CVE-2024-4867: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in WSO2 WSO2 API Manager
The WSO2 API Manager developer portal accepts user-supplied input without enforcing expected validation constraints or proper output encoding. This deficiency allows a malicious actor to inject script content that is executed within the context of a user's browser. By leveraging this cross-site scripting vulnerability, a malicious actor can cause the browser to redirect to a malicious website, make changes to the UI of the web page, or retrieve information from the browser. However, session hijacking is not possible as all session-related sensitive cookies are protected by the httpOnly flag.
AI Analysis
Technical Summary
The WSO2 API Manager developer portal suffers from CWE-79: Improper Neutralization of Input During Web Page Generation, commonly known as cross-site scripting (XSS). This vulnerability exists because user-supplied input is not properly validated or encoded before being included in web pages. As a result, attackers can inject script content that executes in the context of other users' browsers. The impact includes potential redirection to malicious websites, alteration of the user interface, and unauthorized access to browser information. Session hijacking is not feasible due to the httpOnly flag on session cookies. The vulnerability affects multiple versions of WSO2 API Manager (3.2.0, 3.2.1, 4.0.0, 4.1.0). There is no vendor-provided patch or official remediation at this time.
Potential Impact
Successful exploitation allows attackers to execute arbitrary scripts in users' browsers when they access the developer portal, potentially leading to UI manipulation, redirection to malicious sites, or theft of browser-accessible information. However, session hijacking is prevented by the httpOnly flag on session cookies. The overall impact is rated medium severity with a CVSS score of 5.4.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution when interacting with the developer portal and avoid clicking on suspicious links or inputs. No vendor-provided mitigation or temporary fix is currently documented.
