Microsoft IME Japanese Privilege Escalation Vulnerability (CVE-2014-4077)
Severity: high · Patch status: patched · Since 2022-05-25 · CVE-2014-4077
Microsoft Input Method Editor (IME) Japanese is a keyboard with Japanese characters that can be enabled on Windows systems as it is included by default (with the default set as disabled). IME Japanese contains an unspecified vulnerability when IMJPDCT.EXE (IME for Japanese) is installed which allows attackers to bypass a sandbox and perform privilege escalation. CISA added CVE-2014-4077 to its Known Exploited Vulnerabilities catalog on May 25, 2022, which means attackers are exploiting it in the wild.
