Security Bulletin
Summary
YAJSW(Yet Another Java Service Wrapper) uses Apache Commons and Netty to manage services, launch and monitor application etc. WebSphere eXtreme Scale Liberty deployments, uses YAJSW to register services with the operating system. (CVE-2025-27553, CVE-2025-30474 and CVE-2025-25193).
Vulnerability Details
CVEID: CVE-2025-27553
DESCRIPTION: Relative Path Traversal vulnerability in Apache Commons VFS before 2.10.0.
The FileObject API in Commons VFS has a 'resolveFile' method that
takes a 'scope' parameter. Specifying 'NameScope.DESCENDENT' promises that "an exception is thrown if the resolved file is not a descendent of
the base file". However, when the path contains encoded ".."
characters (for example, "%2E%2E/bar.txt"), it might return file objects that are not
a descendent of the base file, without throwing an exception.
This issue affects Apache Commons VFS: before 2.10.0.
Users are recommended to upgrade to version 2.10.0, which fixes the issue.
CWE: CWE-23: Relative Path Traversal
CVSS Source: CISA ADP
CVSS Base score: 7.5
CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2025-30474
DESCRIPTION: Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Commons VFS.
The FtpFileObject class can throw an exception when a file is not found, revealing the original URI in its message, which may include a password. The fix is to mask the password in the exception message
This issue affects Apache Commons VFS: before 2.10.0.
Users are recommended to upgrade to version 2.10.0, which fixes the issue.
CWE: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
CVSS Source: CISA ADP
CVSS Base score: 5
CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2025-25193
DESCRIPTION: Netty, an asynchronous, event-driven network application framework, has a vulnerability in versions up to and including 4.1.118.Final. An unsafe reading of environment file could potentially cause a denial of service in Netty. When loaded on an Windows application, Netty attempts to load a file that does not exist. If an attacker creates such a large file, the Netty application crash. A similar issue was previously reported as CVE-2024-47535. This issue was fixed, but the fix was incomplete in that null-bytes were not counted against the input limit. Commit d1fbda62d3a47835d3fb35db8bd42ecc205a5386 contains an updated fix.

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.
