Security Bulletin
Summary
There are multiple vulnerabilities in components of IBM i Modernization Engine for Lifecycle Integration as described in the Vulnerability Details section. HTTP Proxy bypass using IPv6 Zone IDs can improperly treat an IPv6 zone ID as a hostname component (CVE-2025-22870). Spring Framework DataBinder can bypass the disallowedFields checks (CVE-2025-22233). These components are used in IBM i Modernization Engine for Lifecycle Integration for infrastructure support in the platform. This bulletin identifies the steps to take to address the vulnerabilities as described in the remediation/fixes section.
Vulnerability Details
CVEID: CVE-2025-22870
DESCRIPTION: Matching of hosts against proxy patterns can improperly treat an IPv6 zone ID as a hostname component. For example, when the NO_PROXY environment variable is set to "*.example.com", a request to "[::1%25.example.com]:80` will incorrectly match and not be proxied.
CWE: CWE-115: Misinterpretation of Input
CVSS Source: CISA ADP
CVSS Base score: 4.4
CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L)
CVEID: CVE-2025-22233
DESCRIPTION: CVE-2024-38820 ensured Locale-independent, lowercase conversion for both the configured disallowedFields patterns and for request parameter names. However, there are still cases where it is possible to bypass the disallowedFields checks.
Affected Spring Products and Versions
Spring Framework:
* 6.2.0 - 6.2.6
* 6.1.0 - 6.1.19
* 6.0.0 - 6.0.27
* 5.3.0 - 5.3.42
* Older, unsupported versions are also affected
Mitigation
Users of affected versions should upgrade to the corresponding fixed version.
Affected version(s)Fix Version Availability 6.2.x
6.2.7
OSS6.1.x
6.1.20
OSS6.0.x
6.0.28
Commercial https://enterprise.spring.io/ 5.3.x
5.3.43
Commercial https://enterprise.spring.io/
No further mitigation steps are necessary.
Generally, we recommend using a dedicated model object with properties only for data binding, or using constructor binding since constructor arguments explicitly declare what to bind together with turning off setter binding through the declarativeBinding flag. See the Model Design section in the reference documentation.
For setting binding, prefer the use of allowedFields (an explicit list) over disallowedFields.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
