CVE-2022-36944

CRITICAL

Scala < 2.13.9 - Insecure Deserialization

Title source: rule
STIX 2.1

Description

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.
