Weakness (CWE)

CWE-627: Dynamic Variable Evaluation

Variant Incomplete

In a language where the user can influence the name of a variable at runtime, if the variable names are not controlled, an attacker can read or write to arbitrary variables, or access arbitrary functions.

How to prevent it (3 mitigations)

  1. Implementation

    Refactor the code to avoid dynamic variable evaluation whenever possible.

  2. Implementation

    Use only allowlists of acceptable variable or function names.

  3. Implementation

    For function names, ensure that you are only calling functions that accept the proper number of arguments, to avoid unexpected null arguments.

    Dynamic Variable Evaluation in qiskit-ibm-runtime

    ### Summary An `eval()` method exists `Options._get_program_inputs`. This is bad in any case, but especially bad because `Options` are also used server side, so this has the potential to expose arbitrary code injection in runtime containers, now or at a later…
