A vulnerability has been identified in ioLogik 4000 Series (ioLogik E4200) firmware versions v1.6 and prior, potentially exposing users to security risks. This vulnerability may allow attackers to trick users into interacting with malicious content, leading to unintended actions or unauthorized data disclosures.

Weakness

The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain, which can lead to user confusion about which interface the user is interacting with.

Affected Software

Name Vendor Start Version End Version
Iologik_e4200_firmware Moxa * 1.6 (including)

Potential Mitigations

  • The use of X-Frame-Options allows developers of web content to restrict the usage of their application within the form of overlays, frames, or iFrames. The developer can indicate from which domains can frame the content.
  • The concept of X-Frame-Options is well documented, but implementation of this protection mechanism is in development to cover gaps. There is a need for allowing frames from multiple domains.
  • A developer can use a “frame-breaker” script in each page that should not be framed. This is very helpful for legacy browsers that do not support X-Frame-Options security feature previously mentioned.
  • It is also important to note that this tactic has been circumvented or bypassed. Improper usage of frames can persist in the web application through nested frames. The “frame-breaking” script does not intuitively account for multiple nested frames that can be presented to the user.
