CVE-2023-27861
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 Maximo Application Suite - Manage Component 8.8.0 and 8.9.0 transmits sensitive information in cleartext that could be intercepted by an attacker using man in the middle techniques. IBM X-Force ID: 249208.
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 · high confidenceIBM Maximo Application Suite Manage Component versions 8.8.0 and 8.9.0 transmit sensitive information in cleartext without encryption, allowing a man-in-the-middle attacker to intercept and read sensitive data being communicated between clients and the server.

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 the installed Maximo Application Suite versionAccess the Maximo administration console or check the installed packages using the version lookup command specific to the installation method (e.g., ps -ef | grep maximo, or check the installation directory for version files)Affected if The installed version is exactly 8.8.0 or exactly 8.9.0
-
Verify HTTPS is enabled for the Manage componentInspect the IBM Maximo configuration files (such as maximo.properties or web.xml) and check if the server is configured to require HTTPS connections. Look for properties like 'mxe.webui.protocol' set to 'https' or similar SSL enforcement settingsAffected if HTTPS is not enforced or the protocol is set to HTTP for sensitive endpoints
-
Check SSL/TLS certificate configurationExamine the application server (typically WebSphere or Liberty) SSL configuration. Verify that valid SSL certificates are installed and that the server is configured to reject non-encrypted connectionsAffected if No valid SSL certificate is configured or cleartext HTTP listeners are active for sensitive services
-
Capture network traffic to confirm encryption statusUse a network packet capture tool (such as tcpdump or Wireshark) on the client-server communication path to inspect whether sensitive data (login credentials, personal information, business data) is transmitted in plaintext versus encrypted TLS packetsAffected if Sensitive data is observed being transmitted in cleartext over HTTP rather than encrypted HTTPS traffic
You are affected if your IBM Maximo Application Suite Manage component is version 8.8.0 or 8.9.0 AND sensitive data is transmitted over unencrypted HTTP connections instead of HTTPS with proper TLS.

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 dataEnable TLS encryption for all sensitive data transmission, configure the application to use HTTPS exclusively, and ensure valid SSL certificates are properly installed and enforced.
