CVE-2008-7300
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe labeled networking implementation in Solaris Trusted Extensions in Sun Solaris 10 and OpenSolaris snv_39 through snv_67, when a labeled zone is in the installed state, allows remote authenticated users to bypass a Mandatory Access Control (MAC) policy and obtain access to the global zone.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis vulnerability in Solaris Trusted Extensions labeled networking allows remote authenticated users to bypass Mandatory Access Control (MAC) policies and gain unauthorized access to the global zone when a labeled zone is in the installed (non-running) state. The flaw exists in the MAC enforcement logic that should prevent communication between labeled zones and the global zone.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the Solaris version and buildRun 'uname -a' or 'cat /etc/release' to determine the exact Solaris version and build number. Compare against SunOS 5.10 (Solaris 10) and OpenSolaris builds snv_39, snv_47, snv_59, snv_64, or snv_67.Affected if The system is running Solaris 10 (SunOS 5.10) or one of the listed OpenSolaris build numbers.
-
Confirm Trusted Extensions is enabledCheck if Trusted Extensions is installed and active. This can be verified by examining the system's security configuration or running 'txzonemgr' if available, or by checking if the Trusted Extensions services are running.Affected if Trusted Extensions is enabled on the system.
-
Identify labeled zones and their stateUse the zone management utility (such as 'zoneadm list -iv') to list all zones and their current state. Look specifically for zones with labels that are in the 'installed' state but not currently running.Affected if There exists at least one labeled zone in the 'installed' (non-running) state on the system.
-
Verify network configuration between zonesExamine the network configuration to determine if labeled zones are configured with network connectivity that could allow communication to the global zone. Check the MAC enforcement policy settings for inter-zone communication.Affected if Labeled zones have network configuration that permits potential communication with the global zone while in the installed state.
A system is affected if it runs Solaris 10 or one of the specific OpenSolaris builds, has Trusted Extensions enabled, and contains a labeled zone in the installed (non-running) state with network access configured.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the relevant Oracle/Sun patches for CVE-2008-7300 to affected Solaris 10 and OpenSolaris systems. If patches are unavailable, consider disabling unused labeled zones or upgrading to a supported Solaris version.
