CVE-2022-20658
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 the web-based management interface of Cisco Unified Contact Center Management Portal (Unified CCMP) and Cisco Unified Contact Center Domain Manager (Unified CCDM) could allow an authenticated, remote attacker to elevate their privileges to Administrator. This vulnerability is due to the lack of server-side validation of user permissions. An attacker could exploit this vulnerability by submitting a crafted HTTP request to a vulnerable system. A successful exploit could allow the attacker to create Administrator accounts. With these accounts, the attacker could access and modify telephony and user resources across all the Unified platforms that are associated to the vulnerable Cisco Unified CCMP. To successfully exploit this vulnerability, an attacker would need valid Advanced User credentials.
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 confidenceA privilege escalation vulnerability in Cisco Unified CCMP and Unified CCDM web management interface allows authenticated Advanced Users to create Administrator accounts via crafted HTTP requests due to missing server-side permission validation. This grants full administrative access to telephony and user resources across integrated Unified platforms.

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 installed Cisco Unified Contact Center product versionAccess the web management interface and navigate to the About or System Information page to view the exact version number. Alternatively, use the CLI command 'show version' or 'utils system version' if you have shell access.Affected if The installed version is 12.0.1, 12.5.1, or any version 11.6.1 or earlier of Unified Contact Center Management Portal.
-
Determine if web management interface is accessibleVerify network accessibility to the web management interface port (typically HTTPS port 443) from untrusted networks. Check firewall rules and access control lists.Affected if The management interface is reachable from networks outside the trusted administrative zone.
-
Review administrator accounts for unauthorized creationsLog into the web management interface as an administrator and navigate to the User Administration or Account Management section. Export the list of administrator accounts and review the 'created by' or 'creator' field for each account.Affected if There are administrator accounts that were created by users who do not hold Administrator-level privileges, or there are unexpected administrator accounts.
-
Audit web server logs for privilege escalation attemptsExamine web server access logs (typically found in /var/log/httpd or platform-specific log directories) for POST requests to account creation endpoints, particularly those targeting administrative role assignment.Affected if Logs contain account creation requests with elevated role parameters originating from Advanced User sessions.
You are affected if your installed version matches 12.0.1, 12.5.1, or <= 11.6.1 AND the web management interface is accessible, with potential indicator being unauthorized administrator accounts created by non-admin 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 dataApply Cisco's security patches for this vulnerability. Ensure network access to the management interface is restricted to trusted users and monitor for unauthorized administrator account creation.
