[jira] [Commented] (SHIRO-808) security enhance

    [ https://issues.apache.org/jira/browse/SHIRO-808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17284767#comment-17284767 ] 

k4n5hao commented on SHIRO-808:
-------------------------------

[~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
