CVE-2021-27085
HIGH ⌖ ON CISA KEV · EXPLOITEDMicrosoft Internet Explorer had a remote code execution vulnerability that was actively exploited in the wild.
Internet Explorer contained an unspecified vulnerability allowing remote code execution, which was listed in CISA's KEV catalog as actively exploited. DIB organizations must care because unpatched legacy browsers can serve as an entry point for attackers to execute arbitrary code on systems, violating CMMC/NIST 800-171 requirements for patch management and system hardening. Organizations should immediately disable or patch IE and ensure all legacy software is updated or removed to prevent exploitation.
Shame score — A known remote code execution vulnerability in a widely used product was actively exploited in the wild, indicating negligent patching and avoidable exposure.
