Descriptions

An issue was discovered in Roundcube Webmail before 1.3.12 and 1.4.x before 1.4.5. There is XSS via a malicious XML attachment because text/xml is among the allowed types for a preview.

Se detectó un problema en Roundcube Webmail versiones anteriores a 1.3.12. Se presenta una vulnerabilidad de tipo XSS por medio de un archivo adjunto XML malicioso porque text/xml se encuentra entre los tipos permitidos para una vista previa

Matei Badanoiu and LoRexxar@knownsec discovered that roundcube, a skinnable AJAX based webmail solution for IMAP servers, did not correctly process and sanitize requests. This would allow a remote attacker to perform a Cross-Side Scripting (XSS) attack leading to the execution of arbitrary code.

Roundcube Webmail contains a cross-site scripting (XSS) vulnerability that allows a remote attacker to manipulate data via a malicious XML attachment.
