IBM API Connect flaw lets unauthenticated remote attackers run operating system commands
IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 contain a critical OS command injection flaw. A remote attacker could execute arbitrary code. Review IBM's support pages and apply the vendor's guidance promptly.
In plain terms
IBM API Connect is a platform that organisations use to publish, secure and manage their APIs, the interfaces that let applications talk to each other. A flaw in certain versions means the software does not properly clean up input before passing it to the underlying operating system. This is called command injection: an attacker can slip their own instructions into data the system later runs as a command.
If exploited, an attacker over the network could run code on the server hosting API Connect without needing a login or any help from a user. Organisations running the affected 10.0.8 or 12.1 releases, especially where the platform is reachable from untrusted networks, should treat this as urgent.
Technical analysis
The weakness is CWE-78, improper neutralization of special elements used in an OS command. The official description states that a remote attacker could execute arbitrary code as a result. The sources do not identify the specific component, endpoint or code path in API Connect that passes attacker-influenced input to an operating system command.
The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. The attack is network-reachable, has low complexity, requires no privileges and needs no user interaction. Scope is unchanged, so the scored impact is limited to the vulnerable component. That component still suffers high loss of confidentiality, integrity and availability.
