CVE-2020-3193
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 Prime Collaboration Provisioning could allow an unauthenticated, remote attacker to obtain sensitive information about an affected device. The vulnerability exists because replies from the web-based management interface include unnecessary server information. An attacker could exploit this vulnerability by inspecting replies received from the web-based management interface. A successful exploit could allow the attacker to obtain details about the operating system, including the web server version that is running on the device, which could be used to perform further attacks.
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 confidenceThe web-based management interface of Cisco Prime Collaboration Provisioning returns unnecessary server information (OS details, web server version) in HTTP responses. An unauthenticated remote attacker can inspect these responses to gather reconnaissance information about the system, which could aid in planning further attacks.

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 Prime Collaboration Provisioning is runningIdentify if the web-based management interface is accessible by making an HTTP/HTTPS request to the hostname or IP where it is hosted. Look for login pages or error messages referencing 'Cisco Prime Collaboration Provisioning' or 'cpvp' in the response.Affected if The web interface is accessible and identifies as Cisco Prime Collaboration Provisioning.
-
Check the installed versionLocate the installed version of Cisco Prime Collaboration Provisioning by accessing the application's 'About' page, checking the release notes included with the installation, or querying the application through its administrative interface or API for the version number.Affected if The version is less than 12.6 or exactly equals 12.6.
-
Inspect HTTP response headers for information disclosureSend an HTTP GET request to the web interface (such as to the root URL or common endpoints like /cpvp/ or /login) and capture the full response headers using a tool like curl with the -I flag or a network proxy. Examine headers such as Server, X-Powered-By, and any custom headers for OS details, web server version numbers, or platform information.Affected if Response headers contain OS details, specific web server version numbers, or other reconnaissance-revealing information beyond basic server identification.
-
Inspect HTTP response body for information disclosureSend an HTTP GET request to the web interface and examine the HTML body for version strings, error pages, or debug output that reveals OS details, installed component versions, or system paths.Affected if The response body displays OS information, detailed version numbers, or system configuration details not necessary for normal operation.
A user is affected if Cisco Prime Collaboration Provisioning version 12.6 or earlier is running and HTTP responses from the web interface expose OS details, web server version, or other system information in headers or body.

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 data12.6
Apply vendor patches when available; until then, consider implementing web server configuration changes to suppress server banners and employ WAF rules to filter sensitive HTTP headers.
