Descriptions

The nsCSPContext::SendReports function in dom/security/nsCSPContext.cpp in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 does not prevent use of a non-HTTP report-uri for a Content Security Policy (CSP) violation report, which allows remote attackers to cause a denial of service (data overwrite) or possibly gain privileges by specifying a URL of a local file.

La función nsCSPContext::SendReports en dom/security/nsCSPContext.cpp en Mozilla Firefox en versiones anteriores a 45.0 y Firefox ESR 38.x en versiones anteriores a 38.7 no previene el uso de una URL de informe no HTTP para un informe de violación de Content Security Policy (CSP), lo que permite a atacantes remotos causar una denegación de servicio (sobreescripción de datos) o posiblemente ganar privilegios especificando el URL de un archivo local."
