Module: check_mk Branch: master Commit: cb1a576289ad7cd96e142b0376a45d6eaaf09a10 URL: http://git.mathias-kettner.de/git/?p=check_mk.git;a=commit;h=cb1a576289ad7c… Author: Lars Michelsen <lm(a)mathias-kettner.de> Date: Thu Oct 18 09:23:19 2018 +0200 6787 SEC Notification spooler: Fixed file path traversal vulnerability The notification daemon of one site connects to the notification daemon of another site to exchange notifications between both sites. The notification daemon was not validating the incoming data correctly which made it possible for an attacker that has access to the notification sending site to compromise the receiving site. Using this vulnerability it was possible to write write files in directories that are writable by the receiving site user. This could be used to gain access to the site.
