Microsoft discovered a high-severity vulnerability in the TikTok Android application, which could have allowed attackers to compromise users’ accounts with a single click. The vulnerability, which would have required several issues to be chained together to exploit, has been fixed and we did not locate any evidence of in-the-wild exploitation. Attackers could have leveraged the vulnerability to hijack an account without users’ awareness if a targeted user simply clicked a specially crafted link. Attackers could have then accessed and modified users’ TikTok profiles and sensitive information, such as by publicizing private videos, sending messages, and uploading videos on behalf of users.
TikTok has two flavors of its Android app: one for East and Southeast Asia under the package name com.ss.android.ugc.trill, and another for the remaining countries under the package name com.zhiliaoapp.musically. Performing a vulnerability assessment of TikTok, we determined that the issues were affecting both flavors of the app for Android, which have over 1.5 billion installations combined via the Google Play Store. After carefully reviewing the implications, a Microsoft security researcher notified TikTok of the issues in February 2022, as part of our responsible disclosure policy through Coordinated Vulnerability Disclosure (CVD) via Microsoft Security Vulnerability Research (MSVR). TikTok quickly responded by releasing a fix to address the reported vulnerability, now identified as CVE-2022-28799, and users can refer to the CVE entry for more information. We commend the efficient and professional resolution from the TikTok security team. TikTok users are encouraged to ensure they’re using the latest version of the app.
