CVE-2024-20347
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 · uneditedA vulnerability in Cisco Emergency Responder could allow an unauthenticated, remote attacker to conduct a CSRF attack, which could allow the attacker to perform arbitrary actions on an affected device. This vulnerability is due to insufficient protections for the web UI of an affected system. An attacker could exploit this vulnerability by persuading a user to click a crafted link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the affected user, such as deleting users from the device.
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 confidenceCross-Site Request Forgery vulnerability in Cisco Emergency Responder web UI. An unauthenticated remote attacker can exploit insufficient CSRF protections by tricking an authenticated user into clicking a crafted link, allowing arbitrary actions (such as user deletion) with the victim's privilege level.

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.
-
Confirm Cisco Emergency Responder is installedLocate the Cisco Emergency Responder installation on the system or check if the service is running. On the server, look for the product directory or check running processes for CER-related services.Affected if The product is not present on the system.
-
Identify installed versionAccess the Cisco Emergency Responder command line interface and run the command to display the version, such as 'show version' or the administrative web UI version display. Note the exact version number displayed.Affected if The installed version matches any of these: < 12.5(1)su8b, = 14, = 14su1, = 14su2, = 14su3, = 14su3a
-
Verify web UI is accessibleConfirm the Cisco Emergency Responder web interface is reachable by accessing the admin URL (typically https://hostname/cer) from a browser or curl request. The CSRF vulnerability targets the web UI.Affected if The web UI is exposed and accessible to users.
-
Check for active authenticated sessionsReview active user sessions on the system or verify that users have active sessions in the web UI. CSRF attacks require an authenticated user session to be active when the malicious request is triggered.Affected if There are active authenticated sessions in the web UI.
The environment is affected if Cisco Emergency Responder is installed with a version matching the affected ranges AND the web UI is accessible to trigger CSRF attacks against authenticated users.

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 data12.5
Apply Cisco's patch when available; until then, educate users to avoid clicking untrusted links and consider using browser CSRF extensions as a temporary mitigation.
