Exploitation Conditions

Not remotely exploitable against a default deployment despite AV:N. Path 1 requires the attacker to reverse-engineer the firmware to obtain the hardcoded dev/test Wi-Fi credentials AND independently discover the physical location of that vendor Wi-Fi network to connect to it. Path 2 (evil-twin) requires close physical proximity to the specific device at the moment of first setup, plus standing up a rogue AP configured with the recovered SSID and password so the device auto-connects. Both are limited to Wi-Fi/adjacent range and are timing- or location-dependent; there is no purely-remote internet-facing exploitation of the device itself.

Impact

The 9.8 CRITICAL rating is grossly overstated relative to the actual described attack. The NVD vector claims AV:N/AC:L/PR:N/UI:N with full C:H/I:H/A:H, but the description itself limits both exploitation paths to proximity-bound Wi-Fi scenarios: either (1) extract hardcoded credentials from firmware AND physically locate the vendor's dev/test Wi-Fi network, or (2) be in close physical proximity to the device during first setup to run an evil-twin AP. Both are adjacent/physical (AV:A, not AV:N) and require additional non-trivial conditions (AC should be H, not L). Impact is on a consumer meat thermometer, so real confidentiality/integrity/availability impact is minor, not H across the board - the NVD C:H/I:H/A:H appears to be scored against 'the vendor's Wi-Fi network' rather than the device, which is a questionable framing. EPSS is low at 0.43% (35th percentile), there is NO CISA KEV listing, and there is no SSVC decision content in the input. Public writeups by researcher dead1nfluence document and disclose the extracted hardcoded credentials, so exploit-grade detail is public even though this is not evidence of active exploitation. Net: this is a high-CVSS-but-low-real-risk issue - a legitimate weak-credentials finding on a niche consumer IoT device, not an urgent remotely-exploitable RCE. The AV:N in the vector directly conflicts with the description's explicit proximity requirements and should be verified/downgraded.

Exploit ScenarioDerived

An attacker extracts the firmware image (v1.0.34.4) and recovers the hardcoded Wi-Fi SSID and password left in from the vendor's development/test network, as publicly documented in the dead1nfluence writeups. Positioned in close physical proximity as a victim first powers on and configures the thermometer, the attacker stands up a rogue access point broadcasting that same SSID/password, forcing the device to auto-connect to attacker-controlled infrastructure for a man-in-the-middle position over the device's traffic.

AnalysisAIv1 – Sep 25, 2026

Hardcoded Wi-Fi credentials embedded in Meatmeet Pro WiFi & Bluetooth meat thermometer firmware version 1.0.34.4 (CWE-798) can be recovered by anyone who obtains and reverse-engineers the firmware image, after which an attacker could join the vendor's internal test network if they also independently locate that physical network, or-if they are within close physical proximity during the device's first setup-stand up a rogue access point using the recovered SSID and password so the thermometer auto-connects to attacker-controlled infrastructure. The device is not exploitable over the public internet: our assessment rates the flaw CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N (~4.2 Medium), so the published 9.8 CRITICAL score is grossly overstated relative to the described attack paths. There is no confirmed active exploitation (not in CISA KEV), no public exploit code identified at time of analysis, and EPSS is only 0.43% (35th percentile), indicating low practical exploitation likelihood.

RemediationAI

No vendor-released patch was identified at time of analysis, so there is no fixed firmware version to cite; operators should press Meatmeet for a firmware update that removes the embedded test-network SSID/passphrase from the image and provisions credentials uniquely per device at setup. Until then, compensating controls are: rotate or decommission the vendor's development/test Wi-Fi network that matches the leaked SSID and passphrase (removing the credential's value entirely, at the cost of reconfiguring any legitimate devices that relied on it); keep the thermometer on an isolated IoT VLAN/guest network with client isolation so an auto-connected rogue AP cannot reach other assets (this limits lateral movement but does not stop the device from connecting); and avoid performing first-time provisioning in public or untrusted locations where an attacker could be within radio range (a logistics fix, not a technical one). Because exploitation demands firmware reverse engineering plus either locating the vendor network or physical proximity, and EPSS is only 0.43% with no KEV listing or public exploit code, remediation can be prioritized behind internet-facing criticals rather than treated as an emergency.

Technical ContextAI · show details

The affected component is the ESP32-based firmware (version 1.0.34.4) of the Meatmeet Pro WiFi & Bluetooth meat thermometer, identified by CPE cpe:2.3:o:meatmeet:meatmeet_pro_wifi_&_bluetooth_meat_thermometer_firmware:1.0.34.4. The root cause is CWE-798 (Use of Hard-coded Credentials): development/test Wi-Fi SSID and passphrase values were left in the production firmware image rather than being stripped or provisioned uniquely at runtime. Because ESP32 station mode persists Wi-Fi credentials and automatically reconnects to a remembered SSID when it is in range, disclosed credentials create two distinct exposures-unauthorized access to whatever network that test SSID belongs to, and an evil-twin/auto-connect hijack when an attacker within radio range broadcasts an AP using the identical SSID and passphrase. Exploitation requires firmware reverse engineering plus either independent discovery of the vendor's test network location or physical proximity to the device at the moment of initial provisioning; it is an adjacent-network, high-complexity scenario with limited confidentiality and integrity impact and no availability impact, not a remotely reachable network-service vulnerability.

DescriptionCVE.org

The Meatmeet Pro was found to be shipped with hardcoded Wi-Fi credentials in the firmware, for the test network it was developed on. If an attacker retrieved this, and found the physical location of the Wi-Fi network, they could gain unauthorized access to the Wi-Fi network of the vendor. Additionally, if an attacker were located in close physical proximity to the device when it was first set up, they may be able to force the device to auto-connect to an attacker-controlled access point by setting the SSID and password to the same as which was found in the firmware file.

Executive ViewAI

Why It Matters

Hardcoded Wi-Fi credentials baked into Meatmeet Pro WiFi & Bluetooth meat thermometer firmware version 1.0.34.4 can be extracted by anyone who obtains a device image, putting the vendor's internal test network at risk of unauthorized access and enabling a nearby attacker to redirect a device during first-time setup. The published 9.8 CRITICAL rating is inconsistent with a threat that requires physical proximity or independent discovery of a private network and cannot be triggered over the public internet. Leadership should treat this as a product-security and brand-trust issue affecting the vendor's own test infrastructure and customer confidence rather than an internet-scale exposure, particularly since no vendor fix is currently available.

Business Impact: Medium
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: rotate the SSID and pre-shared key for the vendor's internal test network and any network the devices auto-join; strictly segment test-network traffic from production, corporate, and customer environments; disable auto-connect or stored-network behavior on deployed units where supported; restrict physical access to devices during first-time setup and re-provisioning; monitor for rogue access points and unexpected client associations; and treat any extracted firmware images as compromised credentials pending key rotation.
