MySQL UDF mysql_create_function function directory traversal
| mysql-udf-directory-traversal (21738) |  Medium Risk |
Description:
MySQL is a popular, freely distributed relational database server often used as a back-end for Web sites. MySQL versions 4.0.25, 4.1.13, and 5.0.7-beta when running on Microsoft Windows operating systems could allow a remote attacker to include arbitrary files, caused by a vulnerability in the mysql_create_function function. An attacker could send specially-crafted request using the backslash character (\) to bypass the directory traversal checks and possibly execute arbitrary code on the system.
