CVE-2015-7501 is an insecure deserialization vulnerability affecting multiple Red Hat middleware products that include vulnerable versions of the Apache Commons Collections library. The flaw arises when attacker-controlled serialized Java objects are deserialized by an exposed application component and a Commons Collections gadget chain is available, allowing execution of arbitrary commands during deserialization. Affected Red Hat offerings include JBoss A-MQ, BPM Suite, BRMS, Data Grid, Data Virtualization, Enterprise Application Platform, Fuse, Fuse Service Works, JBoss ON, Portal, SOA Platform, Web Server, OpenShift/xPAAS, and Subscription Asset Manager across the versions identified for this CVE. The issue is fundamentally tied to deserialization of untrusted data in Java applications using the vulnerable library and can be triggered remotely where a reachable deserialization path exists.

This repository is a comprehensive Java deserialization exploitation lab, containing multiple proof-of-concept (PoC) exploits and a vulnerable HTTP server for testing. The code samples demonstrate how to craft malicious serialized Java objects (both binary and XML) that exploit gadget chains in Apache Commons Collections (<= 3.2.1) and Java's own classes to achieve arbitrary code execution upon deserialization. Key files include: - `VulnerableHTTPServer.java`: A test server that accepts serialized objects via HTTP POST, cookies, or XML, and deserializes them, simulating real-world vulnerable applications. - `ExampleCommonsCollections1.java`, `ExampleTransformersWithLazyMap.java`, `ReverseShellCommonsCollectionsHashMap.java`, and `reverseShellMultiplatformCommonsCollections.xml`: These files generate payloads that, when deserialized, execute arbitrary commands or establish a reverse shell by loading a remote class from an attacker-controlled server. - `DnsWithCommonsCollections.java`: Generates a payload that triggers an HTTP/DNS request to an attacker-controlled domain, useful for blind exploitation validation. - `ExploitGadgetExample1.java`, `ForgottenClass.java`, and `SomeInvocationHandler.java`: Demonstrate custom gadget chains and the use of Java reflection and proxies to hijack execution flow during deserialization. - `TestSerialize.java` and `TestDeserialize.java`: Simple serialization/deserialization demos. The repository targets Java applications that deserialize untrusted data, especially those with vulnerable versions of Apache Commons Collections in the classpath. It includes PoCs for CVE-2017-7504 and CVE-2017-12149 (affecting JBoss products), and demonstrates both local and remote (network) attack vectors. The payloads can be delivered via HTTP POST, cookies, or XML, and can result in arbitrary command execution or reverse shells. Several endpoints and file paths are fingerprintable, including remote JAR URLs and files created on the target system as a result of exploitation.
