Executive brief
IBM App Connect Enterprise, a platform used to integrate various business applications and data, is vulnerable to a security flaw that could allow an attacker to take control of the system. By sending specially crafted data, a remote attacker on the same local network could execute unauthorized commands, potentially leading to data theft, service disruption, or full system compromise. Organizations should apply the available security updates immediately to protect their integration environments.
Technical details
IBM App Connect Enterprise is vulnerable to OS command injection (CWE-78) due to the improper neutralization of Carriage Return/Line Feed (CRLF) characters. An unauthenticated attacker located on the adjacent network can exploit this flaw by submitting malicious input that includes these special characters to manipulate underlying system commands. Successful exploitation allows for arbitrary command execution with the privileges of the application. The vulnerability is addressed in IBM App Connect Enterprise v13 Fix Pack 13.0.8.0 and v12 Fix Pack 12.0.12.28.
