Vulnerability from github – Published: 2021-05-21 16:24 – Updated: 2023-10-02 12:10

Summary

pomerium_signature is not verified in middleware in github.com/pomerium/pomerium

Details

Impact

Some API endpoints under /.pomerium/ do not verify parameters with pomerium_signature. This could allow modifying parameters intended to be trusted to Pomerium.

The issue mainly affects routes responsible for sign in/out, but does not introduce an authentication bypass.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
