AI-suggested

European organizations should ensure that all macOS endpoints running Safari have the AdGuard plugin updated to version 1.11.22 or later, where verbose URL logging is disabled. Endpoint management solutions should be used to enforce this update and verify plugin versions. Additionally, organizations should audit local log access permissions to restrict unsandboxed processes from reading general system logs. Implementing strict endpoint security controls, including application whitelisting and privilege management, can reduce the risk of unauthorized local access. Monitoring for unusual local process behavior that attempts to read system logs may help detect exploitation attempts. User awareness training should emphasize the risks of installing unverified plugins and the importance of timely updates. Finally, organizations should review their logging policies to avoid unnecessary exposure of sensitive information in logs.

Description

An issue was discovered in AdGuard plugin before 1.11.22 for Safari on MacOS. AdGaurd verbosely logged each url that Safari accessed when the plugin was active. These logs went into the MacOS general logs for any unsandboxed process to read. This may be disabled in version 1.11.22.
