TeamViewer Remote vulnerability analysis and mitigation

CVE-2022-23242 is a security vulnerability discovered in TeamViewer Linux versions before 15.28. The vulnerability was disclosed and fixed in March 2022, affecting the password deletion mechanism in TeamViewer's Linux client. The issue specifically relates to improper execution of connection password deletion commands during process crashes (TeamViewer Bulletin).

The vulnerability has a CVSS v3.1 base score of 6.3 (Medium severity). The technical issue involves a failure to properly execute the deletion command for connection passwords when the TeamViewer process crashes. The vulnerability requires local access and user interaction, with attack complexity rated as low. The CVSS vector string is CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:H (TeamViewer Bulletin).

If exploited, the vulnerability could allow an attacker to establish a remote connection by reusing the improperly deleted connection password. This requires knowledge of the crash event, the TeamViewer ID, and either possession of the pre-crash connection password or local authenticated access to the machine (TeamViewer Bulletin).

The vulnerability has been fixed in TeamViewer version 15.28 and later. Users are recommended to update their Linux client installations to the latest version. Additionally, users leveraging passwordless authentication (Easy Access) and/or MFA for connections are not affected by this vulnerability (TeamViewer Bulletin).
