Invision NetSupport School Pro uses a weak encryption algorithm to encrypt passwords, which allows local users to obtain passwords.

SQL injection vulnerability in problist.asp in NetSupport DNA HelpDesk 1.01 allows remote attackers to execute arbitrary SQL commands via the where parameter.

NetSupport Manager Client before 10.20.0004 allows remote attackers to bypass the (1) basic and (2) authentication schemes by spoofing the NetSupport Manager.

Buffer overflow in NetSupport Manager (NSM) Client 10.00 and 10.20, and NetSupport School Student (NSS) 9.00, allows remote NSM servers to cause a denial of service or possibly execute arbitrary code via crafted data in the configuration exchange phase of an initial connection setup. NOTE: a vendor statement, which is too vague to be sure that it is for this particular issue, says that only a denial of service is possible.

Stack-based buffer overflow in NetSupport Manager Agent for Linux 11.00, for Solaris 9.50, and for Mac OS X 11.00 allows remote attackers to execute arbitrary code via a long control hostname to TCP port 5405, probably a different vulnerability than CVE-2007-5252.
