Analysis Summary

CVE-2025-40583 CVSS:4.4

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2). Affected devices do transmit sensitive information in cleartext.

CVE-2025-40580 CVSS:6.7

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2). Affected devices are vulnerable to a stack-based buffer overflow. This could allow a non-privileged local attacker to execute arbitrary code on the device or to cause a denial of service condition.

CVE-2025-40579 CVSS:6.7

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2). Affected devices are vulnerable to a stack-based buffer overflow. This could allow a non-privileged local attacker to execute arbitrary code on the device or to cause a denial of service condition.

CVE-2025-40578 CVSS:4.3

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2). Affected devices do not properly handle multiple incoming Profinet packets received in rapid succession. An unauthenticated remote attacker can exploit this flaw by sending multiple packets in a very short time frame, which leads to a crash of the dcpd process.

CVE-2025-40577 CVSS:4.3

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2). Affected devices do not properly validate incoming Profinet packets. An unauthenticated remote attacker can exploit this flaw by sending a specially crafted malicious packet, which leads to a crash of the dcpd process.

CVE-2025-40576 CVSS:4.3

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2). Affected devices do not properly validate incoming Profinet packets. An unauthenticated remote attacker can exploit this flaw by sending a specially crafted malicious packet, which leads to a crash of the dcpd process.

CVE-2025-40575 CVSS:5.3

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2). Affected devices do not properly validate incoming Profinet packets. An unauthenticated remote attacker can exploit this flaw by sending a specially crafted malicious packet, which leads to a crash of the dcpd process.

CVE-2025-40573 CVSS:4.4

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2). Affected devices are vulnerable to path traversal attacks. This could allow a privileged local attacker to restore backups outside the backup folder.
