CVE-2024-4748
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 · uneditedThe CRUDDIY project is vulnerable to shell command injection via sending a crafted POST request to the application server. The exploitation risk is limited since CRUDDIY is meant to be launched locally. Nevertheless, a user with the project running on their computer might visit a website which would send such a malicious request to the locally launched server.
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 confidenceThe CRUDDIY application contains a shell command injection vulnerability where unsanitized user input from POST requests is passed to system shell commands, allowing arbitrary command execution.

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 if J11g Cruddiy is deployedCheck the application's source files for the Cruddiy branding, copyright notices, or the presence of a file named 'cruddiy' or similar in the web root directory.Affected if The application is J11g Cruddiy and handles user-submitted data via web forms.
-
Determine the installed versionLocate a version file, changelog, or the main application entry point and look for a version string. Common locations include a 'version.php' file, 'README' file, or the main index file header comments.Affected if The version is 202312.1 or any earlier version.
-
Locate POST request handlersSearch the application source code for PHP files that process $_POST variables. Look for files containing '$_POST' array access, particularly those in controllers, handlers, or action files.Affected if The application accepts user input via HTTP POST requests to any endpoint.
-
Identify shell command execution with POST dataSearch PHP source files for shell execution functions (shell_exec, exec, system, passthru, or backtick operator) combined with direct concatenation of $_POST, $_REQUEST, or similar user input arrays.Affected if Code passes unsanitized POST parameters directly into shell command functions without using escapeshellarg or escapeshellcmd.
-
Inspect the vulnerable code patternReview files identified in step 4. Look for patterns where POST parameters are appended to command strings, such as: shell_exec("command " . $_POST['param']), exec("command $variable"), or similar constructions.Affected if The application executes shell commands using user-supplied POST data without input validation or proper escaping.
If J11g Cruddiy version 202312.1 or earlier is running and the codebase contains PHP files that pass $_POST variables directly to shell execution functions, the environment is affected by this vulnerability.

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.
From vendor dataImplement strict input validation and avoid shell command execution with user-supplied data; use parameterized commands or safe APIs instead of passing input directly to shell functions.
