<plugin_comment>This plugin is not very accurate! You have to verify the existence of the potentially affected Altnet Download-Manager on the host.</plugin_comment>

<bug_not_affected>Altnet Download-Manager newer than 4.0.0.4 or other download managers</bug_not_affected>
<bug_vulnerability_class>Buffer Overflow</bug_vulnerability_class>
<bug_description>The target system may running the peer-to-peer software Kazaa. The popular filesharing clients Kazaa and Grokster also provide a download-manager by Altnet. This is vulnerable to a buffer overflow in the IsValidFile() method in the ADM ActiveX control. An attacker may run arbitrary web code on the target system.</bug_description>
<bug_solution>Disable the peer-to-peer software if not allowed nor needed. If it should run then filter incoming traffic on port tcp/1214 to prevent unwanted access to the web service. Also de-install or de-activate or uphrade the affected Download-Manager by Altnet.</bug_solution>
