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".
Cross-site scripting (XSS) vulnerability in PixlrEditorHandler.php in Synology Photo Station before 6.7.0-3414 allows remote attackers to inject arbitrary web script or HTML via the image parameter.
