What it is
From the CVE record
Dell System Update, versions prior to 2.3.0.0, contains an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Filesystem access for attacker. This vulnerability is considered critical because it can be leveraged by an unauthenticated attacker to execute arbitrary code with root privileges. Successful exploitation may allow complete compromise of the vulnerable application and underlying operating system. Dell recommends customers upgrade at the earliest opportunity.
