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 Emergency Responder installationCheck for Cisco Emergency Responder processes or installed files on the system. Common installation paths may include /opt/cisco/cer or similar directories. Use commands like 'ps -ef | grep -i cer' or 'ls -la /opt/' to locate the application.Affected if Cisco Emergency Responder is installed on the system
-
Verify Cisco Emergency Responder versionLocate the version file or use CLI commands. Check /opt/ciscer/release or look for version information in the web interface login page. Compare the installed version to 11.5(0.99833.5).Affected if The installed version matches 11.5(0.99833.5) or falls within uncertain version ranges near this release
-
Confirm web interface accessibilityAttempt to access the Cisco Emergency Responder web interface via browser or curl at common ports such as 8443 or 443. Check if the application responds to HTTP/HTTPS requests.Affected if The web interface is accessible and responds to requests
-
Check for Sun Opensolaris presenceVerify the operating system version using 'uname -a' or 'cat /etc/release' to identify if Sun Opensolaris snv_124 is running.Affected if The system is running Sun Opensolaris snv_124
A user is affected if Cisco Emergency Responder version 11.5(0.99833.5) is installed with an accessible web interface, or if the system runs Sun Opensolaris snv_124, as both configurations allow remote unauthenticated XSS attacks via the application.
