Attackers Denied of Full Control Over ‘Wire’ Users’ Accounts

This article has been indexed from E Hacking News – Latest Hacker News and IT Security News

The developers of the Wire secure messaging app have patched the software against two critical security flaws, one of which could allow an attacker to takeover target users’ accounts. Specifically, the first of the two includes a cross-site scripting (XSS) vulnerability that allowed an attacker to fully control user accounts. The flaw tracked as, CVE-2021-32683, typically impacted the web app version 2021-05-10 and earlier.

According to security experts, threat actors often execute an XSS attack by sending a malicious link to a user and prompting the user to click it. If the app or website lacks proper security protocols, the malicious link executes the attacker’s chosen code on the user’s device. As a result, the attacker can steal the user’s active session cookie. 

Kane Gamble, an independent security researcher discovered two security issues in Wire Messenger versions for web and iOS. Headquartered in Germany with branches in the US, Sweden, and Switzerland, Wire is a popular messaging platform featuring audio, video, and text communications secured via end-to-end encryption with more than 500,000 users. 

The second flaw discovered by the researcher was a less critical denial of service (DoS) issue (CVE-2021-32666) in the iOS version of Wire.
