CVE-2024-57080 - Prototype Pollution in vxe-table v4.8.10 Leading to Denial of Service Attacks

CVE-2024-57080 marks a critical vulnerability in the vxe-table package version 4.8.10, resulting from a prototype pollution issue in the lib.install function. Attackers can exploit this vulnerability to cause a Denial of Service (DoS) by supplying a maliciously crafted payload. This article delves deep into the nature of the exploit, important code snippets, and the necessary actions to mitigate the risk posed by the CVE-2024-57080 vulnerability.

Exploit Details

Prototype pollution is a severe security issue in JavaScript applications that allows an attacker to manipulate an application's prototype. In turn, the attacker gains the ability to alter the default functionality and behavior of objects created in the application.

In the case of vxe-table v4.8.10, the lib.install function fails to properly validate and sanitize user input, allowing an attacker to inject a polluted payload into the prototype chain. When the application processes this payload, it leads to undesirable outcomes, including system crashes and disrupted service.

Code Snippet

Consider the following simplified code snippet from the lib.install function in vxe-table v4.8.10:

function install(Vue) {
  const methods = {};
  Object.keys(_methods).forEach(name => {
    methods[name] = function (...args) {
        const self = ChunkIncluded.argsToObject(_methods[name], args);
        return _methods[name].apply(this || self, args);
    };
  });

  // ... other code ...
  function ChunkIncluded(args) {
    // ... function implementation ...
  }

}

In this code snippet, the lib.install function iterates through the _methods object and assigns its properties to the methods object. During this process, no sanitization occurs to prevent prototype pollution.

To exploit this vulnerability, an attacker can craft a polluted payload such as this

{
  "constructor.prototype.myPayload": "malicious_data"
}

When the polluted payload is processed through the lib.install function, it leaves the application's prototype polluted with malicious_data.

Mitigation

To address this vulnerability, developers using the vxe-table package must update their package to a patched version that resolves the prototype pollution issue. As required, developers should consider employing input validation and sanitization techniques throughout the application to prevent such vulnerabilities in the future.

In conclusion, the CVE-2024-57080 vulnerability in vxe-table v4.8.10 presents a significant risk due to its potential for Denial of Service attacks. Developers must take immediate action to update their version of the vxe-table package and apply additional measures to ensure their applications remain secure against prototype pollution exploits.
