This module exploits a stack based buffer overflow in Watermark Master 2.2.23 when
|
|
processing a specially crafted .WCF file. This vulnerability could be
|
|
exploited by a remote attacker to execute arbitrary code on the target
|
|
machine by enticing a user of Watermark Master to open a malicious .WCF file.
