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.

ACLCHECK module in Novell iChain 2.3 allows attackers to bypass access control rules of an unspecified component via an unspecified attack vector involving a string that contains escape sequences represented with "overlong UTF-8 encoding."

Cross-site scripting (XSS) vulnerability in Novell iChain 2.3 allows remote attackers to obtain login credentials via unspecified vectors.

Novell iChain 2.3 allows attackers to cause a denial of service via a URL with a "specific string."
