IBM Rational Engineering Lifecycle Manager 5.0 through 5.02 and 6.0 through 6.0.6 is vulnerable to cross-site scripting. This vulnerability allows users 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: 144885.

Security readout for executives and security teams

Plain-English summary

CVE-2018-1659 is a cross-site scripting issue in IBM Rational Engineering Lifecycle Manager. An authenticated user could place JavaScript into the Web UI, potentially changing page behavior and exposing credentials during a trusted session. This is not listed as KEV in the provided source bundle.

Executive priority

Treat as a moderate-priority application security fix. It can affect credential confidentiality inside trusted sessions, but the provided evidence indicates authentication and user interaction are required, and no active exploitation signal is cited.

Technical view

IBM RELM versions 5.0 through 5.02 and 6.0 through 6.0.6 are affected. CVSS 3.0 score is 5.4 with network attack vector, low complexity, low privileges required, user interaction required, changed scope, and low confidentiality and integrity impact.

Likely exposure

Exposure is most likely in organizations still running affected IBM RELM releases with authenticated user access to the Web UI. The issue is not described as unauthenticated remote compromise in the provided sources.

Exploitation context

The CVSS vector indicates exploitation requires a logged-in user and user interaction. The bundle does not cite active exploitation, public exploit use, or CISA KEV inclusion, so active exploitation should not be assumed.

Researcher notes

The source bundle does not provide exact vulnerable parameters, fixed versions, workarounds, or exploit details. Validation should stay at inventory, configuration, patch-state, and safe application behavior checks unless IBM guidance supplies more detail.

Mitigation direction

  • Inventory IBM RELM deployments and versions.
  • Prioritize versions 5.0 through 5.02 and 6.0 through 6.0.6.
  • Review IBM advisory ibm10731511 for official remediation guidance.
  • Apply IBM-supported updates or mitigations where applicable.
  • Restrict RELM Web UI access to trusted users while remediation is pending.

Validation and detection

  • Confirm whether IBM RELM is present in asset inventory.
  • Verify installed versions against the affected version ranges.
  • Check whether IBM advisory remediation has been applied.
  • Review authenticated Web UI roles with content-entry privileges.
  • Confirm user-supplied Web UI content is safely handled after remediation.
