A flaw was found in the bash functionality that evaluates specially formatted environment variables passed to it from another environment. An attacker could use this feature to override or bypass restrictions to the environment to execute shell commands before restrictions have been applied. Certain services and applications allow remote unauthenticated attackers to provide environment variables, allowing them to exploit this issue.

GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the modcgi and modcgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.

The ZCC page in Novell ZENworks Configuration Management (ZCM) before 11.2.4 allows attackers to conduct cross-frame scripting attacks via unknown vectors.

Session fixation vulnerability in Novell ZENworks Configuration Management (ZCM) before 11.2.4 allows remote attackers to hijack web sessions via unspecified vectors.

Cross-site request forgery (CSRF) vulnerability in the ZCC page in Novell ZENworks Configuration Management (ZCM) before 11.2.4 allows remote attackers to hijack the authentication of unspecified victims via unknown vectors.

Unspecified vulnerability in the ZCC page in Novell ZENworks Configuration Management (ZCM) before 11.2.4 has unknown impact and attack vectors related to an "Application Exception."

The ISList.ISAvi ActiveX control in AdminStudio in Novell ZENworks Configuration Management (ZCM) 10.2, 10.3, and 11 SP1 provides access to the mscomct2.ocx file, which allows remote attackers to execute arbitrary code by leveraging unspecified mscomct2 flaws.

Buffer overflow in the DoFindReplace function in the ISGrid.Grid2.1 ActiveX control in InstallShield/ISGrid2.dll in AdminStudio in Novell ZENworks Configuration Management (ZCM) 10.2, 10.3, and 11 SP1 allows remote attackers to execute arbitrary code via a long bstrReplaceText parameter.

Directory traversal vulnerability in the LaunchProcess function in the LaunchHelp.HelpLauncher.1 ActiveX control in LaunchHelp.dll in AdminStudio in Novell ZENworks Configuration Management (ZCM) 10.2, 10.3, and 11 SP1 allows remote attackers to execute arbitrary commands via a pathname in the first argument.

Directory traversal vulnerability in the ISCreateObject method in an ActiveX control in InstallShield\ISProxy.dll in AdminStudio in Novell ZENworks Configuration Management (ZCM) 10.3 through 11.2 allows remote attackers to execute arbitrary local DLL files via a crafted web page that also calls the Initialize method.

Directory traversal vulnerability in an unspecified servlet in the Inventory component in ZENworks Asset Management (ZAM) in Novell ZENworks Configuration Management 10.3 before 10.3.2, and 11, allows remote attackers to overwrite files, and subsequently execute arbitrary code, via directory traversal sequences in a filename field in an upload request.

The web server in Novell ZENworks Configuration Management (ZCM) 10.3 and 11.2 before 11.2.4 does not properly perform authentication for zenworks/jsp/index.jsp, which allows remote attackers to conduct directory traversal attacks, and consequently upload and execute arbitrary programs, via a request to TCP port 443.
