4 known affected

The vendor explicitly identifies these products as affected by this CVE.

  • FBXi Firmware Version <= 9.3.4
  • FBVi Firmware Version <= 9.3.4
  • FBTi Firmware Version <= 9.3.4
  • CBXi Firmware Version <= 9.3.4
Summary
Some information may be improperly disclosed through https access. This issue affects FLXEON<= 9.3.4
Remediation
- Stop and disconnect any FLXEON products that are exposed directly to the Internet, either via a direct ISP connection or via NAT port forwarding - Ensure that physical controls are in place, so no unauthorized personnel can access your devices, components, peripheral equipment, and networks - Ensure that all FLXEON products are upgraded to the latest firmware version (9.3.5 or above). Please find the latest version of FLXEON firmware on the respective product homepage - When remote access is required, only use secure methods. If a Virtual Private Network (VPN) is used, ensure that the chosen VPN is secure i.e. updated to the most current version available and configured for se-cure access.

01

What, why and how

Insertion of Sensitive Information into Log File vulnerability observed in FLEXON. Some information may be improperly disclosed through https access. This issue affects FLXEON through <= 9.3.4.

What

Insertion of Sensitive Information into Log File vulnerability observed in FLEXON. Some information may be improperly disclosed through https access. This issue affects FLXEON through <= 9.3.4.

Why

The product writes sensitive information to a log file.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may obtain information outside the intended access boundary.

What

Why

The product writes sensitive information to a log file.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may obtain information outside the intended access boundary.

02

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Insertion of Sensitive Information into Log File → obtain information outside the intended access boundary
