Directory traversal vulnerability in Tridium Niagara AX 3.5, 3.6, and 3.7 allows remote attackers to read sensitive files, and consequently execute arbitrary code, by leveraging (1) valid credentials or (2) the guest feature.
Tridium Niagara AX Framework through 3.6 uses predictable values for (1) session IDs and (2) keys, which might allow remote attackers to bypass authentication via a brute-force attack.
