Descriptions
phlex is an open source framework for building object-oriented views in Ruby. There is a potential cross-site scripting (XSS) vulnerability that can be exploited via maliciously crafted user data. The filter to detect and prevent the use of the `javascript:` URL scheme in the `href` attribute of an `<a>` tag could be bypassed with tab `\t` or newline `
` characters between the characters of the protocol, e.g. `java\tscript:`. This vulnerability is fixed in 1.10.1, 1.9.2, 1.8.3, 1.7.2, 1.6.3, 1.5.3, and 1.4.2. Configuring a Content Security Policy that does not allow `unsafe-inline` would effectively prevent this vulnerability from being exploited.
Phlex es un framework de código abierto para crear vistas orientadas a objetos en Ruby. Existe una posible vulnerabilidad de cross-site scripting (XSS) que puede explotarse mediante datos de usuario creados con fines malintencionados. El filtro para detectar y evitar el uso del esquema de URL `javascript:` en el atributo `href` de una etiqueta `<a rel="nofollow">` podría omitirse con tabulaciones `\t` o caracteres de nueva línea `
` entre los caracteres de el protocolo, por ejemplo `java\tscript:`. Esta vulnerabilidad se solucionó en 1.10.1, 1.9.2, 1.8.3, 1.7.2, 1.6.3, 1.5.3 y 1.4.2. Configurar una política de seguridad de contenido que no permita "inseguro en línea" evitaría efectivamente que se aproveche esta vulnerabilidad.</a>
