KRCERT issued a vulnerability advisory for Korean security and keyboard-protection products AnySign4PC, TouchEn nxKey, and CrossEX. The advisory says AnySign4PC can expose internal information through a vulnerability, TouchEn nxKey is affected by buffer-overflow and remote-code-execution issues, and CrossEX can allow arbitrary license issuance. While the source does not attribute exploitation to a named threat actor, the affected software is security-sensitive and commonly deployed in Korean environments, making rapid patching important for intrusion prevention. Administrators should update or replace vulnerable installations through the vendor links, remove outdated client software where possible, and monitor for suspicious activity involving these products.
