Select Dell Client Consumer and Commercial platforms include an issue that allows the BIOS Admin password to be changed through Dell's manageability interface without knowledge of the current BIOS Admin password. This could potentially allow an unauthorized actor, with physical access and/or OS administrator privileges to the device, to gain privileged access to the platform and the hard drive.
The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes NUL characters or null bytes when they are sent to a downstream component.
https://cwe.mitre.org/data/definitions/158.html →Open in CWE collection →An adversary embeds one or more null bytes in input to the target software. This attack relies on the usage of a null-valued byte as a string terminator in many environments. The goal is for certain components of the target software to stop processing the input when it encounters the null byte(s).
https://capec.mitre.org/data/definitions/52.html →Open in CAPEC collection →If a string is passed through a filter of some kind, then a terminal NULL may not be valid. Using alternate representation of NULL allows an adversary to embed the NULL mid-string while postfixing the proper data so that the filter is avoided. One example is a filter that looks for a trailing slash character. If a string insertion is possible, but the slash must exist, an alternate encoding of NULL in mid-string may be used.
