CVE-2023-23849
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 · uneditedVersions of Coverity Connect prior to 2022.12.0 are vulnerable to an unauthenticated Cross-Site Scripting vulnerability. Any web service hosted on the same sub domain can set a cookie for the whole subdomain which can be used to bypass other mitigations in place for malicious purposes.

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 · high confidenceCoverity Connect versions prior to 2022.12.0 contain an unauthenticated cross-site scripting (XSS) vulnerability where any web service hosted on the same subdomain can set cookies for the entire subdomain, enabling bypass of existing security mitigations for malicious purposes.

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.
-
Determine the installed Coverity Connect versionAccess the Coverity Connect administration interface or check the installation metadata (commonly found in version files, about pages, or the installation directory). Compare the version number to the 2022.12.0 release.Affected if The installed version is any release prior to 2022.12.0 (e.g., 2022.9.0, 2022.6.0, etc.)
-
Identify all web services hosted on the same subdomain as Coverity ConnectReview the DNS records and web server configurations to enumerate all applications and services accessible within the same subdomain namespace (e.g., coverity.example.com, otherapp.example.com).Affected if Any additional web services exist on the same subdomain as the Coverity Connect instance
-
Verify cookie security configuration for the subdomainInspect the HTTP response headers from the Coverity Connect server, specifically looking for Set-Cookie directives and their attributes (Secure, HttpOnly, SameSite). Also check if the domain attribute is set to a broad subdomain.Affected if Cookies are set with a broad subdomain domain attribute or lack appropriate SameSite and Secure flags, allowing other services on the subdomain to influence them
-
Check for unauthenticated access to web service endpointsAttempt to access Coverity Connect web interfaces without authentication credentials. Review access logs for unauthenticated requests to API or web endpoints.Affected if The Coverity Connect web interface accepts requests without requiring authentication, enabling the XSS attack vector
A system is affected if it runs any version of Coverity Connect prior to 2022.12.0 and has other web services or unprotected endpoints on the same subdomain, allowing cookie manipulation for XSS exploitation.
