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
The theme.php file in SDCMS 2.8 has a command execution vulnerability that allows for the execution of system commands

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 · high confidence

SDCMS 2.8 contains a command injection vulnerability in theme.php that allows attackers to execute arbitrary system commands on the host server. The vulnerability stems from unsanitized user input being passed to a system call, enabling remote code execution.

MitigationRemediate by implementing strict input validation and sanitization on all user-supplied parameters in theme.php, or refactoring to avoid passing user input to system commands entirely. Apply vendor patch if available.

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 SDCMS installation and version
    Check your web server document root for the presence of SDCMS. Look for version indicators in README files, index.php, or version configuration files. Common locations include the root directory or an 'include' folder.
    Affected if The installed version is SDCMS 2.8 or if the version cannot be determined but the software matches the product name.
  2. Locate theme.php file
    Search for the file theme.php within your SDCMS installation directory. This file is typically found in the admin or template directories.
    Affected if The file theme.php exists in your SDCMS installation.
  3. Inspect theme.php for unsafe system calls
    Open theme.php and search for the presence of PHP system call functions: exec, shell_exec, passthru, and system. Examine whether any of these functions use variables that could contain user-supplied input without proper sanitization.
    Affected if theme.php contains any of these functions (exec, shell_exec, passthru, system) using unsanitized user input from GET, POST, or COOKIE parameters.
  4. Check application network exposure
    Determine if the SDCMS instance is accessible from external networks. Verify firewall rules, network ACLs, or web server access controls that govern who can reach the application.
    Affected if The SDCMS instance is directly accessible from the internet or untrusted networks.

You are affected if you are running SDCMS 2.8 with theme.php present and that file contains unsafe usage of system call functions using user-supplied input.
