Summary
jooby-pac4j: deserialization of untrusted data
Details

Impact

Versions after 2.x and before 3.x of io.jooby:jooby-pac4j can cause deserialization of untrusted data

Patches

  • 2.17.0 (2.x)
  • 3.7.0 (3.x)

Workarounds

  • Not using io.jooby:jooby-pac4j until it gets patches.
  • Check what values you put/save on session

References

Version 2.x:

https://github.com/jooby-project/jooby/blob/v2.x/modules/jooby-pac4j/src/main/java/io/jooby/internal/pac4j/SessionStoreImpl.java#L39-L45

Version 3.x: https://github.com/jooby-project/jooby/blob/v3.6.1/modules/jooby-pac4j/src/main/java/io/jooby/internal/pac4j/SessionStoreImpl.java#L77-L84

Cause

In module pac4j io.jooby.internal.pac4j.SessionStoreImpl#get , it is used to handle sessions , and trying to get key value. In strToObject function ,it's trying to deserialize value when value starts with "b64~" , which might cause deserialization of untrusted data.

Here's a small demo using SessionStoreImpl#get to handle sessions ,and user can pass parameters.
