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
A Remote Code Execution (RCE) vulnerability was found in Smanga 3.2.7 in the /php/path/rescan.php interface. The application fails to properly sanitize user-supplied input in the mediaId parameter before using it in a system shell command. This allows an unauthenticated attacker to inject arbitrary operating system commands, leading to complete server compromise.

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

Smanga 3.2.7 contains a command injection vulnerability in /php/path/rescan.php where the mediaId parameter is passed directly to a shell execution function without sanitization. An unauthenticated attacker can append OS commands to the parameter value, achieving arbitrary code execution on the underlying server.

MitigationImmediately restrict network access to the rescan.php endpoint pending a patch. The fix requires implementing input validation (whitelist approach) and refactoring code to avoid shell execution, replacing system() or exec() calls with safe alternatives.

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. Confirm Smanga installation
    Locate the Smanga application on the server by searching for characteristic directories or files such as 'smanga', 'comic', or 'manga' in the web root or application directories.
    Affected if Smanga software is present on the server
  2. Identify the installed version
    Check the version information for Smanga, typically found in a version file, about page, or application metadata within the installation directory.
    Affected if The installed version is exactly 3.2.7
  3. Locate the vulnerable script
    Search for the file rescan.php within the Smanga installation directory structure, particularly under a /php/ subdirectory.
    Affected if The file rescan.php exists in the Smanga installation
  4. Verify mediaId parameter acceptance
    Inspect the rescan.php script source code to confirm it accepts a mediaId parameter and passes it to a shell execution function such as system(), exec(), or shell_exec().
    Affected if The script contains code that executes the mediaId parameter without sanitization
  5. Assess network exposure
    Determine if the rescan.php endpoint is accessible from the network, typically by checking web server configuration and firewall rules.
    Affected if The endpoint is reachable from untrusted networks without authentication

You are affected if Smanga version 3.2.7 is installed and the rescan.php script that processes the mediaId parameter is present and accessible.

Mitigation

Immediately restrict network access to the rescan.php endpoint pending a patch. The fix requires implementing input validation (whitelist approach) and refactoring code to avoid shell execution, replacing system() or exec() calls with safe alternatives.
