CVE-2023-29714
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 · uneditedCross Site Scripting vulnerability found in Vade Secure Gateway allows a remote attacker to execute arbitrary code via the username, password, and language cookies parameter.
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 confidenceCross-site scripting (XSS) vulnerability in Vade Secure Gateway allows remote attackers to inject arbitrary JavaScript code through malicious values in the username, password, and language cookies. When these cookie values are reflected in web pages without proper sanitization, the attacker's script executes in victims' browsers.

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 Vade Secure Gateway installation and versionLocate the Vade Secure Gateway installation and identify its version number. Check the application web interface, installation logs, or system package information. Compare the installed version against the affected range: version 3.0 and below.Affected if The installed version is 3.0 or lower
-
Verify web interface is accessibleAttempt to reach the Vade Secure Gateway login page or web portal over HTTP or HTTPS. This vulnerability requires the web application to be accessible for cookie injection to occur.Affected if The web interface is accessible to users or attackers on the network
-
Inspect cookie attributes for username, password, and language cookiesLog into the web interface or trigger the relevant authentication flows, then use browser developer tools or a proxy to examine the Set-Cookie headers and stored cookies. Check whether the username, password, and language cookies have the HttpOnly and Secure flags set.Affected if These cookies lack the HttpOnly flag, allowing JavaScript access, or lack the Secure flag when HTTPS is used
-
Review application response headers for Content Security PolicyCapture HTTP responses from the web application using a browser or HTTP client. Inspect the response headers for the presence of Content-Security-Policy or X-Content-Security-Policy headers.Affected if No CSP headers are present, or the policy does not restrict inline script execution
A defender is affected if Vade Secure Gateway version 3.0 or lower is running with its web interface accessible and the affected cookies (username, password, language) are set without HttpOnly/Secure flags or adequate CSP protection.
Generated from the published advisory. Verify against your own configuration.
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 dataImplement strict input validation and output encoding for all cookie parameters (username, password, language). Additionally, set HttpOnly and Secure flags on sensitive cookies and deploy Content Security Policy (CSP) headers to mitigate XSS execution.
