https://notcve.org/view.php?id=CVE-2020-8165
A deserialization of untrusted data vulnernerability exists in rails < 5.2.4.3, rails < 6.0.3.1 that can allow an attacker to unmarshal user-provided objects in MemCacheStore and RedisCacheStore potentially resulting in an RCE. Se presenta una vulnerabilidad de deserialización de datos no confiables en rails versiones anteriores a 5.2.4.3, rails versiones anteriores a 6.0.3.1, que puede permitir a un atacante desarmar los objetos proporcionados por el usuario en MemCacheStore y RedisCacheStore, lo que podría generar un RCE A flaw was found in rubygem-activesupport. An untrusted user input can be written to the cache store using the `raw: true` parameter which can lead to the result being evaluated as a marshaled object instead of plain text.
