CVE-2014-5207
Linux Kernel < 3.16.1 - Privilege Escalation via Bind Mount Remount
Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2014-5207. PoCs published by Andy Lutomirski.
AI-analyzed exploit summary This exploit leverages a FUSE-based vulnerability (CVE-2014-5207) to gain root privileges by manipulating file descriptors and namespace isolation. It creates a FUSE filesystem with a SUID binary that, when executed, spawns a shell with elevated privileges.
Description
fs/namespace.c in the Linux kernel through 3.16.1 does not properly restrict clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and changing MNT_ATIME_MASK during a remount of a bind mount, which allows local users to gain privileges, interfere with backups and auditing on systems that had atime enabled, or cause a denial of service (excessive filesystem updating) on systems that had atime disabled via a "mount -o remount" command within a user namespace.
