CVE-2022-27546
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 · uneditedHCL iNotes is susceptible to a Reflected Cross-site Scripting (XSS) vulnerability caused by improper validation of user-supplied input supplied with a form POST request. A remote attacker could exploit this vulnerability using a specially-crafted URL to execute script in a victim's web browser within the security context of the hosting web site and/or steal the victim's cookie-based authentication credentials.
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 confidenceHCL iNotes contains a reflected XSS vulnerability where improper validation of user-supplied input in form POST requests allows attackers to inject malicious scripts. When victims click specially-crafted URLs, the injected scripts execute within the security context of the hosting website, enabling session hijacking via stolen cookie-based authentication credentials.

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.
-
Identify if HCL Domino or iNotes is installedCheck for Domino installation directory (Windows: C:\Lotus\Domino or Linux: /opt/ibm/domino), or look for 'IBM\Lotus\Domino' in program files. Also check running services for 'Lotus Domino' or 'IBM Domino'.Affected if HCL Domino server software is present on the system
-
Determine installed Domino versionRun 'domino -version' from the Domino bin directory, or check the version in the Domino Program directory at '..\ Domino\notes.ini' or via the Domino Administrator client. Alternatively, access the Domino web admin at /webadmin and check server version.Affected if Version matches 9.0, 9.0.1, 10.0, 10.0.1, 11.0, 11.0.1, 12.0, or 12.0.1 for Domino; or 9.0.1, 10.0, 10.0.1, 11.0, 11.0.1, 12.0, or 12.0.1 for iNotes
-
Verify iNotes web access is enabledCheck the Domino notes.ini configuration file for 'iNotes_WA Enable' or similar iNotes-related settings. Also confirm the iNotes web database (iNotesWA.nsf) exists in the Domino data directory.Affected if iNotes web access is enabled and the iNotes database files are present and accessible via HTTP/HTTPS
-
Confirm iNotes HTTP servlet is accessibleTest if iNotes responds by accessing a known iNotes URL path such as /iNotes/ or /names.nsf?Login in a web browser. Use curl or a similar tool: curl -I https://yourserver/iNotes/Affected if iNotes servlets respond to HTTP requests, indicating the vulnerable POST form handlers are active
-
Inspect iNotes configuration for input validation settingsReview the iNotes configuration document in Domino Directory (names.nsf) under Configuration - Servers - All Servers Documents. Check for 'iNotes/DAOS' or custom form settings that may control input validation on POST requests.Affected if iNotes is configured with default settings and accepts user-supplied data in form POST requests without explicit input validation rules configured
Your environment is affected if HCL Domino or iNotes is installed with a version matching 9.0.x through 12.0.1 AND the iNotes web interface is enabled and accessible.

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 dataImplement proper input validation and output encoding for all user-supplied data in POST requests within iNotes. Deploy the vendor patch when available and validate the fix does not introduce new attack vectors.
