CVE-2023-20069
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 Infrastructure and Cisco Evolved Programmable Network (EPN) Manager could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface on an affected device. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker would need to have valid credentials to access the web-based management interface of the affected 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 · moderate confidenceThis is a stored cross-site scripting (XSS) vulnerability in Cisco Prime Infrastructure and Cisco EPN Manager web-based management interfaces. An authenticated attacker can inject malicious script through insufficiently validated user input that persists on the server, executing in the browser context of other users viewing the affected content.

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 management productDetermine if Cisco Prime Infrastructure or Cisco Evolved Programmable Network Manager (EPN Manager) is installed on the system. Check installed applications, services, or documentation for the product name.Affected if Neither product is installed, then this CVE does not apply.
-
Check product versionLocate the installed version of the Cisco management product. For Prime Infrastructure, this is typically shown in the web UI login page or in the Administration > Settings > Software Update section. For EPN Manager, check the About page or the /opt/epnm/version file if accessible.Affected if Version is less than 3.10.3 for Prime Infrastructure, or less than 7.0 for EPN Manager.
-
Verify web-based management interface is enabledConfirm that the web-based management interface is accessible and operational. Attempt to reach the login page of the management interface over HTTPS (default ports 443 or 8443).Affected if The web interface is disabled or not accessible, the XSS attack surface is not present.
-
Confirm authentication is required for the interfaceVerify that the web management interface requires authentication to access. Ensure that no anonymous or unauthenticated access paths exist that would allow bypassing login.Affected if The interface is exposed without authentication, the specific authenticated attack vector described in this CVE would not apply in the expected manner.
The environment is affected if either Cisco Prime Infrastructure < 3.10.0 or Cisco EPN Manager < 7.0 is installed with the web management interface enabled and accessible.

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.
dbcve · scoped3.10.37.0
Apply Cisco security patches when available. In the interim, implement output encoding and input validation on all user-supplied fields. Restrict user privileges and monitor for suspicious administrative activity.
Cisco Prime Infrastructure 3.10.3+ or Cisco Evolved Programmable Network Manager 7.0+
- 1. Back up the current configuration and data of the affected device before initiating any upgrade.
- 2. Download the fixed release from Cisco - for Prime Infrastructure use version 3.10.3 or later, for Evolved Programmable Network Manager use version 7.0 or later.
- 3. Verify the integrity of the downloaded image using the checksum provided by Cisco.
- 4. Schedule a maintenance window as upgrades require downtime.
- 5. Follow Cisco's official upgrade documentation for your specific product to apply the upgrade.
- 6. After upgrade, verify the new version is running: Prime Infrastructure should show 3.10.3 or higher; EPN Manager should show 7.0 or higher.
- 7. Log in to the web interface and confirm the vulnerability is remediated by checking that user input is properly sanitized.
