CVE-2024-42411

Summary

CVE-2024-42411 affects multiple versions of Mattermost, specifically 9.9.x up to 9.9.1, 9.5.x up to 9.5.7, 9.10.x up to 9.10.0, and 9.8.x up to 9.8.2, due to inadequate input restrictions in the POST /api/v4/users endpoint allowing users to manipulate account creation dates. This vulnerability poses a medium severity risk as it could mislead administrators into believing that a user account is older than it actually is, potentially aiding in social engineering attacks or unauthorized access attempts by impersonating legitimate users with longer-standing accounts. To remediate this issue, organizations should upgrade to the latest versions of Mattermost that address this vulnerability as outlined in vendor advisories available at Mattermost's security updates page. The exploitation of this vulnerability does not require elevated privileges or user interaction but operates over a network, highlighting the need for regular software updates and vigilant monitoring of user activity within corporate environments. Failure to address this issue may result in reputational damage or security breaches that compromise sensitive organizational data.
