CVE-2013-1187
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 Connection Manager in Cisco Jabber Extensible Communications Platform (aka Jabber XCP) does not properly validate login data, which allows remote attackers to cause a denial of service (service crash) by sending a series of malformed login packets, aka Bug ID CSCts76762.
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 · moderate confidenceThe Connection Manager in Cisco Jabber Extensible Communications Platform (Jabber XCP) fails to properly validate login data, allowing remote attackers to send malformed login packets that cause the service to crash, resulting in denial of service.

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 if Cisco Jabber XCP is installedCheck for Cisco Jabber XCP processes or installed software on the system. Look for process names like 'Jabber' or 'XCP' in running processes, or check installed programs for Cisco Jabber.Affected if The software is present on the system
-
Confirm the Connection Manager component is runningCheck for the Cisco Jabber XCP Connection Manager service or process. This is typically a service that handles client connections and authentication.Affected if The Connection Manager service is active and listening for connections
-
Check network exposure of the Connection ManagerIdentify which ports the Connection Manager is listening on (typically ports in the 5220-5229 range for XMPP, or as configured). Use netstat or similar tools to list listening ports and identify which are externally accessible.Affected if The Connection Manager is exposed to untrusted networks or the internet
-
Review service availability and crash logsCheck system and application logs for evidence of the Connection Manager service crashing, restarting unexpectedly, or logging authentication-related errors. Look for patterns around login/authentication events.Affected if The service has experienced unexplained crashes or restarts, particularly following login attempts
-
Identify the installed versionCheck the installed version of Cisco Jabber XCP if possible. Since all versions are affected, this confirms exposure rather than susceptibility.Affected if Any version of Cisco Jabber XCP is installed (all versions are affected)
The environment is affected if Cisco Jabber XCP Connection Manager is installed and accessible, since all versions of this product are vulnerable to denial of service via malformed login packets.

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 relevant Cisco patch for Bug ID CSCts76762. If unavailable, implement network-level mitigations such as rate limiting on login endpoints and blocking sources sending malformed packets.
