December 20, 2021Rewterz Threat Advisory – CVE-2021-42278 – Microsoft Windows privilege escalation
December 21, 2021
Severity
High
Analysis Summary
CVE-2021-20608
If an attacker tampers with a program file in a Mitsubishi Electric PLC by sending malicious crafted packets to the PLC, reading the program file into GX Works2, the engineering software incorrectly handles a length field that is inconsistent with the actual length of the associated data, which could result in a denial-of-service condition in the software.
CVE-2021-20607
When a valid user opens a malicious project file specially crafted by an attacker, the product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
CVE-2021-20606
When a valid user opens a malicious project file specially crafted by an attacker, the software reads data outside of the intended buffer, allowing an attacker to potentially cause a denial-of-service condition in the software.
