Official description

Multiple plugins for WordPress by emarket-design with the 'emd-form-builder-lite' package are vulnerable to Remote Code Execution in various versions via the emd_form_builder_lite_pagenum function. This is due to the plugin not properly validating user input before using it as a function name. This makes it possible for unauthenticated attackers to execute code on the server, however, parameters can not be passed to the functions called

The underlying weakness: Improper Neutralization of Directives in Dynamically Evaluated Code

The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. eval).

How developers prevent this class of flaw

  • If possible, refactor your code so that it does not need to use eval() at all.
  • For Python programs, it is frequently encouraged to use the ast.literal_eval() function instead of eval, since it is intentionally designed to avoid executing code. However, an adversary could still cause excessive memory or stack consumption via deeply nested structures, so the python documentation discourages use of ast.literal_eval() on untrusted data.
