Description

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.

Affected products

Alexander V. Lukyanov Lftp: through 4.0.5; 2.0.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5 (+135)
