The Indian Government said it has addressed a critical vulnerability in its secure document wallet service Digilocker that could have potentially let a remote attacker bypass mobile one-time passwords (OTP) and sign in as other users.
Discovered separately by two independent bug bounty researchers, Mohesh Mohan and Ashish Gahlot, the vulnerability could have been exploited easily to unauthorisedly access sensitive documents uploaded by targeted users’ on the Government-operated platform.
“The OTP function lacks authorisation which makes it possible to perform OTP validation with submitting any valid users details and then manipulation flow to sign in as a totally different user,” Mohesh Mohan said in a disclosure shared with The Hacker News.
With over 38 million registered users, Digilocker is a cloud-based repository that acts as a digital platform to facilitate online processing of documents and speedier delivery of various government-to-citizen services. It’s linked to a user’s mobile number and Aadhar ID—a unique identity number (UID) issued to every resident of India.
