BIT-jenkins-2021-43859 — Denial of Service by injecting highly recursive collections or maps in XStream

Affected: Bitnami: jenkins

XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible. Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not possible.

GHSA-rmr5-cpv2-vgjf — Denial of Service by injecting highly recursive collections or maps in XStream

Affected: Maven: com.thoughtworks.xstream:xstream

### Impact The vulnerability may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream.

### Patches XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded.

### Workarounds The attack uses the hash code implementation for collections and maps to force an exponential calculation time due to highly recursive structures with in the collection or map. Following types of the Java runtime are affected in Java versions available in December 2021:

- java.util.HashMap - java.util.HashSet - java.util.Hashtable - java.util.LinkedHashMap - java.util.LinkedHashSet - java.util.Stack (older Java revisions only) - java.util.Vector (older Java revisions only) - Other third party collection implementations that use their element's hash code may also be affected

If your object graph does not use referenced elements at all, you may simply set the NO_REFERENCE mode: ```Java XStream xstream = new XStream(); xstream.setMode(XStream.NO_REFERENCES); ```

If your object graph contains neither a Hashtable, HashMap nor a HashSet (or one of the linked variants of it) then you can use the security framework to deny the usage of these types: ```Java XStream xstream = new XStream(); xstream.denyTypes(new Class[]{ java.util.HashMap.class, java.util.HashSet.cl…
