Seven Middleware Challenges You Must Overcome Before Your Cloud Migration

Addressing Two IBM App Connect Enterprise Vulnerabilities

IBM®App Connect Enterprise (ACE) is a powerful tool for seamless integration across your business environment, connecting disparate applications and data flows. However, like any complex system, security vulnerabilities can pose significant challenges. Recently, IBM addressed critical IBM App Connect Enterprise Vulnerabilities involving OpenSSL, which could potentially be exploited by remote attackers to cause denial-of-service (DoS) issues.

Understanding the Vulnerabilities

Two significant IBM App Connect Enterprise vulnerabilities were identified and fixed:

  1. CVE-2024-6119: This vulnerability in OpenSSL is due to improper certificate name checks performed during TLS client operations. Exploitation by sending a specially crafted request could lead to the reading of invalid memory addresses, resulting in an abnormal application termination. This vulnerability has been given a CVSS score of 7.5, highlighting its severity. For more technical details, refer to the NIST listing for CVE-2024-6119 and Common Weakness Enumeration (CWE-843)
  2. CVE-2024-5535: This issue involves a buffer over-read flaw within the SSL_select_next_proto API when processing an empty supported client protocols buffer. Exploiting this vulnerability could result in a crash or inadvertent exposure of memory contents. Although rated with a CVSS score of 3.7, which is lower than the previous vulnerability, it still poses a risk that organizations should address. More about buffer over-reads can be found here and additional information on CVE-2024-5535 can be found at the NIST site here.

Affected Versions

These vulnerabilities impact specific versions of IBM App Connect Enterprise:

  • IBM ACE 12.0.1.0 through 12.0.12.7
  • IBM ACE 13.0.1.0

Remediation and Fixes

The APAR IT47083 addresses both vulnerabilities in these releases. To mitigate these vulnerabilities, IBM has released the following fixes:
