CVE-2018-8780: Unintentional directory traversal by poisoned NUL byte in Dir

Posted by usa on 28 Mar 2018

There is an unintentional directory traversal in some methods in Dir. This vulnerability has been assigned the CVE identifier CVE-2018-8780.
Details

Dir.open, Dir.new, Dir.entries and Dir.empty? accept the path of the target directory as their parameter. If the parameter contains NUL (\0) bytes, these methods recognize that the path is completed before the NUL bytes. So, if a script accepts an external input as the argument of these methods, the attacker can make the unintentional directory traversal.

All users running an affected release should upgrade immediately.
Affected Versions

    Ruby 2.2 series: 2.2.9 and earlier
    Ruby 2.3 series: 2.3.6 and earlier
    Ruby 2.4 series: 2.4.3 and earlier
    Ruby 2.5 series: 2.5.0 and earlier
    Ruby 2.6 series: 2.6.0-preview1
    prior to trunk revision r62989
