Both CVEs describe a vulnerability in the Jackson library, and this vulnerability allows attackers to exploit deserialization to achieve Remote Code Execution (RCE) on a server. This is accomplished through enabling "Default Typing" in Jackson ...

A cheat sheet for pentesters and researchers about deserialization vulnerabilities in various Java (JVM) serialization libraries.

September 13, 2017 - The lab contains code samples that help you understand deserialization vulnerabilities and how gadget chains exploit them. The goal is to provide a better understanding so that you can develop new payloads and/or better design your environments. There is also a vulnerable testing application (VulnerableHTTPServer.java...

Jenkins CLI RMI Java Deserialization RCE (CVE-2015-8103)

This project contains a Java deserialization vulnerability that is exploitable with some ysoserial payloads, but also contains a custom class that can be leveraged to get command execution upon deserialization.

A proof-of-concept tool for generating payloads that exploit unsafe Java object deserialization. - frohoff/ysoserial

This tool builds upon the proof-of-concept ysoserial by Chris Frohoff (https://github.com/frohoff/ysoserial) and exploits the Java Deserialization vulnerability, using Metasploit Framework tools to generate a malicious binary and an embedded ...

Java Deserialization Scanner uses custom payloads generated with a modified version of "ysoserial", tool created by frohoff and gebl, to detect Java deserialization vulnerabilities. The original tool (https://github.com/frohoff/ysoserial) generate payloads for the execution of commands on the system, using the Runtime.exec function.

July 2, 2019 - We can use CodeQL, the query technology of LGTM, to find such deserialization vulnerabilities. In order to do this we must find the places where deserialization happens, and furthermore we need to check that untrusted data can actually reach ...

Thorugh the getConnection method, DriverManagerConnectionSource downloads the inject.sql file. The inject.sql file leverage a vulnerability in the H2 Java library which, through the command CREATE ALIAS, permits to execute Java code.

Here there are practical examples of the - deserialization of untrusted data - vulnerability. These pocs use the ysoserial tool to generate exploits. ... cd MinimalExample java -jar ../ysoserial-master-v0.0.5-gb617b7b-16.jar CommonsCollections6 "/tmp/exploit.sh">payload.ser cp ./exploit.sh /tmp chmod +x /tmp/exploit.sh javac Employee.java javac DeSerializingObject.java java -classpath .:apache-collections-commons-collections-3.1.jar DeSerializingObject

CVE-2023-40195: Apache Airflow Spark Provider Deserialization Vulnerability RCE (Java)

Java object deserialization: The Java ObjectInputStream library is vulnerable to insecure deserialization if not used carefully.

A cheat sheet for pentesters and researchers about deserialization vulnerabilities in various Java (JVM) serialization libraries.

2. XStream with fromXML method (xstream version <= v1.4.6 is vulnerable to the serialization issue) ... If the captured traffic data includes the following patterns, it may suggest that the data was sent in Java serialization streams: ... If there are data members of an object that should never be controlled by end users during deserialization or exposed to users during serialization, they should be declared as the transient keyword (section Protecting Sensitive Information).

Finally, I have a functioning webapp with a version of Spring which is less than a year old and has an indirect vulnerability due to Jackson v2.9.9. Next weekend I'll be reading up on how to properly exploit this and coding up the actual PoC. I started my day reading up on something called Magic Methods. There's a lot to catch up on... and I don't particularly enjoy Java. They are a kind of method that classes can implement in order to control how they get serialized/deserialized.
