Affected version: DedeCMS V5.7.110
Vulnerability description: dedecms's tag query interface has SQL injection, using the variable $tag_alias to interpolate strings in SQL query statements,
and does not perform any filtering or escape processing on $tag_alias. This allows malicious users to inject malicious SQL code by constructing specific URL parameters.
Attackers can use this to steal sensitive information such as databases.
