Descriptions
The sqlauth module in SimpleSAMLphp before 1.15.2 relies on the MySQL utf8 charset, which truncates queries upon encountering four-byte characters. There might be a scenario in which this allows remote attackers to bypass intended access restrictions.
El módulo sqlauth en SimpleSAMLphp en versiones anteriores a la 1.15.2 confía en el charset utf8 MySQL, que trunca las consultas cuando encuentra caracteres de cuatro bytes. Puede haber un escenario en el que esto permita que los atacantes remotos omitan las restricciones de acceso.
