Technical details

The vulnerability is classified as Use of Hard-coded Credentials (CWE-798) within the Daktronics DMP-5000 and DMP-8000 controller firmware. The devices ship with a default administrative web account with weak authentication controls that are not required to be changed during initial setup. A remote attacker with network access to the administrative interface can use these credentials to gain full system access. While the CVSS 3.1 vector indicates low privileges (PR:L), the impact is high for confidentiality and integrity (C:H/I:H). Daktronics has released firmware updates (8.117.0.x, 9.43.0.x, and 10.34.0.x) to address this and recommends users immediately change default passwords.
