Dell Client Consumer and Commercial Platforms contain an Arbitrary File Overwrite Vulnerability. The vulnerability is limited to the Dell Firmware Update Utility during the time window while being executed by an administrator. During this time window, a locally authenticated low-privileged malicious user could exploit this vulnerability by tricking an administrator into overwriting arbitrary files via a symlink attack. The vulnerability does not affect the actual binary payload that the update utility delivers.

A BIOS password extraction vulnerability has been reported on certain consumer notebooks with firmware F.22 and others. The BIOS password was stored in CMOS in a way that allowed it to be extracted. This applies to consumer notebooks launched in early 2014.
