CVE-2022-36944: Critical severity ibm engineering requirements management doors web access vulnerability

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 LazyList 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 could allow a remote authenticated attacker to execute arbitrary code on the system, caused by an unsafe deserialization in LazyList. By sending specially-crafted request using gadget chain, an attacker could exploit this vulnerability to execute arbitrary code, erase contents of arbitrary files or make network connections.
