CVE-2017-14143

The getUserzoneCookie function in Kaltura before 13.2.0 uses a hardcoded cookie secret to validate cookie signatures, which allows remote attackers to bypass an intended protection mechanism and consequently conduct PHP object injection attacks and execute arbitrary PHP code via a crafted userzone cookie.

The getUserzoneCookie function in Kaltura before 13.2.0 uses a hardcoded cookie secret to validate cookie signatures, which allows remote attackers to bypass an intended protection mechanism and consequently conduct PHP object injection attacks and execute arbitrary PHP code via a crafted userzone cookie.

La función getUserzoneCookie en Kaltura en versiones anteriores a la 13.2.0 emplea un secreto de cookie embebido para validar firmas de cookies. Esto permite que los atacantes remotos omitan un mecanismo de protección previsto y que lleven a cabo ataques de inyección de objetos PHP y ejecuten código PHP arbitrario mediante una cookie userzone manipulada.
