Intego Antivirus through 3.0.0.1 Local Privilege Escalation via Optimization Module Junction

Intego Antivirus for Windows through 3.0.0.1 contains a link following vulnerability in its optimization module that allows local unprivileged users to delete arbitrary folders as SYSTEM. Attackers can replace a scanned duplicate file's directory with a junction to C:\Config.msi and abuse Windows Installer rollback to execute code as SYSTEM.

Intego VirusBarrier X4 allows context-dependent attackers to bypass virus protection by quickly injecting many infected files into the filesystem, which prevents VirusBarrier from processing all the files.

Intego Personal Backup Task File Privilege Escalation

Intego Personal Backup, a macOS backup utility that allows users to create scheduled backups and bootable system clones, contains a local privilege escalation vulnerability. Backup task definitions are stored in a location writable by non-privileged users while being processed with elevated privileges. By crafting a malicious serialized task file, a local attacker can trigger arbitrary file writes to sensitive system locations, leading to privilege escalation to root.

Intego Log Reporter TOCTOU Local Privilege Escalation

Intego Log Reporter, a macOS diagnostic utility bundled with Intego security products that collects system and application logs for support analysis, contains a local privilege escalation vulnerability. A root-executed diagnostic script creates and writes files in /tmp without enforcing secure directory handling, introducing a time-of-check to time-of-use (TOCTOU) race condition. A local unprivileged user can exploit a symlink-based race condition to cause arbitrary file writes to privileged system locations, resulting in privilege escalation to root.

Intego FileGuard 4.0 uses weak encryption to store user information and passwords, which allows local users to gain privileges by decrypting the information, e.g., with the Disengage tool.
