Description
IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to perform account takeover due to an open redirect vulnerability. The redirect address used during OAuth 2.0 sign-in is not sufficiently validated, which could allow authentication results to be sent to an attacker-controlled location.

AI Analysis

Impact

A remote authenticated attacker can cause the OAuth 2.0 sign‑in redirect address to be forwarded to an attacker‑controlled location, allowing credential theft and subsequent account takeover. The flaw is an open redirect vulnerability, classified as CWE‑601, that undermines authentication integrity.

Affected Systems

IBM API Connect versions 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 are affected. Upgrading to 10.0.8.13 or 12.1.1.3 removes the vulnerability.

Risk and Exploitability

The CVSS score of 8.7 indicates high severity. EPSS data is not available, making exploitation frequency uncertain, but the vulnerability requires only a legitimate authentication, which is likely in many deployments. Although not listed in the CISA KEV catalog, the potential for account takeover and the absence of an early warning suggest that the risk of exploitation is real and should be treated with high urgency.
