Description Adam Mariš 2015-10-08 08:10:25 UTC

In the default-direct.lua file in the "event.etype == 'Move'" branch, instead of using a direct fork/exec, a shell is spawned. Its arguments aren't quoted so one can inject additional parameters using whitespace characters.

Comment 1 Adam Mariš 2015-10-08 08:11:10 UTC

Created lsyncd tracking bugs for this issue:

Affects: fedora-all [bug 1269781]
Affects: epel-all [bug 1269782]

Comment 2 Jason Taylor 2017-04-12 13:53:50 UTC

I believe this issue can be closed as the versions in fedora/epel have all been patched/updated.
