Loading vulnerability…
CVE-2022-34169 is an integer-truncation vulnerability in the Apache Xalan Java XSLT library. When Xalan-J processes a malicious XSLT stylesheet, the flaw can corrupt Java class files generated by its internal XSLTC compiler, potentially enabling execution of arbitrary Java bytecode. Java runtimes, including OpenJDK distributions, may contain repackaged Xalan copies and can therefore be affected.

This repository is a Proof-of-Concept (PoC) exploit for CVE-2022-34169, a remote code execution vulnerability in Apache Xalan-J. The exploit leverages a constant pool integer truncation bug to craft a malicious XSLT file that, when processed by a vulnerable Xalan-J instance, results in arbitrary code execution. The main exploit logic is implemented in Python (exploit/CVE-2022-34169.py), which generates the payload and crafts the XSLT file. Supporting Java code (in exploit/xalancve) is used to generate and analyze Java class files and payloads. The repository includes Dockerfiles and a docker-compose.yml to set up both the exploit builder and a vulnerable server environment. The exploit is triggered by uploading the generated XSLT file to the target's /upload endpoint (default: http://localhost:8080/upload). By default, the payload writes 'pwned' to /tmp/pwned on the target, but it can be customized for arbitrary command execution. The structure is modular, with clear separation between exploit generation, payload definition, and server setup, making it a flexible PoC for research and demonstration purposes.
This repository is an automated payload generator for exploiting CVE-2022-34169, a vulnerability in the Xalan XSLT processor bundled with Oracle JDK (versions 6u0 through 8u301). The tool is written in Java and consists of two main source files: GenerateJdk.java and Util.java. The core functionality is to generate a version-specific malicious XSLT file (select.xslt) that, when processed by a vulnerable JDK/Xalan instance, can execute arbitrary system commands. The process involves analyzing the constant pool and structure of the compiled select.class file and adjusting the XSLT payload accordingly to match the quirks of different JDK versions. The README provides detailed instructions and a table mapping JDK versions to payload types. The repository does not contain a direct exploit against a remote target but provides the means to generate payloads for use in attacks where the attacker can supply XSLT to a vulnerable Java application. The main fingerprintable endpoints are the generated select.xslt file and the input 1.xml file. The attack vector is both local (if the attacker can place files on the system) and network (if the vulnerable application processes attacker-supplied XSLT over the network).
