CVE-2025-54947 Apache StreamPark vulnerability security critical severity hard-coded key encryption vulnerability CVE database information disclosure unauthorized access

Summary

CVE-2025-54947 is a critical security vulnerability affecting Apache StreamPark versions 2.0.0 through 2.1.6. It stems from the use of a hard-coded encryption key, which can be exploited to decrypt sensitive data or forge encrypted information, leading to information disclosure and unauthorized system access.

Technical Details

CVE-2025-54947 arises from the implementation of a fixed, immutable encryption key within Apache StreamPark versions 2.0.0 to 2.1.6. This hard-coded key is used for encrypting sensitive data within the application. Because the key is static and embedded within the application's code, it becomes susceptible to discovery through reverse engineering or static code analysis. An attacker who successfully retrieves this key can then decrypt any data encrypted using it, potentially exposing sensitive information such as user credentials, configuration settings, or other confidential data. Furthermore, the attacker could use the key to forge encrypted data, potentially gaining unauthorized access to the system or manipulating application behavior. The vulnerability lies in the lack of proper key management practices, specifically the failure to dynamically generate or securely configure the encryption key.

The impact is amplified by the fact that the same key is likely used across multiple installations of the affected StreamPark versions, meaning that a single key compromise could affect a large number of systems. This vulnerability highlights the importance of secure key management practices in software development.

Affected Products and Versions

This vulnerability affects the following product and versions:

  • Apache StreamPark: Versions 2.0.0 through 2.1.6

Impact Assessment

Successful exploitation of CVE-2025-54947 can have severe consequences:

  • Information Disclosure: Sensitive data encrypted using the hard-coded key can be decrypted, leading to the exposure of confidential information.
  • Unauthorized System Access: Attackers can forge encrypted data to gain unauthorized access to the system or manipulate application behavior.
  • Data Integrity Compromise: The ability to forge encrypted data can lead to data corruption and loss of data integrity.
  • Reputational Damage: A successful attack can damage the reputation of organizations using the affected Apache StreamPark versions.

Remediation

Immediate Actions

  • Upgrade to Version 2.1.7: The primary and recommended solution is to upgrade Apache StreamPark to version 2.1.7 or later. This version addresses the vulnerability by implementing secure key management practices.
  • Review Security Logs: Monitor security logs for any suspicious activity that may indicate exploitation attempts.

Long-term Solutions

  • Implement Secure Key Management: Ensure that all applications use dynamically generated or securely configured encryption keys. Avoid hard-coding keys directly into the application code.
  • Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities.
  • Vulnerability Scanning: Implement automated vulnerability scanning tools to proactively identify security weaknesses in your systems.
