CVE-2014-0731
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 administration interface in Cisco Unified Communications Manager (Unified CM) 10.0(1) and earlier allows remote attackers to bypass authentication and read Java class files via a direct request, aka Bug ID CSCum46497.
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 confidenceAuthentication bypass in Cisco Unified CM admin interface allows unauthenticated remote attackers to directly request and read Java class files. This could expose sensitive information such as configuration details, credentials, or proprietary code logic embedded in the class files.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Cisco Unified CM versionLog into the Cisco Unified CM admin interface and navigate to Help > About, or use the CLI command 'show version' via SSH to the serverAffected if The installed version matches one of the following: <= 10.0(1), 3.3(5), 3.3(5)sr1, 3.3(5)sr2a, 4.1(3), 4.1(3)sr1, 4.1(3)sr2, 4.1(3)sr3, 4.1(3)sr4, 4.2, 4.2.1, or 4.2.2
-
Confirm admin interface is network accessibleDetermine if the Cisco Unified CM admin web interface (typically ports 443 or 8443) is reachable from networks outside the trusted management network segmentAffected if The admin interface is exposed to untrusted or external networks without firewall restrictions
-
Test for unauthenticated Java class file accessUsing a web browser or curl, attempt to directly access a Java class file path such as '/ccmadmin/*.jsp' or common Java class file URLs without providing admin credentialsAffected if HTTP requests to Java class file paths return successful responses (200 OK) without requiring authentication
-
Review web server configurationCheck the Cisco Unified CM web server configuration files or HTTP access logs for requests to .class file extensions that were served without authenticationAffected if Access logs show .class file requests that were served to unauthenticated or unknown sessions
You are affected if your Cisco Unified Communications Manager version is in the affected list AND the admin interface is accessible from untrusted networks, allowing unauthenticated access to Java class files.

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 vendor patch from Cisco for Unified CM 10.0(1) and earlier. Until patched, restrict network access to the admin interface to trusted management networks only.
