CVE-2026-16340

Summary

The flaw is an out-of-bounds write in the RFC2047 encoded-word parser, allowing remote attackers to execute arbitrary code. This matters because it provides a critical vulnerability that can be exploited to gain full control over the affected IBM DataPower Gateway instances.

Exploitability

Exploitation is relatively straightforward given the remote code execution capability, requiring only the ability to send crafted input to the affected parser.

Blast radius

If exploited, the impact could be severe, as it allows attackers to execute arbitrary code on the gateway, potentially leading to data theft, service disruption, or complete compromise of the system.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to IBM DataPower Gateway 10.5.0.23 or later, 10.6.7 or later, or 11.0.0.3 or later.
