Descriptions

An issue was discovered in DAViCal Andrew's Web Libraries (AWL) through 0.60. Session management does not use a sufficiently hard-to-guess session key. Anyone who can guess the microsecond time (and the incrementing session_id) can impersonate a session.

Se descubrió un problema en DAViCal Andrew's Web Libraries (AWL) versiones hasta el 0,60. La administración de sesiones no usa una clave de sesión lo suficientemente difícil de adivinar. Cualquiera que pueda adivinar el tiempo de microsegundos (y el incremento del session_id) puede suplantar una sesión.
