CVE-2015-6785 (GCVE-0-2015-6785)

Vulnerability from cvelistv5 – Published: 2015-12-06 01:00 – Updated: 2024-08-06 07:29

Summary

The CSPSource::hostMatches function in WebKit/Source/core/frame/csp/CSPSource.cpp in the Content Security Policy (CSP) implementation in Google Chrome before 47.0.2526.73 accepts an x.y hostname as a match for a *.x.y pattern, which might allow remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging a policy that was intended to be specific to subdomains.

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.
