A design flaw in authentication in Synology Photo Station 6.0-2528 through 6.7.1-3419 allows local users to obtain credentials via cmdline. Synology Photo Station employs the synophotodsmuser program to authenticate username and password by "synophotodsmuser --auth USERNAME PASSWORD", and local users are able to obtain credentials by sniffing "/proc//cmdline".

Multiple cross-site scripting (XSS) vulnerabilities in Synology Photo Station 6.0 before 6.0-2638 and 6.3 before 6.3-2962 allow remote authenticated attackers to inject arbitrary web script or HTML via the (1) album name, (2) file name of uploaded photos, (3) description of photos, or (4) tag of the photos.
