CVE-2021-1246
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 · uneditedCisco Finesse, Cisco Virtualized Voice Browser, and Cisco Unified CVP OpenSocial Gadget Editor Unauthenticated Access Vulnerability A vulnerability in the web management interface of Cisco Finesse, Cisco Virtualized Voice Browser, and Cisco Unified CVP could allow an unauthenticated, remote attacker to access the OpenSocial Gadget Editor without providing valid user credentials. The vulnerability is due to missing authentication for a specific section of the web-based management interface. An attacker could exploit this vulnerability by accessing a crafted URL. A successful exploit could allow the attacker to obtain access to a section of the interface, which they could use to obtain potentially confidential information and create arbitrary XML files. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
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 confidenceThis is an authentication bypass vulnerability in Cisco's web-based management interfaces for Finesse, Virtualized Voice Browser, and Unified CVP. The OpenSocial Gadget Editor lacks proper authentication checks, allowing unauthenticated remote attackers to access it via a crafted URL. Successful exploitation grants access to confidential information and the ability to create arbitrary XML files on the affected system.

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 Finesse installationAccess the Finesse web interface or check system inventory for Cisco Finesse presence. The product is typically accessed via https://<hostname>/finesseAffected if Cisco Finesse is installed and running
-
Check installed Finesse versionLog into the Finesse admin console and navigate to System > Version, or use the CLI command 'show version' on the Finesse serverAffected if The installed version is 12.0(1) or 12.5(1)
-
Verify OpenSocial Gadget Editor accessibilityAttempt to access the Gadget Editor directly via a crafted URL pattern such as https://<finesse-host>/gadgetContainer/gadgets/opensocial/editor/ or check if the endpoint responds without authenticationAffected if The Gadget Editor endpoint is reachable without requiring authentication credentials
-
Confirm web management interface exposureDetermine if the Finesse web management interface (port 443) is exposed to network or is accessible externallyAffected if The management interface is exposed to untrusted networks where attackers could send crafted requests
A user is affected if they are running Cisco Finesse versions 12.0(1) or 12.5(1) with the web-based management interface accessible and the OpenSocial Gadget Editor endpoint exposed without authentication.
