Impact
The vulnerability is an out-of-bounds read in the request handling code of IBM DataPower Gateway, identified by CWE‑125. An attacker can trigger this flaw by sending a specially crafted packet or message over the network, leading the gateway to read unintended memory and crash. The result is a reboot or hang of the device, causing a denial of service that affects all clients and downstream services relying on that appliance.
Affected Systems
Affected products include IBM DataPower Gateway versions 10.5.0.0 through 10.5.0.22, 10.6.0.0 through 10.6.0.10, 10.6.1 through 10.6.6, and 11.0.0.0 through 11.0.0.2. The fix is available in release 10.6.0.11, 10.6.1.0, 10.6.6.1, 11.0.0.3, and 10.5.0.23, and later.
Risk and Exploitability
The CVSS score of 7.5 indicates high impact and moderate impact on availability. The EPSS score is not available, so the current probability of exploitation cannot be quantified. The vulnerability is not listed in CISA KEV, suggesting no known active exploits at the time of this analysis. Based on the description, the likely attack vector is remote network access; an unauthenticated attacker who can reach the gateway is sufficient to trigger the DoS.
