Detection & IOCsextracted from sources · hover to see the quote

  • →Vulnerability affects IBM API Connect versions 10.0.8.0 through 10.0.8.5 and 10.0.11.0; detect exposed instances by identifying these version strings in network banners or API responses ↗
  • →Monitor for unauthenticated access attempts to IBM API Connect Developer Portal endpoints, particularly self-service sign-up flows, which are the attack surface for this bypass ↗
  • →Alert on successful authentication events to IBM API Connect that are not preceded by a valid credential submission — indicative of authentication mechanism bypass in low-complexity, no-user-interaction attacks ↗
  • ·Disabling self-service sign-up on the Developer Portal is a recommended mitigation for those unable to patch immediately, but it only minimises (not eliminates) exposure ↗
  • ·The vulnerability is exploitable remotely with no authentication and no user interaction required, making internet-exposed instances at critical risk ↗
