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

Softnext Mail SQR Expert contains a Local File Inclusion (LFI) vulnerability in a mail delivery-related URL. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary PHP files with .asp file extension located under specific system paths, potentially allowing access and modification of partial system information. The vulnerability does not affect service availability.

MitigationApply vendor-provided patches or updates for Softnext Mail SQR Expert. If no patch is available, implement strict input validation and path sanitization on mail delivery-related endpoints, restrict file access permissions, and consider web application firewall rules to mitigate LFI attacks.

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. Determine Softnext Mail SQR Expert version
    Locate the installation directory and check the version file, or access the admin interface version information page. Common paths include the installation root or help/about sections.
    Affected if Installed version is lower than 230330 (any version before March 30, 2023)
  2. Identify mail delivery endpoint accessibility
    Locate and inspect the mail delivery-related URL endpoint in the web application. This is typically found in the mail gateway or relay configuration area.
    Affected if The mail delivery endpoint is exposed and accessible without authentication
  3. Verify unauthenticated access to vulnerable parameter
    Test the mail delivery URL with a basic LFI probe (such as referencing a known file under system paths like ../../) without providing credentials.
    Affected if The endpoint accepts path traversal parameters without requiring authentication
  4. Check for .asp file handling in web server config
    Inspect the web server or application configuration to confirm that PHP files with .asp extension are allowed to be processed.
    Affected if The server is configured to execute PHP files with .asp extensions in the affected system paths
  5. Assess network exposure
    Determine if the mail web interface is accessible from untrusted networks or the internet.
    Affected if The Softnext Mail SQR Expert web interface is directly exposed to the internet or untrusted networks

A system is affected if it runs Softnext Mail SQR Expert version below 230330 and has the mail delivery-related endpoint accessible to unauthenticated users.
