Description

IBM webMethods Integration 10.11 through 10.11_Core_Fix22, 10.15 through 10.15_Core_Fix22, and 11.1 through 11.1_Core_Fix6 IBM webMethods Integration allow an authenticated user to execute arbitrary code on the system, caused by the deserialization of untrusted object graphs data.

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match
prevent

Directly requires timely patching and remediation of the deserialization flaw as specified in IBM's security advisory to prevent arbitrary code execution.

SI-10 Information Input Validation good match
prevent

Mandates validation of untrusted inputs prior to deserialization to block malicious object graphs from being processed.

SI-16 Memory Protection partial match
prevent

Provides memory protections such as DEP and ASLR to mitigate the impact of arbitrary code execution resulting from unsafe deserialization.

Security SummaryAI

CVE-2025-36072 affects IBM webMethods Integration in versions 10.11 through 10.11_Core_Fix22, 10.15 through 10.15_Core_Fix22, and 11.1 through 11.1_Core_Fix6. The vulnerability stems from the deserialization of untrusted object graphs data, enabling an authenticated user to execute arbitrary code on the system. It is classified under CWE-502 (Deserialization of Untrusted Data) with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

An attacker requires low-privileged authenticated access (PR:L) to exploit this remotely over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation allows high-impact compromise of confidentiality, integrity, and availability (C:H/I:H/A:H), resulting in arbitrary code execution on the targeted system within the unchanged security scope (S:U).

Why these techniques?

Deserialization vulnerability in network-accessible IBM webMethods Integration Server enables remote code execution by low-privileged authenticated users, directly facilitating T1190 (Exploit Public-Facing Application) and T1068 (Exploitation for Privilege Escalation).
