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
SolarView Compact ver.6.00 was discovered to contain a command injection vulnerability via conf_mail.php.

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

SolarView Compact version 6.00 contains a command injection vulnerability in conf_mail.php that allows remote attackers to execute arbitrary operating system commands via unspecified vectors. The critical CVSS score of 9.8 indicates the vulnerability is easily exploitable and results in complete compromise of the affected system.

MitigationApply input validation and sanitization to all user-supplied parameters in conf_mail.php, or upgrade to a patched version if available from the vendor. Consider network segmentation to limit exposure of the SolarView interface.

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 the SolarView Compact device model
    Check the device model or firmware identification - look for Contec Sv Cpt Mc310 or SolarView Compact in system information or device identification pages
    Affected if Device model is Contec Sv Cpt Mc310
  2. Check the firmware version
    Access the device's firmware version information page or check via administrative interface - typically found in system status, about page, or via SNMP/sysinfo query
    Affected if Firmware version is exactly 6.00
  3. Verify conf_mail.php is accessible
    Attempt to access the URI /conf_mail.php or /php/conf_mail.php on the SolarView web interface - this is the vulnerable script
    Affected if conf_mail.php is accessible and responds to HTTP requests
  4. Check if mail configuration feature is enabled
    Examine the SolarView web interface for mail/email configuration settings - look for SMTP configuration, email notification, or mail server settings in the admin panel
    Affected if Mail configuration feature is enabled and accessible to unauthenticated or low-privileged users
  5. Identify exposed email input parameters
    Review the HTTP requests when accessing conf_mail.php - look for email-related POST/GET parameters that accept user input for SMTP server, sender, recipient, or subject fields
    Affected if The page accepts unsanitized user input in email configuration parameters

A system is affected if it is a Contec Sv Cpt Mc310 device running SolarView Compact firmware version 6.00 with the conf_mail.php mail configuration interface exposed and accessible.

Mitigation

Apply input validation and sanitization to all user-supplied parameters in conf_mail.php, or upgrade to a patched version if available from the vendor. Consider network segmentation to limit exposure of the SolarView interface.
