hammerhead.cc in Hammerhead 2.1.4 allows local users to write to arbitrary files via a symlink attack on (1) /tmp/hammer.log (aka the HH_LOG file) or (2) the REPORT_LOG file.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
