Descriptions

The utf8_decode function in PHP before 5.3.4 does not properly handle non-shortest form UTF-8 encoding and ill-formed subsequences in UTF-8 data, which makes it easier for remote attackers to bypass cross-site scripting (XSS) and SQL injection protection mechanisms via a crafted string.

La función utf8_decode en PHP anterior v5.3.4 no maneja adecuadamente la codificación UTF-8 corta y las secuencias malformadas en los datos UTF-8, lo que hace fácil para los atacantes remotos superar los mecanismos de protección en la secuencia de comandos en sitios cruzados (XSS) e inyección de SQL a través de cadenas manipuladas.
