Descriptions

An issue was discovered in Open-Xchange Server 6 / OX AppSuite before 7.8.0-rev26. The "session" parameter for file-download requests can be used to inject script code that gets reflected through the subsequent status page. Malicious script code can be executed within a trusted domain's context. While no OX App Suite specific data can be manipulated, the vulnerability can be exploited without being authenticated and therefore used for social engineering attacks, stealing cookies or redirecting from trustworthy to malicious hosts.

Ha sido descubierto un problema en Open-Xchange Server 6 / OX AppSuite en versiones anteriores a 7.8.0-rev26. El parámetro "session" para peticiones de descarga de archivos puede emplearse para inyectar código script que se refleja a través de la posterior página de estado. El código script malicioso puede ser ejecutado dentro de un contexto de dominio de confianza. Mientras que ningún dato específico de OX App Suite puede ser manipulado, la vulnerabilidad puede ser explotada sin ser autenticado y por tanto ser utilizada para ataques de ingeniería social, robando cookies o redirigiendo desde hosts confiables a maliciosos.
