CVE-2024-40690
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIBM InfoSphere Server 11.7 is vulnerable to cross-site scripting. This vulnerability allows an authenticated user to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 297720.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceIBM InfoSphere Server 11.7 contains a stored cross-site scripting (XSS) vulnerability in its Web UI. An authenticated attacker can embed malicious JavaScript code into the interface, which persists and executes in the browsers of other users within trusted sessions, potentially enabling credential theft or session hijacking.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify IBM InfoSphere Information Server versionCheck the installed version of IBM InfoSphere Information Server by inspecting the installation directory, version manifest, or using the IBM installation manager: look for version 11.7 specificallyAffected if The installed version is exactly 11.7 and has not been patched
-
Confirm Web UI component is accessibleVerify the InfoSphere Web UI is enabled and accessible by attempting to access the web interface URL (typically on ports 9080, 9443, or as configured during installation)Affected if The Web UI is exposed and reachable without additional security controls blocking it
-
Check for applied security patchesReview installed fixes and patches for InfoSphere 11.7 through IBM Installation Manager or the patch management console to determine if CVE-2024-40690 fixes have been appliedAffected if No specific patches for this CVE have been installed and the version remains at 11.7
-
Inspect Content Security Policy configurationExamine the Web UI configuration files and HTTP response headers for Content Security Policy (CSP) directives that would restrict inline script executionAffected if CSP headers are missing or configured too permissively (e.g., 'unsafe-inline' is allowed)
A user is affected if they have IBM InfoSphere Information Server version 11.7 running with its Web UI accessible and no CVE-2024-40690 patches applied.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply IBM patches for InfoSphere Server 11.7 as they become available. Implement output encoding and input validation for all user-supplied data in the Web UI, and configure Content Security Policy (CSP) headers to mitigate XSS execution.
