Associated Vulnerability

Title:多款ZOHO ManageEngine产品安全漏洞 (CVE-2022-47966)
Description:Multiple Zoho ManageEngine on-premise products, such as ServiceDesk Plus through 14003, allow remote code execution due to use of Apache Santuario xmlsec (aka XML Security for Java) 1.4.1, because the xmlsec XSLT features, by design in that version, make the application responsible for certain security protections, and the ManageEngine applications did not provide those protections. This affects Access Manager Plus before 4308, Active Directory 360 before 4310, ADAudit Plus before 7081, ADManager Plus before 7162, ADSelfService Plus before 6211, Analytics Plus before 5150, Application Control Plus before 10.1.2220.18, Asset Explorer before 6983, Browser Security Plus before 11.1.2238.6, Device Control Plus before 10.1.2220.18, Endpoint Central before 10.1.2228.11, Endpoint Central MSP before 10.1.2228.11, Endpoint DLP before 10.1.2137.6, Key Manager Plus before 6401, OS Deployer before 1.1.2243.1, PAM 360 before 5713, Password Manager Pro before 12124, Patch Manager Plus before 10.1.2220.18, Remote Access Plus before 10.1.2228.11, Remote Monitoring and Management (RMM) before 10.1.41. ServiceDesk Plus before 14004, ServiceDesk Plus MSP before 13001, SupportCenter Plus before 11026, and Vulnerability Manager Plus before 10.1.2220.18. Exploitation is only possible if SAML SSO has ever been configured for a product (for some products, exploitation requires that SAML SSO is currently active).

Description

POC for CVE-2022-47966 affecting multiple ManageEngine products

Readme

# CVE-2022-47966
POC for CVE-2022-47966 affecting the following ManageEngine products:
* Access Manager Plus
* Active Directory 360
* ADAudit Plus
* ADManager Plus
* ADSelfService Plus
* Analytics Plus
* Application Control Plus
* Asset Explorer
* Browser Security Plus
* Device Control Plus
* Endpoint Central
* Endpoint Central MSP
* Endpoint DLP
* Key Manager Plus
* OS Deployer
* PAM 360
* Password Manager Pro
* Patch Manager Plus
* Remote Access Plus
* Remote Monitoring and Management (RMM)
* ServiceDesk Plus
* ServiceDesk Plus MSP
* SupportCenter Plus
* Vulnerability Manager Plus

This specific POC only works on products utilizing Apache Santuario (xmlsec) <= 1.4.1 such as:
* ServiceDesk Plus
* Endpoint Central
* ADManager Plus
* ADSelfService Plus

Other products may perform additional checks on the SAML response. Modifying this POC to work on products that perform additional checks involves:
* Scanning the logs of the vulnerable product for stack traces or additional logs message indicating an invalid SAML response.
* Reverse engineering the vulnerable product and searching for the code that implements the checks.

## Summary
This POC abuses the pre-authentication remote code execution vulnerability to run a command with Java's Runtime.exec method.

## Usage
For Active Directory related products, such as ADManager, an issuer argument is required:
```plaintext
root@kali:~# python3 ./CVE-2022-47966.py --url https://10.0.40.90:8443/samlLogin/<guid> --issuer https://sts.windows.net/<guid>/ --command notepad.exe
```

For other products, a URL is all that is required:
```plaintext
root@kali:~# python3 ./CVE-2022-47966.py --url https://10.0.40.64:8080/SamlResponseServlet --command notepad.exe
```

## Mitigations
Update to the latest version of the affected product.
