Novell 5 and earlier, when running over IPX with a packet signature level less than 3, allows remote attackers to gain administrator privileges by spoofing the MAC address in IPC fragmented packets that make NetWare Core Protocol (NCP) calls.

Novell Netware 5.0 through 5.1 may allow local users to gain "Domain Admin" rights by logging into a Novell Directory Services (NDS) account, and executing "net use" on an NDSADM account that is not in the NT domain but has domain access rights, which allows the user to enter a null password.

Novell NetWare 5.1 installs sample applications that allow remote attackers to obtain sensitive information via (1) ndsobj.nlm, (2) allfield.jse, (3) websinfo.bas, (4) ndslogin.pl, (5) volscgi.pl, (6) lancgi.pl, (7) test.jse, or (8) env.pl.

Stack-based buffer overflow in the CIFS.NLM driver in Netware SMB 1.0 for Novell Netware 6.5 SP8 and earlier allows remote attackers to execute arbitrary code via a Sessions Setup AndX packet with a long AccountName.
