file naming.
    Affected if The installed version falls within the range >= 1000 and <= 1500-sp2
  2. Confirm web application is accessible
    Verify that the web interface or API endpoints for the Bosch Nexo Os application are exposed and reachable via HTTP/HTTPS from network locations where an unauthenticated attacker could reach them.
    Affected if The web application is accessible to unauthenticated users on the network without requiring credentials
  3. Test results database access path
    Send crafted HTTP requests to potential database query endpoints, particularly those related to a 'results database' feature, without providing authentication credentials. Observe if the application returns database content or sensitive information without authorization checks.
    Affected if The application returns database records or arbitrary content from the results database to unauthenticated requests
  4. Review access control configuration
    Inspect the application's configuration files, web server settings, or authentication module to determine whether database query endpoints enforce proper authorization for all user roles, including unauthenticated access.
    Affected if Access controls for database query paths are missing, misconfigured, or allow unauthenticated access to sensitive data
  5. Analyze HTTP request parameter handling
    Examine how the application processes HTTP request parameters that may influence database queries. Test with malformed or manipulated input to see if the application validates and sanitizes parameters before executing database operations.
    Affected if The application fails to validate or sanitize HTTP request parameters used in database queries, allowing injection or manipulation of query logic

The environment is affected if the installed Bosch Nexo Os version is between 1000 and 1500-sp2 inclusive AND the web application allows unauthenticated access to results database queries via HTTP requests.

Upgrade available Upgrade to a release after 1500-sp2
Interim mitigation

Implement proper authentication and authorization checks for all database access paths, and validate/sanitize HTTP request parameters to prevent unauthorized query manipulation.

Recommended fix Moderate confidence

Contact Bosch for the specific fixed release (version > 1500-sp2)

  1. 1. Identify the current installed version of Nexo OS by accessing the system administration interface or checking system documentation.
  2. 2. If the installed version is between 1000 and 1500-sp2 (inclusive), the system is vulnerable to CVE-2023-48259.
  3. 3. Contact Bosch Nexo OS vendor to obtain the latest patched version that addresses this SQL injection vulnerability.
  4. 4. Plan the upgrade during a maintenance window, ensuring proper backups of configuration and data.
  5. 5. Apply the upgrade following Bosch vendor-provided installation instructions.
  6. 6. After upgrade, verify the system is running the patched version and confirm the vulnerability is resolved.
