| Exploitation Conditions | Exploitation requires obtaining the EnergizeLab FirmwareUpdater AArch64 ELF - trivially available since it ships in the public CDN bin.zip - and reverse-engineering it to extract the single hard-coded AES key; no credentials are needed for this step (PR:N). To impact a victim, the attacker must then craft a firmware package encrypted with the recovered key and have a trusting device install it, which requires user/operator interaction with the update process (UI:R). Limiting factors: the attack is locally vectored (AV:L) rather than remote, success depends on the forged image reaching and being installed on a device, and impact is confined to devices that trust that shared key; there is no evidence of a remote network-triggerable path in the provided data. |
| Impact | The CVSS 3.1 score of 7.8 (AV:L/AC:L/PR:N/UI:R) frames this as a locally-vectored, user-interaction-dependent flaw with full C/I/A impact, driven by CWE-321 use of a single hard-coded AES key shared across all installations. The practical risk is higher than 'local' suggests: the FirmwareUpdater ELF is distributed openly in the CDN bin.zip, so recovering the key requires only downloading and reverse-engineering a public binary - effectively trivial attack complexity and no barrier to key acquisition. However, weaponization against victims still depends on delivering a forged firmware image that a device will accept and install (UI:R), which limits opportunistic mass exploitation unless an update-delivery channel can be hijacked. No EPSS score, KEV listing, or confirmed POC is present in the input, so exploitation probability cannot be quantified; a GitHub reference ('your-secrets-are-safe-with-me') may host key-extraction material but its contents are unverified and it is NOT a confirmed exploit. Signal conflict to flag: the sole impact tag is 'Information Disclosure,' yet the primary consequence is firmware forgery (integrity/availability), so the tagging understates the true impact - verify impact classification. Net: a genuine high-impact integrity issue for anyone running EnergizeLab devices, but the local vector plus install-time user interaction keep it below the 'drop-everything' tier absent evidence of active exploitation. |
| Exploit ScenarioDerived | An attacker downloads the publicly distributed FirmwareUpdater AArch64 ELF from the vendor CDN (bin.zip), reverse-engineers it to recover the shared hard-coded AES key, and encrypts a malicious firmware image with that key. Because every installation trusts the same key, the forged image is accepted and installed, giving the attacker control over any targeted EnergizeLab device. No vendor-confirmed POC is identified, though a referenced GitHub repository may contain key-extraction material. |

Alert meAnalysisAIv1 – Oct 15, 2026
Firmware forgery is possible in the EnergizeLab FirmwareUpdater (AArch64 ELF, distributed in the public CDN bin.zip) because every installation ships with the same hard-coded AES key, so an attacker who recovers that key can decrypt and craft firmware packages accepted by any device that trusts the updater. Key recovery needs no credentials since the binary is publicly downloadable (PR:N), but the forged image must actually reach a device and be installed by an operator (UI:R), yielding a locally-vectored CVSS 3.1 score of 7.8 with high confidentiality, integrity and availability impact. No public exploit code and no confirmed active exploitation (CISA KEV) were identified at time of analysis; the result is a systemic, fleet-wide trust failure rather than a remotely triggerable network flaw.
RemediationAI
No vendor-released patch was identified at time of analysis, so remediation must start from the assumption that the shared AES key is already effectively public. The durable fix is a firmware-trust redesign: replace the single embedded symmetric key with per-device keys or, preferably, asymmetric signing where the device holds only a public verification key and the signing private key never leaves an offline HSM, and rotate the compromised AES key - noting the chicken-and-egg trade-off that any key-rotation image must itself be delivered over the existing (already compromised) update channel, so rotation should be performed in a controlled maintenance window with out-of-band verification. Until such firmware exists, apply compensating controls: stop accepting firmware packages from unauthenticated or untrusted sources, restrict the update path so images are fetched only from a locked-down, access-controlled distribution point with a pinned hash published over a separate trusted channel, and have operators manually verify each image's digest and provenance before installation, accepting that this adds manual effort and does not stop an attacker who can already place a file on the device. Detection is limited - monitor for unexpected firmware images, unusual update timings, or device behaviour changes, since a correctly keyed forged package is cryptographically indistinguishable to the updater itself.

Technical ContextAI · show details
The root cause is CWE-321 (Use of Hard-coded Cryptographic Key) in the EnergizeLab FirmwareUpdater, an AArch64 ELF binary that is not held privately but distributed openly inside the CDN bin.zip archive. Because a symmetric AES key is embedded in the binary rather than derived per device, the same secret protects every installation's firmware packages, so reverse-engineering a single copy of the updater - a routine static-analysis task on an unstripped or lightly obfuscated ELF - yields the key material for the entire population of trusting devices. That key is then usable both to decrypt legitimate firmware images (confidentiality loss) and to encrypt attacker-authored images that pass the updater's integrity check (integrity loss), with the device subsequently executing the forged payload (availability loss). The CPE record cpe:2.3:a:energizelab:firmwareupdater:*:*:*:*:*:*:*:* marks all versions of the updater as affected, i.e. there is no known release that migrates to per-device keys or asymmetric signing. The absence of any device-identity binding means compromise scales horizontally: one extracted secret defeats the update trust model across the whole product line, and there is no evidence in the provided data of a remote, unauthenticated network path that would bypass the need to obtain the binary and to have a forged image installed.

DescriptionCVE.org
The EnergizeLab FirmwareUpdater (AArch64 ELF, distributed in the CDN bin.zip) uses a single hard-coded AES key shared by all installations. An attacker who recovers the key from the updater can decrypt and forge firmware packages for any device that trusts it.
Executive ViewAI
EnergizeLab FirmwareUpdater, used across the EnergizeLab device fleet, relies on a shared secret embedded in a publicly downloadable binary, enabling forged firmware to be accepted by any trusting device. If exploited, a malicious update could be installed by an operator, compromising confidentiality, integrity, and availability fleet-wide and creating systemic supply-chain and update-trust risk. No public exploit identified at time of analysis, but leadership should treat this as a high-priority integrity issue because no vendor-released patch is available.
No vendor-released patch identified at time of analysis. Interim mitigations: restrict and monitor firmware packages, enforce independent hash or signature verification via a trusted out-of-band channel, require operator dual authorization for firmware installs, isolate or segment affected devices, enable secure boot or attestation where possible, monitor for unauthorized firmware changes, and obtain vendor guidance on unique per-device key rotation.
