Novell iChain 2.2

The web GUI for Novell iChain 2.2 and 2.3 SP2 and SP3 allows attackers to hijack sessions and gain administrator privileges by (1) sniffing the connection on TCP port 51100 and replaying the authentication information or (2) obtaining and replaying the PCZQX02 authentication cookie from the browser.

Novell iChain Mini FTP Server 2.3, and possibly earlier versions, does not limit the number of incorrect logins, which makes it easier for remote attackers to conduct brute force login attacks.

Novell iChain 2.2 before Support Pack 1 does not properly verify that URL redirects match the DNS name of an accelerator, which allows attackers to redirect URLs to malicious web sites.

The Mini FTP server in Novell iChain 2.2 and 2.3 SP2 and earlier allows remote unauthenticated attackers to obtain the full path of the server via the PWD command.

Novell iChain 2.2 before Support Pack 1 uses a shorter timeout for a non-existent user than a valid user, which makes it easier for remote attackers to guess usernames and conduct brute force password guessing.

Novell iChain Mini FTP Server 2.3 displays different error messages if a user exists or not, which allows remote attackers to obtain sensitive information and facilitates brute force attacks.

Unknown vulnerability or vulnerabilities in Novell iChain 2.2 before Support Pack 1, with unknown impact, possibly related to unauthorized access to (1) NCPIP.NLM and (2) JSTCP.NLM.
