A remote attacker authenticated as a localhost can exploit this vulnerability to perform command injection attacks, to execute arbitrary system command, manipulate system or disrupt service.
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 command injection vulnerability due to insufficient filtering of special characters in a specific function. An authenticated remote attacker with localhost access can inject and execute arbitrary system commands through the vulnerable function.

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 installationLocate the Mail SQR Expert installation directory on the system, typically found in the installation folder where the application binaries are storedAffected if The application is installed and running on the system
-
Determine installed versionCheck the application version information, usually accessible via the application interface, About section, or version file in the installation directoryAffected if The installed version is lower than 230330 (versions prior to the March 30, 2023 release)
-
Verify authentication is enabledCheck the application's user authentication configuration to confirm whether local or remote user accounts are activeAffected if Local or remote authentication is enabled, providing an attacker with authenticated access capability
-
Confirm localhost access is permittedReview the application's access control settings to determine if localhost or 127.0.0.1 connections are allowedAffected if The application permits localhost or loopback interface access, which is required for the attack vector
The system is affected if Softnext Mail SQR Expert is installed with a version prior to 230330 and the application allows authenticated access via localhost.

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
Implement strict input validation and sanitization for the affected function, restricting or escaping shell metacharacters (such as ;, |, &, $, backticks, and redirection operators) in user-supplied data before passing to system calls.
Mail SQR Expert version 230330 or later
- 1. Verify current Mail SQR Expert version by checking the application interface or system information
- 2. Download the latest version of Mail SQR Expert (version 230330 or later) from the official vendor or trusted distribution channel
- 3. Create a complete backup of the current Mail SQR Expert configuration, including all settings, email data, and database
- 4. Stop the Mail SQR Expert service before performing the upgrade
- 5. Install the upgraded version (230330 or later) following the vendor's installation documentation
- 6. Restore the configuration backup if needed after installation
- 7. Restart the Mail SQR Expert service
- 8. Verify the upgrade was successful by checking the version information and testing core email functionality
