The openssl_encrypt library suffers from insufficient data authenticity verification, which could permit unauthorized processing of tampered inputs.

This vulnerability involves insufficient verification of data authenticity (CWE-345). An unauthenticated attacker can leverage this weakness to bypass security checks, as the library fails to properly validate the integrity of incoming data streams.

The inability to verify data authenticity can lead to the successful injection of malicious payloads or the compromise of system integrity. With a CVSS score of 7.5, this vulnerability represents a high risk for organizations, as it could lead to unauthorized access or the corruption of critical business processes that rely on the library for secure communication.

Immediate Action: Update the jahlives openssl_encrypt package to version 1.4.0 or later to enforce proper data authenticity verification.

Proactive Monitoring: Monitor for anomalous data processing patterns or attempts to submit malformed packets that might indicate an attempt to bypass validation.

Compensating Controls: Use a Web Application Firewall (WAF) or an API gateway to inspect and validate data structures before they reach the vulnerable library components.

Public Exploit Available: false

Maintaining data integrity is paramount for secure operations. Administrators must deploy the 1.4.0 update to ensure that all data is properly authenticated and to prevent potential exploitation of this integrity flaw.
