Hitachi Coding Software Suite: Cleartext transmission of sensitive information
Summary
Hitachi Coding Software Suite up to and including version 3.3.0 transmits authentication credentials and sensitive data without encryption. An attacker positioned on the network path between the suite and its connected printers or vision systems can read this traffic and obtain login data. The CVSS 4.0 base score is 8.7, but the impact is limited to confidentiality and the attack requires a network position.
Affected
- Hitachi Coding Software Suite through version 3.3.0 (advisory: V3.3.0 and earlier)
Fixed in
- Unknown. The vendor advisory was not fully reviewed; verify the fixed version in the Hitachi advisory before patching.
- Third-party sources indicate a fix in version 4.0.0 or later, not yet confirmed by the vendor.
Workaround
- Unknown from vendor guidance.
- Analyst commentary (VulDB) recommends upgrading to a version later than 3.3.0 and enforcing encrypted communication.
- Keep suite and printer/vision-system traffic on a segregated OT/production VLAN and restrict access to trusted hosts.
- Do not log in over untrusted Wi-Fi or shared networks; change credentials used through the suite.
Exploitation
- No known exploitation in the wild.
- Not listed in CISA KEV.
- VulDB states that no exploit is available.
- EPSS is very low (0.00173).
Our recommendation
- Check whether Hitachi Coding Software Suite is in use, including at customers, and which version is installed.
- Review the Hitachi advisory and update to the fixed version as soon as the vendor confirms it; patch the whole suite, as other CVEs in the same advisory are rated higher.
- Until patched, isolate the suite and connected printers on a segregated network and avoid untrusted networks for logins.
- Monitor for unusual logins and change credentials used with the suite.
