Security Bulletin: IBM Documentation Offline is vulnerable to information disclosure, session forgery and remote code execution

Security Bulletin


Summary

IBM Documentation Offline is a desktop application that bundles an Electron-based viewer and an embedded Node.js web server to serve product documentation locally on the user's workstation. Multiple vulnerabilities have been identified in the embedded server component spanning three weakness categories. Information Disclosure: Two vulnerabilities could allow a network-adjacent attacker to obtain information. The embedded server bound its network sockets to all available network interfaces rather than restricting them to the local loopback address. Additionally, insufficient restriction on file-path input could allow an attacker to read files outside the intended documentation directory. Session Integrity: The embedded server uses a hardcoded session secret by default. An attacker with access to the service could forge structurally valid session tokens and manipulate client-side state. Arbitrary Code Execution: Two related vulnerabilities could allow an attacker to execute arbitrary code within the privilege context of the desktop application. The first involves improper neutralization of log output. The second involves external control of a file path supplied to the server's template engine.

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.
