CWE-154: Improper Neutralization of Variable Name Delimiters

ID CWE-154

Abstraction Variant

Structure Simple

Status Incomplete

Number of CVEs 1

The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as variable name delimiters when they are sent to a downstream component.

As data is parsed, an injected delimiter may cause the process to take unexpected actions that result in an attack. Example: "$" for an environment variable.
