CVE-2018-13282
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 · uneditedSession fixation vulnerability in SYNO.PhotoStation.Auth in Synology Photo Station before 6.8.7-3481 allows remote attackers to hijack web sessions via the PHPSESSID 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 confidenceSession fixation vulnerability in Synology Photo Station's authentication module allows attackers to pre-set a known PHPSESSID cookie value before user authentication. Once the user logs in, the attacker can use that same session ID to hijack the authenticated session.

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 Photo Station versionAccess Synology DSM, open Package Center, find Photo Station, and note the installed version number. Alternatively, access Photo Station directly and check the version in Help > About.Affected if version is 6.3.x (before 6.3-2976) or 6.8.x (before 6.8.7-3481)
-
Verify PHP session configurationCheck the PHP configuration file (php.ini) for session.cookie_httponly and session.use_strict_mode settings. On Synology NAS, this is typically located at /etc/php or within the web station configuration.Affected if session.use_strict_mode is disabled (set to 0) or not present, allowing session fixation attacks
-
Test session ID handling before authenticationUsing a browser or HTTP tool, set a custom PHPSESSID cookie value (e.g., PHPSESSID=test123456) before logging in to Photo Station. Complete the login and check if the same session ID is retained.Affected if the PHPSESSID value set before authentication persists after successful login (session ID is not regenerated)
-
Inspect session handler behaviorExamine the PHP session save handler configuration and Photo Station's authentication code (if accessible via SSH to the NAS) for session_regenerate_id() calls during the login process.Affected if session_regenerate_id() is not called upon successful authentication
The environment is affected if Photo Station version falls within the vulnerable ranges AND session IDs are not regenerated after login, allowing an attacker who pre-sets a PHPSESSID to hijack authenticated sessions.

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 data6.3-29766.8.7-3481
Upgrade Synology Photo Station to version 6.8.7-3481 or later. As an interim control, consider forcing session ID regeneration upon authentication if patching is delayed.
