Novell » Ichain : Security Vulnerabilities, CVEs, CVSS score >= 7

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.

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.

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."

The Telnet listener for Novell iChain Server before 2.2 Field Patch 3b 2.2.116 does not have a password by default, which allows remote attackers to gain access.

Multiple buffer overflows in Novell iChain 2.1 before Field Patch 3, and iChain 2.2 before Field Patch 1a, allow attackers to cause a denial of service (ABEND) and possibly execute arbitrary code via (1) a long user name or (2) an unknown attack related to a "special script against login."

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.
