CVE-2021-29508

Estado: ModificadaCrítica (9.1)—

Debido a la forma en que Wire maneja la información de tipo en su formato de serialización, las cargas útiles maliciosas pueden ser pasadas a un deserializador. por ejemplo, utilizando un sustituto en el extremo del remitente, un atacante puede pasar información sobre un tipo diferente para el extremo receptor. Y al hacerlo, permite que el serializador cree cualquier tipo en el extremo de deserialización. Este es el mismo problema que se presenta para .NET BinaryFormatter https://docs.microsoft.com/en-us/visualstudio/code-quality/ca2300?view=vs-2019. Esto también se aplica a la bifurcación de Wire

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
