CVE-2011-1623
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 · uneditedCisco Media Processing Software before 1.2 on Media Experience Engine (MXE) 5600 devices has a default root password, which makes it easier for context-dependent attackers to obtain access via (1) the local console, (2) an SSH session, or (3) a TELNET session, aka Bug ID CSCto77737.
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 confidenceCisco Media Processing Software before version 1.2 on Media Experience Engine (MXE) 5600 devices ships with a default root password that is publicly known. Attackers with network access via SSH, TELNET, or physical access via console can authenticate using these default credentials to gain full root privileges on the device.

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.
-
Check Cisco Media Processing Software versionAccess the device management interface or run 'show version' via console/SSH and identify the installed Cisco Media Processing Software version numberAffected if The installed version is 1.0.0, 1.0.1, 1.1.0, 1.1.1, or any version 1.1.3 or lower (versions prior to 1.2)
-
Confirm Cisco MXE 5600 modelVerify the device model via 'show hardware' or physical label inspection to confirm it is a Cisco Media Experience Engine 5600Affected if The device is a Cisco MXE 5600 (all versions are affected per vendor advisory)
-
Verify root password has been changedLog into the device as root (via console, SSH, or TELNET) and confirm the password has been changed from the publicly known default credential; if you do not know the original default, contact Cisco TAC for the default credentials and compareAffected if The root password remains at the default value (publicly known from CVE-2011-1623 disclosure)
-
Check for exposed management servicesReview device configuration or run 'show ip interface' to determine if SSH, TELNET, or console access are enabled and accessible over networkAffected if SSH, TELNET, or console access is enabled and reachable from untrusted networks
You are affected if the device is a Cisco MXE 5600 running any version of Cisco Media Processing Software prior to 1.2 AND the root password has not been changed from the default value.

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.
dbcve · scopedChange the default root password immediately to a strong, unique credential and update to Cisco Media Processing Software version 1.2 or later. Consider disabling TELNET in favor of SSH and restricting physical and network access to management interfaces.
Cisco Media Processing Software 1.2 or later
- Download Cisco Media Processing Software version 1.2 or later from the Cisco website
- Verify the integrity of the downloaded image using Cisco's published checksums
- Schedule a maintenance window for the upgrade
- Back up current configuration following Cisco best practices
- Upgrade the Media Processing Software on the Media Experience Engine (MXE) 5600
- After upgrade, change the default root password immediately using the 'passwd' command
- Verify SSH and TELNET access works with the new credentials
- Confirm the upgrade was successful and the vulnerability is resolved
