Signature Detail

HTTP: SQL Command In Header Fields (3)

This signature detects a long SQL command sequence in a HTTP request header. Because SQL commands are not normally used in HTTP connections, this can indicate a SQL injection attack. It could, however, be a false positive. To reduce false positives, it is strongly recommended that these signatures only be used to inspect traffic from the Internet to your organization's Web servers that use SQL backend databases to generate content and not to inspect traffic going from your organization to the Internet. Attackers can inject SQL commands using some header fields.
