What is CVE-2007-3923?

The Cisco Wide Area Application Services (WAAS) software, specifically versions 4.0.7 and 4.0.9, contains a vulnerability in its Common Internet File System (CIFS) optimization feature. When Edge Services are configured, this flaw allows remote attackers to exploit the system by flooding it with TCP SYN packets directed at ports 139 and 445. This can lead to a denial of service, effectively rendering network services inaccessible and causing significant disruption to operations.
