Security readout for executives and security teams
Plain-English summary
Certain Bender/ebee EV charge controllers contain hardcoded credentials. If an attacker can reach the device, the credentials could provide administrative access to the web UI, creating risk to confidentiality, integrity, and availability of charging infrastructure.
Executive priority
Treat as urgent for any reachable charging infrastructure. The issue can allow administrative compromise without user interaction, but remediation planning should be grounded in vendor guidance because the provided sources do not name a specific patch version.
Technical view
CVE-2021-34601 is a CWE-259 hardcoded credential issue affecting Bender/ebee CC612, CC613, ICC15xx, and ICC16xx firmware families 5.11.x, 5.12.x, 5.13.x, and 5.20.x, with CC612 5.20.1 and below specifically described. CVSS 3.1 is 9.8, network exploitable, unauthenticated, and high impact.
Likely exposure
Organizations operating Bender/ebee charge controllers in EV charging environments may be exposed, especially if management interfaces are reachable from untrusted networks. Exposure depends on deployed product models, firmware versions, and network segmentation.
Exploitation context
The source bundle does not show CISA KEV listing or cite active exploitation. However, the vulnerability is rated critical because hardcoded credentials can enable unauthenticated network access where the affected management interface is reachable.
Researcher notes
Do not assume all Bender products are affected. The provided affected scope is CC612, CC613, ICC15xx, and ICC16xx firmware families listed in the CVE bundle. Evidence for fixes, public exploit code, or observed exploitation is incomplete in the provided sources.
Mitigation direction
- Identify deployed Bender/ebee CC612, CC613, ICC15xx, and ICC16xx controllers.
- Check vendor or VDE advisory guidance for corrected firmware or official mitigation.
- Remove management interfaces from internet and untrusted network reachability.
- Restrict SSH and web UI access to trusted administration networks only.
- Monitor for unexpected administrative access to charging controllers.
Validation and detection
- Inventory controller models and firmware versions across charging sites.
- Compare firmware against affected 5.11.x, 5.12.x, 5.13.x, and 5.20.x families.
- Confirm whether CC612 devices run version 5.20.1 or below.
- Review firewall rules for SSH and web UI exposure.
- Verify vendor remediation status before closing the finding.
