Descriptions

The CSPSourceList::matches function in WebKit/Source/core/frame/csp/CSPSourceList.cpp in the Content Security Policy (CSP) implementation in Google Chrome before 47.0.2526.73 accepts a blob:, data:, or filesystem: URL as a match for a * pattern, which allows remote attackers to bypass intended scheme restrictions in opportunistic circumstances by leveraging a policy that relies on this pattern.

La función CSPSourceList::matches en WebKit/Source/core/frame/csp/CSPSourceList.cpp en la implementación de la Content Security Policy (CSP) en Google Chrome en versiones anteriores a 47.0.2526.73 acepta una URL blob:, data: o filesystem: como coincidencia para un patrón *, lo que permite a atacantes remotos eludir las restricciones de esquema previstas en circunstancias oportunistas mediante el aprovechamiento de una política que confía en éste patrón.
