Description

Title: Critical Vulnerability - Remote Code Execution (RCE) on Bean Money Platform

VRT: VRT-2024-003

CVSS: 9.8 (Critical)

Description: A critical vulnerability allowing remote code execution (RCE) has been identified on the Bean Money platform accessible via the URL https://app.bean.money. This vulnerability arises from inadequate input validation and sanitization, enabling malicious actors to execute arbitrary code on the server-side.

Impact: The impact of this vulnerability is severe, as it grants attackers the ability to execute arbitrary code on the server hosting the Bean Money platform. This could lead to complete compromise of the system, including unauthorized access to sensitive data, manipulation of financial transactions, and even full control over the Bean Money platform itself.

Proof of Concept:

  1. Craft a malicious payload containing executable code, such as a Python reverse shell.
  2. Send a request to the vulnerable endpoint, passing the crafted payload as a parameter, e.g., https://app.bean.money/vulnerable_endpoint?param=<malicious_payload>.
  3. Upon processing the request, the server fails to properly sanitize the input, leading to the execution of the malicious code on the server-side.
  4. The attacker gains remote access to the server, allowing them to perform arbitrary actions, exfiltrate data, or escalate their privileges.

Recommended Fix:

  1. Immediately patch the vulnerability by implementing strict input validation and sanitization measures on all user-supplied data.
  2. Conduct a comprehensive security audit of the entire Bean Money platform to identify and remediate any similar vulnerabilities.
  3. Enhance security awareness and training among developers to prevent similar vulnerabilities in future code changes.

Impact Explanation: The critical nature of this vulnerability lies in its potential to allow attackers to execute arbitrary code on the server-side, leading to complete compromise of the Bean Money platform. With remote code execution capabilities, attackers can manipulate financial data, steal sensitive information, and disrupt the platform's operations. It is imperative to address this vulnerability immediately to prevent catastrophic consequences and safeguard the integrity of the Bean Money platform.

Proof of concept

Proof of Concept**:

  1. Craft a malicious payload containing executable code, such as a Python reverse shell.
  2. Send a request to the vulnerable endpoint, passing the crafted payload as a parameter, e.g., https://app.bean.money/vulnerable_endpoint?param=<malicious_payload>.
  3. Upon processing the request, the server fails to properly sanitize the input, leading to the execution of the malicious code on the server-side.
  4. The attacker gains remote access to the server, allowing them to perform arbitrary actions, exfiltrate data, or escalate their privileges.

Immunefi Response

Thank you for submitting your vulnerability report to the Beanstalk bug bounty program. We appreciate your efforts and taking the time to report vulnerabilities to us. We have reviewed your submission, but unfortunately, we are closing the report for the following reasons:
  • The submission contains the output of an automated scanner without demonstrating that it is a valid issue.
  • The submission lacks the required information regarding the vulnerability's impact on the reported asset.

As per the bug bounty program's policy, we require all submissions to be accompanied by a Proof of Concept (PoC) that demonstrates the vulnerability's existence and impact. Since the submission doesn't provide any proof of the vulnerability's existence, we have decided to close it.

Please note that the project will receive a report of the closed submission and may choose to re-open it, but they are not obligated to do so.
