CVE-2025-3946 (GCVE-0-2025-3946)

Vulnerability from cvelistv5 – Published: 2025-07-10 20:16 – Updated: 2025-08-04 19:46
VLAI
Title
Incorrect response generation during FTEB protocol processing
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.

Vulnerability from github – Published: 2025-07-10 21:31 – Updated: 2025-07-10 21:31
VLAI
Details

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.

Vulnerability from github – Published: 2026-10-01 18:32 – Updated: 2026-10-01 21:32
VLAI
Details

Deployment of wrong handler vulnerability in Apache HTTP Server allows the target of some internal redirects from CGI programs to also be treated as CGI and executed. The target must already be in a directory enabled for CGI and have no other extension understood by mod_mime.

This issue affects Apache HTTP Server: from 2.4.60 through 2.4.68.

Mitigation
Architecture and Design

Perform a type check before interpreting an object.

Mitigation
Architecture and Design

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.
