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 · unedited
The Java Servlet framework on Cisco TelePresence Recording Server devices with software 1.6.x before 1.6.2 and Cisco TelePresence Multipoint Switch (CTMS) devices with software 1.0.x, 1.1.x, 1.5.x, and 1.6.x does not require administrative authentication for unspecified actions, which allows remote attackers to execute arbitrary code via a crafted request, aka Bug IDs CSCtf42005 and CSCtf42008.

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 confidence

CVE-2011-0383 is an authentication bypass vulnerability in the Java Servlet framework on Cisco TelePresence Recording Server (versions 1.6.x before 1.6.2) and Cisco TelePresence Multipoint Switch (versions 1.0.x, 1.1.x, 1.5.x, and 1.6.x). The framework fails to require administrative authentication for certain actions, allowing remote unauthenticated attackers to execute arbitrary code via crafted HTTP requests.

MitigationApply vendor-supplied firmware/software updates to upgrade TelePresence Recording Server to version 1.6.2 or later and CTMS to the latest available patched version; if no update path exists, network segmentation and restricting management interfaces to authorized networks may reduce exposure.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed TelePresence products
    Review your environment for Cisco TelePresence Recording Server (CTRS) or Cisco TelePresence Multipoint Switch (CTMS) installations. Check for associated processes, services, or known hostnames/IPs dedicated to these devices.
    Affected if Either product is present in the environment
  2. Determine CTRS version
    Access the Recording Server administrative interface or CLI and locate the software version information. Typical paths: web UI 'System > About' page, or CLI command 'show version' or 'show system' depending on the interface available.
    Affected if Version is 1.6.x before 1.6.2, or any 1.6.1 version, or any version labeled only as '1.6.x' without a specific minor release
  3. Determine CTMS version
    Access the Multipoint Switch administrative interface or CLI and locate the software version information. Typical paths: web UI 'System > About' page, or CLI command 'show version' or 'show system'.
    Affected if Version matches exactly 1.0.4.0, 1.1.0, 1.1.1, 1.1.2, 1.5.0, 1.5.1, 1.5.2, 1.5.3, 1.5.4, 1.5.5, 1.5.6, or 1.6.0; or the product is present with any version designation from the 1.0.x, 1.1.x, 1.5.x, or 1.6.x release trains
  4. Confirm Java Servlet framework is in use
    Verify that the affected device exposes HTTP/HTTPS management interfaces. This vulnerability targets the Java Servlet framework component of these products, which handles web-based administrative functions.
    Affected if HTTP or HTTPS management interfaces are enabled and accessible on the TelePresence device
  5. Assess network exposure of management interface
    Review firewall rules, ACLs, or network segmentation to determine if the HTTP/HTTPS management ports (commonly 80, 443, or custom ports) are reachable from untrusted networks or the internet.
    Affected if Management interface is reachable from networks outside the trusted administrative zone

You are affected if Cisco TelePresence Recording Server version 1.6.x before 1.6.2 (or version 1.6.1 specifically) or Cisco TelePresence Multipoint Switch version 1.0.4.0, 1.1.x, 1.5.x, or 1.6.0 is installed and its HTTP-based management interface is network-accessible.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply vendor-supplied firmware/software updates to upgrade TelePresence Recording Server to version 1.6.2 or later and CTMS to the latest available patched version; if no update path exists, network segmentation and restricting management interfaces to authorized networks may reduce exposure.

Recommended fix Moderate confidence

Cisco TelePresence Recording Server: version 1.6.2 or later; Cisco TelePresence Multipoint Switch: contact Cisco for fixed release

  1. 1. Identify the exact version of Cisco TelePresence Recording Server or Multipoint Switch currently installed
  2. 2. For TelePresence Recording Server: Upgrade to version 1.6.2 or later
  3. 3. For TelePresence Multipoint Switch: Contact Cisco for the specific fixed release as the description indicates 1.0.x, 1.1.x, 1.5.x, and 1.6.x are affected but does not specify the fixed version
  4. 4. After upgrade, verify that administrative authentication is now required for all sensitive actions
  5. 5. Review system logs to check for any prior unauthorized access attempts
