CVE-2008-1141

DESlock+ < 3.2.6 - Denial of Service via DLMFENC_IOCTL Requests

Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 2 public exploits for CVE-2008-1141. PoCs published by mu-b.

AI-analyzed exploit summary This exploit demonstrates a local kernel buffer overflow in DESlock+ <= 3.2.7 by sending a maliciously crafted IOCTL request to the DLKPFSD_Device driver. The PoC triggers a crash by overflowing a buffer with a large filename, but does not include a payload for execution.

Description

Memory leak in DLMFENC.sys 1.0.0.26 in DESlock+ 3.2.6 and earlier allows local users to cause a denial of service (kernel memory consumption) via a series of DLMFENC_IOCTL requests to \\.\DLKPFSD_Device that allocate "link list structures."
