CVE-2011-0756
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 application server in Trustwave WebDefend Enterprise before 5.0 uses hardcoded console credentials, which makes it easier for remote attackers to read security-event data by using the remote console GUI to connect to the management port.
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 · high confidenceThe application server in Trustwave WebDefend Enterprise before version 5.0 contains hardcoded console credentials embedded in the code or configuration. Remote attackers can use these credentials to connect to the management port via the remote console GUI and access sensitive security-event data without proper authentication.

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 installed WebDefend versionLocate and inspect the WebDefend installation directory or check the software version through the system registry, installed programs list, or running services associated with Trustwave WebDefend Enterprise.Affected if The installed version is WebDefend Enterprise 3.0 or earlier, or specifically version 2.0.
-
Confirm management port accessibilityIdentify which port the WebDefend management console runs on (typically a listener service) and test remote connectivity to that port from an untrusted network perspective using tools like netstat, nmap, or port scanning.Affected if The management port is accessible from network segments that are not fully trusted or from external networks.
-
Inspect configuration files for embedded credentialsExamine the WebDefend configuration files, particularly those in the conf or config directories within the installation path, for hardcoded username and password strings that may appear as default or embedded credentials.Affected if Configuration files contain hardcoded credentials such as default usernames and passwords that were not set by the administrator.
-
Review remote console access logsCheck WebDefend audit or access logs for remote console connections originating from IP addresses that should not have legitimate access, or for successful authentications using default or administrative credentials.Affected if Logs show remote console connections from unexpected sources or authentications using default administrative accounts.
You are affected if WebDefend Enterprise version 3.0 or earlier (including version 2.0) is installed and its management port is accessible, with hardcoded credentials present in the configuration.

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 dataUpgrade to WebDefend Enterprise 5.0 or later to obtain patched software without hardcoded credentials. If immediate upgrade is not feasible, implement network segmentation to restrict access to the management port and add additional authentication layers.
