CVSS: 9.8EPSS: 0%CPEs: 202EXPL: 0CVE-2020-16226 – Mitsubishi Electric Multiple Products
https://notcve.org/view.php?id=CVE-2020-16226
Multiple Mitsubishi Electric products are vulnerable to impersonations of a legitimate device by a malicious actor, which may allow an attacker to remotely execute arbitrary commands. Múltiples productos de Mitsubishi Electric, son vulnerables a suplantaciones de un dispositivo legítimo por parte de un actor malicioso, lo que puede permitir a un atacante ejecutar comandos arbitrarios remotamente This vulnerability allows remote attackers to execute arbitrary code on affected installations of Mitsubishi Electric MELSEC iQ-F. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of ACK packets. When generating ACK packets, the application uses a predictable sequence number. An attacker can leverage this vulnerability to execute arbitrary code in the context of the current process. • https://us-cert.cisa.gov/ics/advisories/icsa-20-245-01 • CWE-342: Predictable Exact Value from Previous Values •
