Who should care

Organizations running Revive Adserver, especially teams that expose the password-reset flow to users or manage public-facing ad platforms. Administrators should prioritize systems on versions 4.0.0 and earlier.

Technical summary

The NVD record maps this issue to CWE-384 (Session Fixation) and lists affected Revive Adserver versions through 4.0.0. The published CVSS v3.0 vector is 5.9/Medium (AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:N), indicating a network-reachable issue with nontrivial preconditions. The vulnerability is described as occurring in the forgot-password path when setting a new password, where session ID handling can enable session hijacking.

Defensive priority

Medium priority. Patch affected instances promptly, because the issue touches authentication and account recovery flows, but it is not listed in CISA KEV in the supplied record.

Recommended defensive actions

  • Upgrade Revive Adserver to 4.0.1 or later, which the vendor advisory identifies as the fixed release.
  • Inventory installations and confirm no systems remain on version 4.0.0 or earlier.
  • Review password-reset and post-authentication session handling to ensure session IDs are not reused across the reset flow.
  • Invalidate or rotate sessions after password changes and require reauthentication where appropriate.
  • Monitor authentication and password-reset logs for unusual session reuse or account takeover indicators.

Evidence notes

The CVE description explicitly says the flaw is a session fixation issue in the forgot-password mechanism and that it affects Revive Adserver before 4.0.1. The NVD record supplies the affected version range through 4.0.0, the CVSS 3.0 vector, and CWE-384. The CVE references also include a vendor advisory (Revive SA-2017-001) and an oss-security mailing list notice.
