Vulnerability Data

The Adversarial Robustness Toolbox (ART) thru 1.20.1 contains a command-line argument injection vulnerability in its Kubeflow component (robustness_evaluation_fgsm_pytorch.py). The script uses the unsafe eval() function to parse string values provided via the --clip_values and --input_shape command-line arguments. This allows an…

attacker to inject arbitrary Python code into these arguments, which will be executed when eval() is called. The vulnerability can be exploited remotely if an attacker can control these arguments (e.g., through pipeline configuration or automated scripts), leading to arbitrary code execution on the system running the ART evaluation.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing can discover argument-injection flaws in command-construction code but does not stop their introduction.

Input validation directly stops construction of command strings containing unneutralized delimiters or injected arguments.

Least privilege limits the damage an injected code fragment can perform once executed.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require proper input validation and command construction to prevent argument injection.

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

finds

Security testing can detect argument injection but does not prevent it at the source.

prevents

Secure development lifecycle mandates input validation and command construction practices that directly prevent argument injection.

prevents

Application security requirements include explicit rules for safe command-line argument handling and escaping.

prevents

Secure architecture principles discourage unsafe command invocation patterns and favor safer APIs.

prevents

Secure coding standards explicitly require proper neutralization of command arguments, directly eliminating CWE-88.

none

Change management can catch unsafe command patterns during reviews but is not a direct mitigation.
