CVE-2020-11723Public exploit

Evidence placement via hardcoded ADB private keys

Published Apr 14, 2020 · Updated Aug 4, 2024

Hard-coded credentials in Cellebrite UFED 5.0 through 7.29 allow local users to authenticate to target-device ADB daemons. AndroidLib.dll imports three embedded MS PRIVATEKEYBLOB values through CryptImportKey, while a fourth PEM key resides in a KnockoutNG EPR archive. Local access to the embedded Windows installation is required to extract the keys; reuse through a stock ADB client allows authentication as the forensic appliance and placement of files on a device that permanently accepted a UFED key.
