CVE-2022-20634
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 ECE could allow an unauthenticated, remote attacker to redirect a user to an undesired web page. This vulnerability is due to improper input validation of the URL parameters in an HTTP request that is sent to an affected system. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to cause the interface to redirect the user to a specific, malicious URL. This type of vulnerability is known as an open redirect and is used in phishing attacks that get users to unknowingly visit malicious sites.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

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 if Cisco Enterprise Chat and Email is deployedCheck your inventory or running services for Cisco ECE web-based management interface. Look for processes named 'Cisco ECE', 'Enterprise Chat and Email', or check for ports commonly used by web interfaces (typically 443 or 8080).Affected if Cisco ECE web-based management interface is present in the environment
-
Locate the installed version of Cisco ECEAccess the web-based management interface and navigate to the About or System Information page, typically found under Admin or Help sections. Alternatively, check installation directories or version files if you have server access.Affected if The version displayed is below 12.6(1)es1
-
Compare your version against the affected rangeDocument the exact version number found and compare it numerically to 12.6(1)es1. Any version lower than 12.6(1)es1 is affected.Affected if Installed version is < 12.6(1)es1
-
Verify the management interface is network-accessibleConfirm the web-based management interface is reachable from network locations. Check if it is exposed externally or internally via browser access to the management URL.Affected if The interface is accessible and the installed version is below 12.6(1)es1
You are affected if Cisco Enterprise Chat and Email is running with a web-based management interface version lower than 12.6(1)es1.
