- CWE-430 - Deployment of Wrong Handler
Summary
The Honeywell Experion PKS
and OneWireless WDM
contains a Deployment of Wrong Handler
vulnerability
in the component Control Data Access (CDA). An attacker could potentially exploit this vulnerability, leading to
Input Data Manipulation,
which could result in incorrect handling of packets leading to remote code execution.
Honeywell recommends updating to the most recent version of Honeywell Experion PKS:520.2 TCU9 HF1 and 530.1 TCU3 HF1 and OneWireless: 322.5 and 331.1.
The affected Experion PKS products are C300 PCNT02, C300 PCNT05, FIM4, FIM8, UOC, CN100, HCA, C300PM, and C200E. The Experion PKS versions affected are from 520.1 through 520.2 TCU9 and from 530 through 530 TCU3. The OneWireless WDM affected versions are 322.1 through 322.4 and 330.1 through 330.3.

Mitigation
Phase: Architecture and Design
Description:
- Perform a type check before interpreting an object.
Mitigation
Phase: Architecture and Design
Description:
- Reject any inconsistent types, such as a file with a .GIF extension that appears to consist of PHP code.
CAPEC-11: Cause Web Server Misclassification
An attack of this type exploits a Web server's decision to take action based on filename or file extension. Because different file types are handled by different server processes, misclassification may force the Web server to take unexpected action, or expected actions in an unexpected sequence. This may cause the server to exhaust resources, supply debug or system data to the attacker, or bind an attacker to a remote process.
