Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2011-0418. PoCs published by Maksymilian Arciemowicz.
AI-analyzed exploit summary This exploit demonstrates a denial-of-service (DoS) vulnerability in FreeBSD's ftpd by sending a specially crafted STAT command with excessive wildcards, causing CPU resource exhaustion. The issue stems from the glob(3) function in FreeBSD's libc, which fails to enforce GLOB_LIMIT properly.
Description
The glob implementation in Pure-FTPd before 1.0.32, and in libc in NetBSD 5.1, does not properly expand expressions containing curly brackets, which allows remote authenticated users to cause a denial of service (memory consumption) via a crafted FTP STAT command.
