Summary
ProSoft ICX35 devices (X35-HWC-A and ICX35-HWC-E) have a login lockout bypass in their integrated module web page. A remote attacker, without logging in, can clear the lockout by deleting the related browser cookies and keep guessing passwords, which defeats brute-force protection.
Read the original description
ProSoft Technology ICX35 devices (X35-HWC-A and ICX35-HWC-E) contain a login lockout bypass in the integrated module web page. The account lockout mechanism that restricts repeated failed authentication attempts is enforced in client-side JavaScript, so a remote attacker can reset the lockout and continue submitting password guesses by deleting the relevant browser cookies, defeating the brute-force protection. This vulnerability has been addressed in version 1.14.158.
What to do
Upgrade to a fixed version: 1.14.158.

Questions about CVE-2026-119746
Is CVE-2026-119746 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
The login page's lockout protection relies on browser cookies, so clearing those cookies resets the lockout. This lets a person keep trying passwords without being locked out, which defeats brute-force protection.Source: vulncheck.com
Which versions are affected by CVE-2026-119746?
X35-HWC-A: through 1.14.153. ICX35-HWC-E: through 1.14.153.Source: cve.now feed data
Am I affected, and how do I check?
Modules X35-HWC-A and ICX35-HWC-E running firmware version 1.14.153 or earlier are affected. To check, look up the firmware version reported on the module's web interface or in its device information page.Source: vulncheck.com
How do I fix CVE-2026-119746?
Upgrade the affected modules to firmware version 1.14.158 or later, which addresses this vulnerability.Source: vulncheck.com
