"value": "Kamailio before 5.4.0, as used in Sip Express Router (SER) in Sippy Softswitch 4.5 through 5.2 and other products, allows a bypass of a header-removal protection mechanism via whitespace characters. This occurs in the remove_hf function in the Kamailio textops module. Particular use of remove_hf in Sippy Softswitch may allow skilled attacker having a valid credential in the system to disrupt internal call start/duration accounting mechanisms leading potentially to a loss of revenue."

"value": "Kamailio versiones anteriores a 5.4.0, como es usado en Sip Express Router (SER) en Sippy Softswitch versiones 4.5 hasta 5.2 y otros productos, permite omitir un mecanismo de protecci\u00f3n de eliminaci\u00f3n de encabezado por medio de caracteres de espacio en blanco. Esto ocurre en la funci\u00f3n remove_hf en el m\u00f3dulo textops de Kamailio. El uso particular de remove_hf en el softswitch Sippy puede permitir a un atacante h\u00e1bil con una credencial v\u00e1lida en el sistema interrumpir los mecanismos internos de contabilidad de inicio/duraci\u00f3n de llamadas, lo que puede dar lugar a una p\u00e9rdida de ingresos"
