Description

Exim 4 before 4.94.2 allows Execution with Unnecessary Privileges. Because Exim operates as root in the log directory (owned by a non-root user), a symlink or hard link attack allows overwriting critical root-owned files anywhere on the filesystem.

Solution(s)

  • ubuntu-upgrade-exim4-base
  • ubuntu-upgrade-exim4-daemon-heavy
  • ubuntu-upgrade-exim4-daemon-light

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
