The vulnerability (CVE-2025-XXXX) in Paragon Software products, including Paragon Partition Manager 17.9.1, stems from improper validation of user-supplied data length in the `biontdrv.sys` driver. Attackers can exploit this flaw to map arbitrary kernel memory, leading to privilege escalation. The driver fails to enforce proper bounds checks, allowing malicious actors to manipulate kernel memory structures and execute arbitrary code with elevated privileges.
DailyCVE Form:
Platform: Paragon Software
Version: 15 – 17.9.1
Vulnerability: Kernel Memory Mapping
Severity: Critical
Date: 2025-03-27
Prediction: Patch by 2025-06-30
What Undercode Say:
Check vulnerable driver version wmic path win32_pnpsigneddriver get devicename, driverversion | findstr "biontdrv.sys" Exploit PoC (hypothetical) ioctl(device_handle, VULN_IOCTL_CODE, user_controlled_buffer);
How Exploit:
- Abuse `biontdrv.sys` IOCTL to overwrite kernel memory.
- Craft malicious buffer to bypass length checks.
- Elevate privileges via controlled memory corruption.
Protection from this CVE:
- Apply vendor patches immediately.
- Restrict access to
biontdrv.sys. - Disable unnecessary kernel drivers.
Impact:
- Full system compromise.
- Privilege escalation to NT AUTHORITY\SYSTEM.
- Bypass security controls.
