PYSEC-2023-178

Vulnerability from pysec - Published: 2023-09-21 15:15 - Updated: 2023-10-28 20:22

Details

plone.rest allows users to use HTTP verbs such as GET, POST, PUT, DELETE, etc. in Plone. Starting in the 2.x branch and prior to versions 2.0.1 and 3.0.1, when the ++api++ traverser is accidentally used multiple times in a url, handling it takes increasingly longer, making the server less responsive. Patches are available in plone.rest 2.0.1 and 3.0.1. Series 1.x is not affected. As a workaround, one may redirect /++api++/++api++ to /++api++ in one's frontend web server (nginx, Apache).

Severity

7.5 (High)

  "details": "### Impact\nWhen the `++api++` traverser is accidentally used multiple times in a url, handling it takes increasingly longer, making the server less responsive.\n\n### Patches\nPatches will be released in `plone.rest` 2.0.1 and 3.0.1.  Series 1.x is not affected.\n\n### Workarounds\nIn your frontend web server (nginx, Apache) you can redirect `/++api++/++api++` to `/++api++`.",

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.
