CVE-2010-2251: Alexander v. lukyanov lftp improper input validation vulnerability
AAlexander V. Lukyanov · Lftp
The get1 command, as used by lftpget, in LFTP before 4.0.6 does not properly validate a server-provided filename before determining the destination filename of a download, which allows remote servers to create or overwrite arbitrary files via a Content-Disposition header that suggests a crafted filename, and possibly execute arbitrary code as a consequence of writing to a dotfile in a home directory.
