NVD · uneditedA vulnerability in the Cisco Jabber Guest Server could allow an unauthenticated, remote attacker to initiate connections to arbitrary hosts. More Information: CSCvc31635. Known Affected Releases: 10.6(9). Known Fixed Releases: 11.0(0).
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 confidenceThis is a Server-Side Request Forgery (SSRF) vulnerability in Cisco Jabber Guest Server. An unauthenticated, remote attacker can force the server to initiate outbound connections to arbitrary hosts, potentially enabling internal network reconnaissance, firewall bypass, and attacks against internal services.

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 Guest Server is installedCheck for Cisco Jabber Guest processes or installation directories on the system. Look for processes named 'JabberGuest' or installation paths like C:\Program Files\Cisco\JabberGuest or /opt/cisco/jabberguestAffected if The software is present on the system
-
Determine the installed version of Cisco Jabber GuestLocate the version information in the installation directory, registry (Windows), or by querying the service. Common locations: check version.txt in the installation folder, or look in Windows Registry under HKLM\Software\Cisco Systems\JabberGuestAffected if The installed version matches one of the affected versions: 10.0.0, 10.0.2, 10.5.0, 10.6.8, or 10.6.9
-
Verify the SSRF vulnerability is exploitableSince this is an unauthenticated SSRF, attempt to send a crafted request to the Cisco Jabber Guest web interface (typically ports 8080 or 8443) that triggers an outbound HTTP connection to an external host you control. Use a tool like Burp Suite or curl to test for arbitrary URL loading capability in the applicationAffected if The server can be forced to make outbound connections to arbitrary hosts without authentication
You are affected if Cisco Jabber Guest Server version 10.0.0, 10.0.2, 10.5.0, 10.6.8, or 10.6.9 is installed and the web interface accepts unauthenticated requests that trigger outbound connections.

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 Cisco Jabber Guest Server to version 11.0(0) or later. As a compensating control, restrict outbound network access from the Jabber Guest server using firewalls or ACLs to prevent abuse of the vulnerability.
