AJA HELO Plus firmware before 2.1.7 contains an information disclosure vulnerability that allows unauthenticated attackers to decrypt sensitive diagnostics bundles by exploiting a static AES passphrase embedded in obfuscated form within the firmware. Attackers can reverse engineer the publicly available firmware image to recover the shared passphrase and decrypt diagnostics export bundles retrieved from the unauthenticated diagnostics endpoint on any affected device, exposing highly sensitive server information.

**Name of the Vulnerable Software and Affected Versions** AJA HELO Plus versions prior to 2.1.7 **Description** A stored cross-site scripting issue exists that allows unauthenticated attackers with network access to inject malicious JavaScript. This occurs when the `eParamID SystemName` variable is set with unsanitized data via the '/config?action=set' API endpoint. If device authentication is disabled, the injected script executes persistently in the browser of any administrator accessing the web management interface. This can lead to the theft of stored secrets, including web UI credentials, RTMP stream keys, publish URLs, and NFS/SMB share credentials, or the hijacking of authenticated sessions. **Recommendations** Update AJA HELO Plus to version 2.1.7 or later. Enable device authentication to prevent unauthenticated access to the configuration API.
