Impact
A null pointer dereference was discovered in IBM DataPower Gateway firmware. The flaw enables an unauthenticated remote attacker to trigger a segmentation fault that brings the gateway process to a halt, causing the device to become non‑responsive. This is a classic null pointer reference problem classified as CWE‑476. The impact is limited to availability and does not compromise data confidentiality or integrity.
Affected Systems
IBM reported the defect for several DataPower Gateway releases: 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, and 11.0.0.0 through 11.0.0.2. The vulnerability is fixed in firmware releases 10.6.1 (10.6CD) and newer, 10.6.0.11 and newer, 11.0.0.2 and newer, and 10.5.0.23 and newer. Devices running earlier revisions remain vulnerable. The affected vendor is IBM and the product is DataPower Gateway.
Risk and Exploitability
The CVSS score of 7.5 indicates high severity with medium‑to‑high exploitability. No EPSS data is available, and the flaw is not listed in the CISA KEV catalog. Based on the description, the attack vector is remote, requiring network access to the device’s management or service interfaces. A remote attacker could repeatedly force the gateway into a DoS state, which remains a valuable tactic for disruptive attacks.
