An issue was discovered in NagVis 1.9b12. The vulnerability exists due to insufficient filtration of user-supplied data passed to the "nagvis-master/share/userfiles/gadgets/std_table.php" URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.
