CVE-2025-2516

The use of a weak cryptographic key pair in the signature verification process in WPS Office (Kingsoft) on Windows allows an attacker who successfully recovered the private key to sign components. As older versions of WPS Office did not validate the update server's certificate, an Adversary-In-The-Middle attack was possible allowing updates to be hijacked.

Summary		(es) El uso de un par de claves criptográficas débiles en el proceso de verificación de firmas de WPS Office (Kingsoft) en Windows permite que un atacante que haya recuperado la clave privada firme componentes. Dado que las versiones anteriores de WPS Office no validaban el certificado del servidor de actualizaciones, era posible un ataque de intermediario que permitiera el secuestro de actualizaciones.
