CVE-2023-48382
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 · uneditedSoftnext Mail SQR Expert is an email management platform, it has a Local File Inclusion (LFI) vulnerability in a mail deliver-related URL. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary PHP file with .asp file extension under specific system paths, to access and modify partial system information but does not affect service availability.
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.

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 checksWork through these to decide whether this CVE applies to you.
-
Determine Softnext Mail SQR Expert versionLocate 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)
-
Identify mail delivery endpoint accessibilityLocate 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
-
Verify unauthenticated access to vulnerable parameterTest 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
-
Check for .asp file handling in web server configInspect 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
-
Assess network exposureDetermine 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.

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 · scoped230330
Apply 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.
230330 or later
- 1. Back up the current Mail Sqr Expert configuration and database
- 2. Download Softnext Mail SQR Expert version 230330 or later from the official vendor
- 3. Review the vendor's upgrade documentation for any specific migration procedures
- 4. Install the updated version following the vendor's standard upgrade process
- 5. After upgrade, verify that the LFI vulnerability is no longer exploitable by testing the affected mail delivery-related URL path
- 6. Confirm normal mail flow operations are functioning correctly
