CVE-2012-0402
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 · uneditedEMC RSA enVision 4.x before 4.1 Patch 4 uses unspecified hardcoded credentials, which makes it easier for remote attackers to obtain access via unknown vectors.
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 confidenceEMC RSA enVision versions 4.x prior to 4.1 Patch 4 contain undocumented hardcoded credentials embedded in the software firmware. These credentials allow remote unauthenticated attackers to gain unauthorized administrative access to the enVision platform, potentially exposing all collected security event data and system functionality.

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 RSA enVision versionAccess the enVision administrative interface or check system information to determine the running software version. This is typically found in the About or System Status section of the admin panel.Affected if The version displayed is 4.0 or 4.1 (prior to Patch 4)
-
Confirm version is within vulnerable rangeCompare the identified version against the affected ranges: version 4.0 or version 4.1 without Patch 4 applied.Affected if The version is exactly 4.0 or 4.1 without having applied Patch 4
-
Assess network exposure of the enVision systemDetermine if the enVision management interface is accessible from network segments outside the trusted internal network, as this is a remote unauthenticated vulnerability.Affected if The enVision interface is reachable from untrusted networks or the internet without proper access controls
A system is affected if it runs RSA enVision version 4.0 or version 4.1 without Patch 4 applied and has network accessibility, because these versions contain undocumented hardcoded credentials that allow remote administrative access.

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 EMC RSA enVision 4.1 Patch 4 or later to remove the hardcoded credentials. After patching, change all default credentials, review access logs for unauthorized administrative access, and implement network segmentation to limit exposure of the enVision system.
