CVE-2025-58137 Apache Fineract vulnerability security high severity authorization bypass user-controlled key CVE database

Summary

CVE-2025-58137 describes a high-severity authorization bypass vulnerability affecting Apache Fineract. This vulnerability allows an attacker to bypass authorization checks by manipulating user-controlled keys, potentially gaining unauthorized access to sensitive data or functionalities within the Fineract system.

The vulnerability exists in Apache Fineract versions up to 1.11.0 and is resolved in version 1.12.1. Users are strongly encouraged to upgrade to version 1.13.0, the latest release, to mitigate this risk.

Technical Details

CVE-2025-58137 is an authorization bypass vulnerability stemming from the improper handling of user-controlled keys within the Apache Fineract application. Specifically, the application fails to adequately validate or sanitize keys provided by users, allowing an attacker to craft malicious keys that bypass authorization checks.

This vulnerability arises because the application relies on user-supplied data to determine access rights without proper validation. An attacker can exploit this by injecting specially crafted keys that are interpreted by the application as granting elevated privileges or bypassing access controls altogether. The exact mechanism of key manipulation will depend on the specific implementation details of the affected Fineract version, but it generally involves exploiting weaknesses in how the application parses, validates, or uses these keys.

Successful exploitation of this vulnerability could allow an attacker to perform actions they are not authorized to perform, such as accessing sensitive data, modifying system configurations, or executing arbitrary code. The impact of this vulnerability is significant due to the potential for complete compromise of the Fineract system.

Affected Products and Versions

  • Apache Fineract versions up to 1.11.0

Impact Assessment

Successful exploitation of CVE-2025-58137 can have severe consequences for organizations using Apache Fineract. An attacker who successfully bypasses authorization checks can gain unauthorized access to sensitive financial data, potentially leading to financial losses, reputational damage, and regulatory penalties.

  • Data breach risk: Unauthorized access to sensitive financial data, including customer accounts, transaction history, and personal information.
  • System compromise: Ability to modify system configurations, create or delete user accounts, and potentially execute arbitrary code on the server.
  • Financial loss: Fraudulent transactions, theft of funds, and other financial crimes.
  • Reputational damage: Loss of customer trust and damage to the organization's reputation.
  • Regulatory penalties: Fines and other penalties for non-compliance with data protection regulations.

Remediation

Immediate Actions

  • Upgrade Apache Fineract: The most effective remediation is to upgrade to Apache Fineract version 1.12.1 or, preferably, version 1.13.0, which contains the necessary security fixes.
  • Review Access Controls: Carefully review and strengthen access control policies to minimize the potential impact of a successful exploit.
  • Monitor System Logs: Implement robust monitoring of system logs to detect any suspicious activity that may indicate an attempted or successful exploitation of this vulnerability.

Long-term Solutions

  • Implement Input Validation: Implement robust input validation and sanitization techniques to prevent the injection of malicious keys.
  • Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities in the Fineract system.
  • Stay Updated: Subscribe to security advisories from Apache and other relevant sources to stay informed about the latest security threats and vulnerabilities.

Detection & Scanning

Detecting CVE-2025-58137 requires careful analysis of system logs and network traffic for suspicious activity related to user-controlled keys. Look for patterns of unauthorized access attempts or unusual key values being passed to the Fineract application.

Vulnerability scanners can also be used to identify vulnerable versions of Apache Fineract. However, these scanners may not be able to detect the specific vulnerability without proper configuration and knowledge of the application's internal workings.
