SQL injection vulnerability in catalog/index.shtml in 4site CMS 2.6, and possibly earlier, allows remote attackers to execute arbitrary SQL commands via the cat parameter. NOTE: the i and th vectors are already covered by CVE-2009-0646.
Improper Neutralization of Special Elements used in an SQL Command The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
