A Permissions, Privileges, and Access Control vulnerability exists in Schneider Electric's Modicon M221 product (all references, all versions prior to firmware V1.6.2.0). The vulnerability allows unauthorized users to overwrite the original password with their password. If an attacker exploits this vulnerability and overwrite the password, the attacker can upload the original program from the PLC.CVE-2018-7790schneider electric semodicon m221, all references, all versions prior to firmware v1.6.2.0+1EPSS score2.48%
An Information Management Error vulnerability exists in Schneider Electric's Modicon M221 product (all references, all versions prior to firmware V1.6.2.0). The vulnerability allows unauthorized users to replay authentication sequences. If an attacker exploits this vulnerability and connects to a Modicon M221, the attacker can upload the original program from the PLC.CVE-2020-7566schneider-electricmodicon_m221_firmwareEPSS score0.30%
A CWE-334: Small Space of Random Values vulnerability exists in Modicon M221 (all references, all versions) that could allow the attacker to break the encryption keys when the attacker has captured the traffic between EcoStruxure Machine - Basic software and Modicon M221 controller.CVE-2020-7565schneider-electricmodicon_m221_firmwareEPSS score0.30%
A CWE-326: Inadequate Encryption Strength vulnerability exists in Modicon M221 (all references, all versions) that could allow the attacker to break the encryption key when the attacker has captured the traffic between EcoStruxure Machine - Basic software and Modicon M221 controller.CVE-2020-7567schneider-electricmodicon_m221_firmwareEPSS score0.21%
A CWE-311: Missing Encryption of Sensitive Data vulnerability exists in Modicon M221 (all references, all versions) that could allow the attacker to find the password hash when the attacker has captured the traffic between EcoStruxure Machine - Basic software and Modicon M221 controller and broke the encryption keys.CVE-2020-7568schneider-electricmodicon_m221_firmwareEPSS score0.53%
A CWE-200: Exposure of Sensitive Information to an Unauthorized Actor vulnerability exists in Modicon M221 (all references, all versions) that could allow non sensitive information disclosure when the attacker has captured the traffic between EcoStruxure Machine - Basic software and Modicon M221 controller.CVE-2017-6030schneider electricmodicon m221+5EPSS score2.14%
A predictable value range from previous values issue was discovered in Schneider Electric Modicon PLCs Modicon M221, firmware versions prior to Version 1.5.0.0, Modicon M241, firmware versions prior to Version 4.0.5.11, and Modicon M251, firmware versions prior to Version 4.0.5.11. The affected products generate insufficiently random TCP initial sequence numbers that may allow an attacker to predict the numbers from previous values. This may allow an attacker to spoof or disrupt TCP connections.CVE-2019-10953abb1sap120600r0071 pm554-tp-eth+18EPSS score3.40%
