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 Github.com/pomerium/pomerium, 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

### Impact In distributed service mode, Pomerium's Authenticate service exposes pprof debug and prometheus metrics handlers to untrusted traffic. This can leak potentially sensitive environmental information or lead to limited denial of service conditions. ### Patches v0.17.1 ### Workarounds Block access to `/debug` and `/metrics` paths on the authenticate service. This can be done with any L7 proxy, including Pomerium's own proxy service. ### References https://github.com/pomerium/pomerium/pull/3212 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Pomerium](https://github.com/pomerium/pomerium) * Email us at [security@pomerium.com](mailto:security@pomerium.com)
