CVE-2022-20802
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 interface of Cisco Enterprise Chat and Email (ECE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability is due to insufficient validation of user-supplied input that is processed by the web interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected system. A successful exploit could allow the attacker to execute arbitrary code in the context of the interface or access sensitive, browser-based information. To successfully exploit this vulnerability, an attacker would need valid agent 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 · moderate confidenceCisco Enterprise Chat and Email (ECE) web interface fails to properly validate user-supplied input, allowing authenticated attackers with valid agent credentials to inject malicious scripts via crafted HTTP requests. Successful exploitation enables arbitrary code execution in the context of the interface or theft of sensitive browser-based information.

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 ECE versionLocate the Cisco Enterprise Chat and Email installation directory and check the version file or use the product's admin interface to view version information. Typical locations include the application server's version info page or system information panel in the administration console.Affected if The installed version is lower than 12.6(1)es2 and the web interface is accessible
-
Verify web interface is enabledCheck the Cisco ECE configuration to confirm the web interface service is running and accessible. This can be done via the administration console status page or by reviewing the service configuration files.Affected if The web interface is exposed and accessible to users
-
Confirm agent authentication is configuredCheck the Cisco ECE system configuration to determine whether agent accounts are enabled and users can authenticate to the web interface. Review the authentication settings in the admin console.Affected if Agent credentials can be created or are already provisioned for web interface access
-
Compare version against affected rangeDocument the exact installed version number from step 1 and compare it against the affected range of versions prior to 12.6(1)es2.Affected if The version is below 12.6(1)es2 and the conditions from steps 2 and 3 are true
The environment is affected if Cisco Enterprise Chat and Email is installed with a version prior to 12.6(1)es2, the web interface is enabled, and agent accounts can authenticate to it.

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 · scoped12.6
Implement proper input validation and output encoding for all user-supplied data in the web interface, or apply Cisco's available security patch if released. Consider implementing Content Security Policy (CSP) headers as a defense-in-depth measure.
12.6(1)es2
- Verify current version of Cisco Enterprise Chat and Email by accessing the administration interface or running the appropriate version check command
- Download Cisco Enterprise Chat and Email version 12.6(1)es2 from the Cisco software downloads page (requires valid Cisco service contract)
- Review Cisco upgrade documentation for ECE 12.6(1)es2, including prerequisite checks and backup procedures
- Perform a complete backup of the ECE database, configuration files, and customizations
- In a non-production environment, perform the upgrade to 12.6(1)es2 and verify all core functionalities work (agent login, chat handling, email processing)
- Schedule a maintenance window and apply the upgrade to the production environment
- After upgrade, verify the XSS vulnerability is remediated by confirming user-supplied input in web interface is properly sanitized
- Log in as an agent and verify normal operations resume
