KR-CERT advised organizations and end users to update YettieSoft VestCert and MLSoft TCO!stream after the vendors released fixes for remote code execution vulnerabilities in the financial security products. The advisory warns that attackers could exploit the vulnerable software but does not provide exploitation details, malware, actor attribution, or IOCs. Service operators are directed to replace affected deployments through the vendors, while users should remove vulnerable VestCert versions, reinstall patched software from financial sites, and rely on TCO!stream auto-update through service operators.
