WSO2 Management Console XSS (CVE-2022-29548)
Description
The WSO2 Management Console contains a cross-site scripting (XSS) vulnerability (CVE-2022-29548) due to insufficient input sanitization. This flaw allows attackers to inject malicious scripts into web pages viewed by other users, potentially compromising user sessions and sensitive data. The vulnerability affects the administrative interface used to manage WSO2 products.
Remediation
1. Upgrade to the patched version of WSO2 software as specified in security advisory WSO2-2021-1603 (https://security.docs.wso2.com/en/latest/security-announcements/security-advisories/2022/WSO2-2021-1603/)
2. Review the security advisory for specific version numbers and patch details applicable to your WSO2 product
3. If immediate patching is not possible, implement the following temporary mitigations:
• Restrict access to the Management Console to trusted IP addresses only
• Implement Web Application Firewall (WAF) rules to filter malicious input patterns
• Enable Content Security Policy (CSP) headers to limit script execution
4. After patching, review access logs for any suspicious activity or exploitation attempts
5. Educate administrators to avoid clicking untrusted links while authenticated to the Management Console
