- CWE version
- 5.0
Description
The product invokes a generative AI/ML
component whose behaviors and outputs cannot be directly
controlled, but the product does not validate or
insufficiently validates the outputs to ensure that they
align with the intended security, content, or privacy
policy.
Common consequences
• Integrity: Execute Unauthorized Code or Commands, Varies by Context — In an agent-oriented setting,
output could be used to cause unpredictable agent
invocation, i.e., to control or influence agents
that might be invoked from the output. The impact
varies depending on the access that is granted to
the tools, such as creating a database or writing
files.
Potential mitigations
• [Architecture and Design] Since the output from a generative AI component (such as an LLM) cannot be trusted, ensure that it operates in an untrusted or non-privileged space.
• [Operation] Use "semantic comparators," which are mechanisms that
provide semantic comparison to identify objects that might appear
different but are semantically similar.
• [Operation] Use components that operate
externally to the system to monitor the output and
act as a moderator. These components are called
different terms, such as supervisors or
guardrails.
• [Build and Compilation] During model training, use an appropriate variety of good
and bad examples to guide preferred outputs.
Detection methods
• Dynamic Analysis with Manual Results Interpretation: Use known techniques for prompt injection
and other attacks, and adjust the attacks to be more
specific to the model or system.
• Dynamic Analysis with Automated Results Interpretation: Use known techniques for prompt injection
and other attacks, and adjust the attacks to be more
specific to the model or system.
• Architecture or Design Review: Review of the product design can be
effective, but it works best in conjunction with dynamic
analysis.
Observed examples
• CVE-2024-3402: Chain: GUI for ChatGPT API performs
input validation but does not properly "sanitize"
or validate model output data (CWE-1426), leading
to XSS (CWE-79).
