Descriptions

Scala 2.13.x before 2.13.9 has a Java deserialization chain in its JAR file. On its own, it cannot be exploited. There is only a risk in conjunction with Java object deserialization within an application. In such situations, it allows attackers to erase contents of arbitrary files, make network connections, or possibly run arbitrary code (specifically, Function0 functions) via a gadget chain.

Scala versiones 2.13.x anteriores a 2.13.9 tiene una cadena de deserialización de Java en su archivo JAR. Por sí sola, no puede ser explotada. Sólo existe un riesgo en conjunto con la deserialización de objetos Java dentro de una aplicación. En tales situaciones, permite a los atacantes borrar el contenido de archivos arbitrarios, hacer conexiones de red, o posiblemente ejecutar código arbitrario (específicamente, funciones Function0) a través de una cadena de gadgets.

A flaw was found in Scala's LazyList that permits code execution during deserialization. This issue could allow an attacker to craft a LazyList containing a malicious Function0 call to execute arbitrary code on a server that deserializes untrusted data.
