Bendix EC80 Brake ECU uses hard-coded credentials, which could allow an attacker to disable automatic traction control.
AnalysisAI
Hard-coded credentials in the Bendix EC80ESP and EC80ESP+ Brake ECU family allow an adjacent-network attacker to bypass authentication and disable automatic traction control and electronic stability program functions on commercial heavy vehicles. All ten identified EC80ESP/EC80ESP+ variants across J1708, CAN, PLC, and TPMS configurations are affected, with no version exclusion identified in CPE data. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires adjacent-network access to the vehicle's CAN bus or J1708 serial interface, as confirmed by CVSS AV:A. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L, score 5.4) reflects adjacent-network access with low complexity and no required authentication, meaningfully constraining exploitation to attackers with physical or logical proximity to the vehicle's in-vehicle network. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Consult CISA ICS Advisory ICSA-26-237-05 (https://www.cisa.gov/news-events/ics-advisories/icsa-26-237-05) and the associated CSAF document (https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-237-05.json) for vendor-issued firmware updates - no exact fixed firmware version was confirmed in the available input data, so patch status must be verified directly with Bendix. … Detailed patch versions, workarounds, and compensating controls in full report. |
Threat intelligence, references, and detailed analysis are available after sign-in.
