Two vulnerabilities in mbCONNECT24 and mymbCONNECT24 can lead to information disclosure and arbitrary code execution.
Please consult the CVE entries for details.
A Denial of Service and a CA Check Problem have been identified in multiple openSSL 1.1.1 versions, which are utilized in the Phoenix Contact products listed above.
The vulnerability is a Time-of-Check-Time-of-Use (CWE-367) issue which allows an attacker with access to the firmware update file to overwrite it after it has been verified (but before installation is completed), which consequently allows installing an arbitrary firmware update, bypassing the cryptographic signature check mechanism.
Multiple vulnerabilities have been discovered in the current firmware of the PHOENIX CONTACT FL SWITCH SMCS series switches.
When the communication partner sends an invalid Modbus exception response to the FL COMSERVER UNI as a query, the Modbus communication stops, and the device will be unresponsive for some minutes before the functionality is fully restored (CWE-772).
An undocumented password protected FTP access to the root directory exists in certain devices of the AXL F BK and IL BK product families (CWE-798).
Phoenix Contact Classic Line industrial controllers are developed and designed for the use in closed industrial networks. The communication protocols and device access do not feature authentication measures. Remote attackers can use specially crafted IP packets to cause a denial of service on the PLC's network communication module (CWE-770).
