Novell NetWare

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

The xvesa code in Novell Netware 6.5 SP2 and SP3 allows remote attackers to redirect the xsession without authentication via a direct request to GUIMirror/Start.

Novell NetWare Enterprise Web Server 5.1 and 6.0 allows remote attackers to list directories via a direct request to (1) /com/, (2) /com/novell/, (3) /com/novell/webaccess, or (4) /ns-icons/.

The SSL server implementation in NILE.NLM in Novell NetWare 6.5 and Novell Open Enterprise Server (OES) allows a client to force the server to use weak encryption by stating that a weak cipher is required for client compatibility, which might allow remote attackers to decrypt contents of an SSL protected session.

Unknown vulnerability in Novell GroupWise and GroupWise WebAccess 6.0 through 6.5, when running with Apache Web Server 1.3 for NetWare where Apache is loaded using GWAPACHE.CONF, allows remote attackers to read directories and files on the server.

Novell NetWare with Novell-HTTP-Server or YAWN web servers allows remote attackers to conduct a denial of service via a large number of HTTP GET requests.

The webacc servlet in Novell NetWare Enterprise Web Server 5.1 and 6.0 allows remote attackers to read arbitrary .htt files via a full pathname in the error parameter.

Buffer overflows in the DHCP server for NetWare 6.0 SP1 allow remote attackers to cause a denial of service (reboot) via long DHCP requests.

Multiple buffer overflows in NWFTPD.nlm in the FTP server in Novell NetWare 6.0 before SP4 and 6.5 before SP1 allow remote attackers to cause a denial of service (abend) via a long (1) username or (2) password.

NWFTPD.nlm before 5.02i in the FTP server in Novell NetWare does not properly listen for data connections, which allows remote attackers to cause a denial of service (abend) via multiple FTP sessions.

Unspecified vulnerability in NWFTPD.nlm before 5.03b in the FTP server in Novell NetWare allows remote attackers to cause a denial of service (abend) via a crafted username.

NWFTPD.nlm before 5.06.04 in the FTP server in Novell NetWare allows remote attackers to cause a denial of service (excessive stale connections) by establishing many FTP sessions, which persist in the Not-Logged-In state after each session is completed.

Format string vulnerability in the FTP server for Novell Netware 6.0 SP1 (NWFTPD) allows remote attackers to cause a denial of service (ABEND) via format strings in the USER command.

Novell Netware FTP server NWFTPD before 5.02r allows remote attackers to cause a denial of service (CPU consumption) via a connection to the server followed by a carriage return, and possibly other invalid commands with improper syntax or length.

Netware Enterprise Web Server 5.1 running GroupWise WebAccess 5.5 with Novell Directory Services (NDS) enabled allows remote attackers to enumerate user names, group names and other system information by accessing ndsobj.nlm.

The SSL server implementation in NILE.NLM in Novell NetWare 6.5 and Novell Open Enterprise Server (OES) permits encryption with a NULL key, which results in cleartext communication that allows remote attackers to read an SSL protected session by sniffing network traffic.

Novell NetWare Transaction Tracking System (TTS) in Novell 4.11 and earlier allows remote attackers to cause a denial of service via a large number of requests.

NWFTPD.nlm before 5.01w in the FTP server in Novell NetWare allows remote attackers to cause a denial of service (abend) via an anonymous STOU command.

ICMP redirect messages may crash or lock up a host.

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.

LOGIN.EXE program in Novell Netware 4.0 and 4.01 temporarily writes user name and password information to disk, which could allow local users to gain privileges.

Vulnerability in Novell NetWare 3.x and earlier allows local users to gain privileges via packet spoofing.

Cross-site scripting (XSS) vulnerability in Novell NetWare Enterprise Web Server 5.1 and 6.0 allows remote attackers to process arbitrary script or HTML as other users via (1) a malformed request for a Perl program with script in the filename, (2) the User.id parameter to the webacc servlet, (3) the GWAP.version parameter to webacc, or (4) a URL request for a .bas file with script in the filename.

NWFTPD.nlm in the FTP server in Novell NetWare 6.0 before SP4 and 6.5 before SP1 allows user-assisted remote attackers to cause a denial of service (console hang) via a large number of FTP sessions, which are not properly handled during an NLM unload.

NWFTPD.nlm before 5.04.25 in the FTP server in Novell NetWare does not promptly close DS sessions, which allows remote attackers to cause a denial of service (connection slot exhaustion) by establishing many FTP sessions that persist for the lifetime of a DS session.

The Apache Web Server as used in Novell NetWare 6.5 and GroupWise allows remote attackers to obtain sensitive information via a certain directive to Apache that causes the HTTP-Header response to be modified, which may reveal the server's internal IP address.

ICMP information such as (1) netmask and (2) timestamp is allowed from arbitrary hosts.

PORTAL.NLM in Novell Netware 6.5 SP5 writes the username and password in cleartext to the abend.log log file when the groupOperationsMethod function fails, which allows context-dependent attackers to gain privileges.

NWFTPD.nlm before 5.08.07 in the FTP server in Novell NetWare 6.5 SP7 does not properly implement the FTPREST.TXT NOREMOTE restriction, which allows remote authenticated users to access directories outside of the home server via unspecified vectors.

NWFTPD.nlm before 5.03b in the FTP server in Novell NetWare allows remote authenticated users to cause a denial of service (abend) via a crafted ABOR command.

NWFTPD.nlm before 5.01o in the FTP server in Novell NetWare 5.1 SP3 allows remote authenticated users to cause a denial of service (abend) by sending an RNTO command after a failed RNFR command.

Novell NetWare 6.5 SP 1.1, when installing or upgrading using the Overlay CDs and performing a custom installation with OpenSSH, includes sensitive password information in the (1) NIOUTPUT.TXT and (2) NI.LOG log files, which might allow local users to obtain the passwords.

The Novell Netware client running on Windows 95 allows local users to bypass the login and open arbitrary files via the "What is this?" help feature, which can be launched from the Novell Netware login screen.
