Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Lynx, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The lynx gem prior to 1.0.0 for Ruby places the configured password on command lines, which allows local users to obtain sensitive information by listing processes. As of version 1.0.0, lynx no longer supports a `--password` option. Passwords are only configured in a configuration file, so it's no longer possible to expose passwords on the command line.
