-------------------------------
[~bmarwell] [~Palak-137] hi! iam not discover a security-relevant issue.
your can check a project called "ysoserial". hacker can Deserialization of
Untrusted Data with Apache Commons Collections
and also , your can check a link:
[https://community.pega.com/knowledgebase/articles/security/85/java-deserialization]
in this link , we can find global security check with Deserialization
Vulnerability.
so if we block these classes in
shiro/lang/src/main/java/org/apache/shiro/lang/io/ClassResolvingObjectInputStream.java
resolveClass funtion
we can defender Deserialization Vulnerability.
thx
