GSD-2020-8163

Vulnerability from gsd - Updated: 2020-05-15 00:00

Details

There was a vulnerability in versions of Rails prior to 5.0.1 that would allow an attacker who controlled the `locals` argument of a `render` call. Versions Affected: rails < 5.0.1 Not affected: Applications that do not allow users to control the names of locals. Fixed Versions: 4.2.11.2 Impact ------ In the scenario where an attacker might be able to control the name of a local passed into `render`, they can acheive remote code execution. Workarounds ----------- Until such time as the patch can be applied, application developers should ensure that all user-provided local names are alphanumeric.

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.
