Summary

CVE-2025-36072 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Ibm Webmethods Integration. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 27.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

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.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

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).

NVD 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.

Deeper analysisAI

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).
