CVE-2022-31767Network attack vector

Unauthenticated command execution via crafted request

Published Jun 24, 2022 · Updated Sep 16, 2024

Command injection in IBM CICS TX Standard and Advanced 11.1 allows remote attackers to execute arbitrary system commands via a crafted request. IBM has not disclosed the request handler, affected endpoint, parameter, or operation that passes attacker-controlled data to an OS command. No authentication or user interaction is required, and successful exploitation grants command execution with the affected service's privileges.
