TikTok has addressed a couple of security issues that could have been chained to led account takeover. 





The first issue addressed by the social media platform is a reflected XSS security flaw that has been reported by the bug bounty hunter Muhammed “milly” Taskiran via the bug bounty platform HackerOne.





The Cross-Site-Scripting flaw affected the company domains www.tiktok.com and m.tiktok.com and its exploitation could have lead to data exfiltration.





“The researcher discovered a URL parameter reflecting its value without being properly sanitized and was able to achieve reflected XSS. In addition, researcher found an endpoint which was vulnerable to CSRF.” reads the description published by HackerOne. “The endpoint allowed to set a new password on accounts which had used third-party apps to sign-up. Researcher combined both vulnerabilities to achieve a “one click account takeover”.”





Using a fuzzing testing approach, the expert discovered a URL parameter reflecting its value without being properly sanitized. The white-hat hacker was able to achieve reflected XSS and also found an endpoint that was vulnerable to Cross-site request forgery (CSRF).





“The endpoint enabled me to set a new password on accounts which had used third-party apps to sign-up.” Taskiran explained. “I combined both vulnerabilities by crafting a simple JavaScript payload – triggering the CSRF – which I injected into the vulnerable URL parameter from earlier, to archive a “one click account takeover.”





Taskiran created a simple JavaScript payload that chained the XSS and the CSRF vulnerabilities. The script first triggers the CSRF issue, then injected into the vulnerable URL parameter leading to a one-click account takeover. 





Taskiran received a $3,860 payout for the reported vulnerabilities.
