HAMweather 3.9.8 - 'template.php' Script Code Injection

source: https://www.securityfocus.com/bid/20311/info

HAMweather is prone to a script-code-injection vulnerability because it fails to sufficiently sanitize user-supplied data.

Exploiting this issue may allow an attacker to compromise the application and the underlying system; other attacks are also possible.

HAMweather 3.9.8.4 and prior versions are vulnerable; other versions may also be affected.
