Description Preview

CVE-2014-9642 describes a local privilege escalation vulnerability in the bdagent.sys driver used by BullGuard Antivirus, Internet Security, Premium Protection, and Online Backup prior to version 15.0.288. An unprivileged local user can exploit a crafted IOCTL call (0x0022405c) to write data to arbitrary memory locations and thereby elevate privileges.

Overview

This vulnerability concerns BullGuard's bdagent.sys driver, where a crafted IOCTL (0x0022405c) enables a local user to write to arbitrary memory and escalate privileges on affected products released before 15.0.288.

Remediation

  • Upgrade BullGuard products to version 15.0.288 or newer and apply any subsequent patches released by BullGuard.
  • If immediate upgrade is not possible, contact BullGuard for a patched hotfix or official workaround and implement compensating controls: restrict local access to affected machines, limit administrative or installation privileges, and ensure only trusted users can interact with security software services.
  • Deploy and verify the patch across all endpoints, then perform a vulnerability/compromise assessment to confirm remediation.
  • Monitor for unusual privilege-escalation activity and IOCTL misuse; enable security monitoring and alerts for anomalous driver interactions.
  • Keep the OS and security stack up to date (enable ASLR/DEP, apply latest OS patches) to reduce similar attack surfaces.
