CVE-2025-49189
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 · uneditedThe HttpOnlyflag of the session cookie \"@@\" is set to false. Since this flag helps preventing access to cookies via client-side scripts, setting the flag to false can lead to a higher possibility of Cross-Side-Scripting attacks which target the stored cookies.
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 confidenceThe session cookie '@@' has its HttpOnly flag set to false, allowing client-side JavaScript to access the cookie contents. This enables XSS attacks to steal session cookies, potentially compromising user accounts.

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 Sick Media Server is installedLocate the Sick Media Server installation directory or check for running processes/service named 'sick-media-server' or similarAffected if The product is not installed, this CVE does not apply
-
Check installed versionRun: sick-media-server --version or check the version file in the installation directoryAffected if Version is less than 1.5 - the vulnerability is present in versions below this
-
Identify session cookie configurationLocate the configuration file where cookies are defined (commonly in config, settings, or session management files within the application directory)Affected if No cookie configuration file exists - cannot verify the HttpOnly status
-
Inspect HttpOnly flag for '@@' cookieOpen the cookie configuration file and search for a cookie named '@@'. Check if the HttpOnly attribute is set to false or is missing/trueAffected if The '@@' cookie exists and HttpOnly is set to false, or the HttpOnly attribute is absent entirely
If Sick Media Server version is below 1.5 AND the '@@' session cookie exists with HttpOnly set to false or not set, the environment is affected by this CVE.
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.
dbcve · scoped1.5
Set the HttpOnly attribute to 'true' on the session cookie '@@' in the application's cookie configuration to prevent client-side script access.
Media Server version 1.5
- Create a backup of the current Media Server configuration and data
- Download Media Server version 1.5 from the official SICK website (sick.com)
- Stop the Media Server service
- Install Media Server version 1.5
- Verify that the HttpOnly flag is now properly set on the session cookie by examining cookie headers in HTTP responses
- Start the Media Server service
