CVE-2026-47097: AJA HELO Plus < 2.1.7 Static AES Passphrase Information Disclosure via /diags
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.
Affected Software
Event History
Frequently Asked Questions
Which systems are exposed to this issue?
AJA HELO Plus devices running firmware earlier than 2.1.7 are affected. An attacker can target affected devices over the network because the diagnostics endpoint is unauthenticated.
What does an attacker need to exploit the vulnerability?
No credentials or user interaction are required. The attacker needs access to the affected device's unauthenticated diagnostics endpoint and can recover the shared AES passphrase by reverse engineering a publicly available firmware image.
What information could be exposed?
An attacker can retrieve and decrypt diagnostics export bundles from an affected device. Those bundles may expose highly sensitive server information.
