BApp details: Image Location & Privacy Scanner
Image Location & Privacy Scanner
Passively scans for GPS locations or embedded privacy related exposure (like camera serial numbers) in images during normal security assessments of websites via a Burp plug-in. Image Location & Privacy Scanner assists in situations where end users may post profile images and possibly give away their home's location, e.g. a dating site or children's chatroom.
More information on this topic, including a whitepaper based on a real-world site audit given as a presentation at the New Jersey chapter of the OWASP organization, can be found at https://www.veggiespam.com/ils.
This software finds the GPS information inside of Exif tags, IPTC codes, and proprietary camera codes. Then, this scanner flags the findings in the Burp Scanner as an information message. It would be up to the auditor to determine if location exposure is truly a security risk based on context.
