CVE-2018-8925
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 request forgery (CSRF) vulnerability in admin/user.php in Synology Photo Station before 6.8.5-3471 and before 6.3-2975 allows remote attackers to hijack the authentication of administrators via the (1) username, (2) password, (3) admin, (4) action, (5) uid, or (6) modify_admin 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 · high confidenceCross-site request forgery (CSRF) vulnerability in Synology Photo Station's admin/user.php endpoint allows remote attackers to hijack administrator authentication by tricking logged-in admins into submitting malicious requests that modify user credentials or perform administrative actions via parameters including username, password, admin, action, uid, and modify_admin.

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 Synology Photo Station is installedAccess your Synology DSM interface and check the Package Center for installed packages. Look for Photo Station in the installed list.Affected if Photo Station is not installed on the Synology device
-
Determine the installed Photo Station versionIn DSM Package Center, click on Photo Station and view the version information. Alternatively, access Photo Station directly and check the About or Settings page for the version number.Affected if The version cannot be determined or is not visible
-
Compare your version to affected rangesCompare the installed version against: 6.3-2944 through 6.3-2974 (or 6.3-2975 and later is fixed), and 6.8.0-3456 through 6.8.5-3470 (or 6.8.5-3471 and later is fixed).Affected if Installed version falls within 6.3-2944 to 6.3-2974 OR 6.8.0-3456 to 6.8.5-3470
-
Verify the admin/user.php endpoint existsAttempt to access the Photo Station admin interface at path /photo/admin/user.php on your Synology server (via local network IP or hostname).Affected if The endpoint responds and is accessible without authentication barriers preventing access to the admin functions
You are affected if Photo Station is installed and the installed version falls within the affected ranges (6.3-2944 to 6.3-2974 or 6.8.0-3456 to 6.8.5-3470), as the admin/user.php endpoint will be vulnerable to CSRF attacks.

From vendor data6.3-29756.8.5-3471
Apply vendor patches (upgrade to Photo Station 6.8.5-3471 or 6.3-2975 and later). Until patched, implement anti-CSRF tokens in all admin forms, enable SameSite cookie attributes, and validate HTTP referrer headers.
