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.

The default configuration of Tridium Niagara AX Framework through 3.6 uses a cleartext base64 format for transmission of credentials in cookies, which allows remote attackers to obtain sensitive information by sniffing the network.

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.

Tridium Niagara AX Framework does not properly store credential data, which allows context-dependent attackers to bypass intended access restrictions by using the stored information for authentication.

Directory traversal vulnerability in Tridium Niagara AX Framework allows remote attackers to read files outside of the intended images, nav, and px folders by leveraging incorrect permissions, as demonstrated by reading the config.bog file.
