Seagate Personal Cloud is a consumer-grade Network-Attached Storage device (NAS). It was found that the web application used to manage the NAS is affected by various unauthenticated information disclosure vulnerabilities. The device is configured to trust any CORS origin, and is accessible via the personalcloud.local domain name. Due to this it is possible for any website to gain access to this information. While this information doesn’t allow an attacker to compromise the NAS, the information can be used to stage more targeted attacks. This issue was tested on a Seagate Personal Cloud model SRN21C running firmware versions 188.8.131.52 and 184.108.40.206. The software is licensed from LACIE, it is very likely that other devices/models are also affected.
