Descriptions

In Roundcube Webmail before 1.3.10, an attacker in possession of S/MIME or PGP encrypted emails can wrap them as sub-parts within a crafted multipart email. The encrypted part(s) can further be hidden using HTML/CSS or ASCII newline characters. This modified multipart email can be re-sent by the attacker to the intended receiver. If the receiver replies to this (benign looking) email, they unknowingly leak the plaintext of the encrypted message part(s) back to the attacker.

En Roundcube Webmail en versiones anteriores a la 1.3.10, un atacante en posesión de correos electrónicos cifrados S/MIME o PGP puede envolverlos como subparte dentro de un correo electrónico multiparte diseñado. La(s) parte(s) encriptada(s) puede ocultarse aún más usando caracteres HTML/CSS o de nueva línea ASCII. El atacante puede reenviar este correo electrónico multiparte modificado al destinatario previsto. Si el destinatario responde a este correo electrónico (de aspecto benigno), sin saberlo, filtra el texto plano de la(s) parte(s) del mensaje cifrado al atacante.
