During internal penetration testing of a product based on Yii2, users discovered a Cross-site Scripting (XSS) vulnerability within the framework itself. This issue is relevant for the latest version of Yii2 (2.0.49.3). This issue lies in the mechanism for displaying function argument values in the stack trace. The vulnerability manifests when an argument's value exceeds 32 characters. For convenience, argument values exceeding this limit are truncated and displayed with an added \"...\". The full argument value becomes visible when hovering over it with the mouse, as it is displayed in the title attribute of a span tag. However, the use of a double quote (\") allows an attacker to break out of the title attribute's value context and inject their own attributes into the span tag, including malicious JavaScript code through event handlers such as onmousemove. This vulnerability allows an attacker to execute arbitrary JavaScript code in the security context of the victim's site via a specially crafted link. This could lead to the theft of cookies (including httpOnly cookies, which are accessible on the page), content substitution, or complete takeover of user accounts. This issue has been addressed in version 2.0.50. Users are advised to upgrade. There are no known workarounds for this vulnerability."}, {"lang": "es", "value": "Yii 2 es un framework de aplicaci\u00f3n PHP. Durante las pruebas de penetraci\u00f3n interna de un producto basado en Yii2, los usuarios descubrieron una vulnerabilidad de Cross-site Scripting (XSS) dentro del propio framework. Este problema es relevante para la \u00faltima versi\u00f3n de Yii2 (2.0.49.3). Este problema radica en el mecanismo para mostrar los valores de los argumentos de la funci\u00f3n en el seguimiento de la pila. La vulnerabilidad se manifiesta cuando el valor de un argumento supera los 32 caracteres. Por conveniencia, los valores de argumento que exceden este l\u00edmite se truncan y se muestran con un \"...\" agregado. El valor completo del argumento se vuelve visible al pasar el mouse sobre \u00e9l, tal como se muestra en el atributo de t\u00edtulo de una etiqueta de extensi\u00f3n. Sin embargo, el uso de una comilla doble (\"\") permite a un atacante salir del contexto de valor del atributo de t\u00edtulo e inyectar sus propios atributos en la etiqueta span, incluido c\u00f3digo JavaScript malicioso a trav\u00e9s de controladores de eventos como onmousemove. Esta vulnerabilidad permite a un atacante ejecutar c\u00f3digo JavaScript arbitrario en el contexto de seguridad del sitio de la v\u00edctima a trav\u00e9s de un enlace especialmente manipulado. Esto podr\u00eda provocar el robo de cookies (incluidas las cookies httpOnly, a las que se puede acceder en la p\u00e1gina), la sustituci\u00f3n de contenido o la toma completa de cuentas de usuario. El problema se solucion\u00f3 en la versi\u00f3n 2.0.50. Se recomienda a los usuarios que actualicen. No existen workarounds para esta vulnerabilidad."}], "lastModified": "2024-05-31T13:01:46.727", "sourceIdentifier": "security-advisories@github.com"}
