CVE-2025-27580
NIH BRICS (aka Biomedical Research Informatics Computing System) through 14.0.0-67 generates predictable tokens (that depend on username, time, and the fixed 7Dl9#dj- string) and thus allows unauthenticated users with a Common Access Card (CAC) to escalate privileges and compromise any account, including administrators.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
