Descriptions

In WS_FTP Server version prior to 8.8.2, a stored cross-site scripting (XSS) vulnerability exists in WS_FTP Server's Management module. An attacker with administrative privileges could import a SSL certificate with malicious attributes containing cross-site scripting payloads.  Once the cross-site scripting payload is successfully stored,  an attacker could leverage this vulnerability to target WS_FTP Server admins with a specialized payload which results in the execution of malicious JavaScript within the context of the victims browser.

En la versión del servidor WS_FTP anterior a la 8.8.2, existe una vulnerabilidad de Cross-Site Scripting (XSS) almacenada en el módulo de administración del servidor WS_FTP. Un atacante con privilegios administrativos podría importar un certificado SSL con atributos maliciosos que contengan payloads de Cross-Site Scripting. Una vez que el payload de Cross-Site Scripting se almacena con éxito, un atacante podría aprovechar esta vulnerabilidad para atacar a los administradores del servidor WS_FTP con un payload especializado que resulta en la ejecución de JavaScript malicioso dentro del contexto del navegador de la víctima.
