The CERT-In advisory also adds that "It is noted that not all applications are encrypting their network communication. Still there is a possibility that attacker could possibly capture sensitive information from the affected device in plain text like email addresses, IMEI number, SMSes, installed applications."

Security experts also say that this flaw will allow data written in plain text to be captured and viewed. Android apps that directly connect to a server using SSL, however, will not be affected by this flaw.
