Novell NetWare 6.5 before Support Pack 8, when an OES2 Linux server is installed into the NDS tree, does not require a password for the ApacheAdmin console, which allows remote attackers to reconfigure the Apache HTTP Server via console operations.

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.

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 NDS_ADM account that is not in the NT domain but has domain access rights, which allows the user to enter a null password.

Novell NetWare 5.0 allows remote attackers to cause a denial of service by flooding port 40193 with random data.

Netscape Enterprise Server in NetWare 5.1 allows remote attackers to cause a denial of service or execute arbitrary commands via a malformed URL.

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.
