NVD · uneditedSoftnext Mail SQR Expert is an email management platform, it has a Local File Inclusion (LFI) vulnerability in a special 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.
dbcve analysis · moderate confidenceSoftnext Mail SQR Expert contains a Local File Inclusion (LFI) vulnerability allowing unauthenticated remote attackers to access arbitrary PHP files with .asp extension from specific system paths via a specially crafted URL. This enables partial system information disclosure and potential modification without affecting service availability.

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.
-
Identify Softnext Mail SQR Expert versionLocate the software version in the application admin panel, installation directory, or by examining the HTTP server banner if exposed. Compare the installed version against the vulnerable range: any version before 230330 (March 30, 2023) is affected.Affected if The installed version is Softnext Mail SQR Expert and the version number is less than 230330
-
Verify web interface accessibilityDetermine if the Softnext Mail SQR Expert web interface is network-accessible. The LFI vulnerability is exploitable via specially crafted URLs to the web application. Check if external or unauthenticated access is possible.Affected if The web interface is accessible without authentication from an attacker-controlled network location
-
Test for LFI endpoint exposureIdentify if the vulnerable URL endpoint exists and responds to requests. The vulnerability allows accessing .asp extension files from specific system paths via crafted parameters. Check application logs for suspicious access patterns or attempted LFI queries.Affected if The vulnerable URL parameters are exposed and accept user-supplied path input without proper validation
You are affected if running Softnext Mail SQR Expert version below 230330 with the web interface accessible to unauthenticated attackers.
Generated from the published advisory. Verify against your own 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 · scoped230330
Apply vendor-provided security patches when available. Until then, implement network-level access controls or web application firewall rules to restrict access to the vulnerable URL endpoints.
Mail SQR Expert version 230330 or later
- Identify the current installed version of Softnext Mail SQR Expert
- Contact Softnext vendor or consult official release notes to obtain version 230330 or later
- Plan upgrade during maintenance window following vendor upgrade documentation
- Backup current configuration and database before upgrade
- Upgrade to version 230330 or latest stable release
- Verify the upgrade was successful by checking version number
- Test that the vulnerable URL path is no longer accessible without proper authentication
