CVE-2026-44436

Quicly (QUIC implementation used with H2O) is vulnerable to a Denial of Service due to connection state corruption caused by a 255-byte Connection ID handling in the decoder, while QUIC version 1 requires a 20-byte CID buffer. The library lacked enforcement for 20-byte CIDs, allowing mismatched I...

PT-2026-60602

Name of the Vulnerable Software and Affected Versions Quicly versions prior to commit 8b178e6 Description Quicly is vulnerable to a Denial of Service DoS attack caused by connection state corruption. While the QUIC version 1 protocol restricts Connection IDs CID to 20 bytes, the packet decoder in...

Rockwell Automation CompactLogix 5370 suffers a denial-of-service vulnerability

Rockwell Automation CompactLogix 5370 is a programmable automation controller developed by Rockwell Automation in the United States. The CompactLogix 5370 has a denial-of-service vulnerability, which stems from the lack of verification of sequence numbers and source IP addresses in the CIP...

CVE-2026-9307

The CVE-2026-9307 issue affects CompactLogix 5370 controllers where the web server exposes CIP Connection IDs on the diagnostics page to unauthenticated users, enabling an attacker to craft malicious packets and cause Denial-of-Service. The available documents do not specify affected firmware ver...

EUVD-2025-210167

A security issue exists within 1769 CompactLogix controllers due to the missing validation of sequence numbers and source IP addresses in the CIP protocol. This allows attacker to abuse the exposed Connection ID’s visible on the web interface to perform denial-of-service attacks, resulting in...

CVE-2025-11694 Rockwell Automation CompactLogix 5370 Controllers – Multiple Vulnerabilities

A security issue exists within 1769 CompactLogix controllers due to the missing validation of sequence numbers and source IP addresses in the CIP protocol. This allows attacker to abuse the exposed Connection ID’s visible on the web interface to perform denial-of-service attacks, resulting in...

CVE-2026-9307: Exposure of Sensitive System Information to an Unauthorized Control Sphere

A sensitive information disclosure security issue exists within the affected CompactLogix controllers. The controller's web server exposes CIP Connection IDs on the diagnostics webpage, which are accessible to any unauthenticated user on the network. This information can be leveraged by an attack...

Netty: QUIC stateless reset token material exposed through header-visible connection IDs

Summary Netty QUIC exposes the stateless reset token on the network path when using the default HMAC-based connection-ID and stateless-reset-token generators. The reset token for the server's current source connection ID can be derived from bytes that appear as the connection ID in QUIC headers...

CVE-2026-50009 Netty QUIC stateless reset token material exposed through header-visible connection IDs

Netty is a network application framework for development of protocol servers and clients. Prior to version 4.2.15.Final, Netty QUIC exposes the stateless reset token on the network path when using the default HMAC-based connection-ID and stateless-reset-token generators. The reset token for the...
