Overview

CVE-2025-69602 describes a session fixation weakness in 66biolinks version 62.0.0 by AltumCode. The application keeps the same session identifier after a user signs in, so the value is not renewed at the authentication boundary. The CWE supplied in the record is CWE-384 (Session Fixation).

Impact

  • The record states that an attacker who can set or predict a session ID could potentially hijack an authenticated session.
  • The NVD CVSS 3.1 data indicates a network attack vector, low complexity, no privileges required and no user interaction, with high confidentiality and integrity impact and no availability impact.
  • The record rates the score 9.1 as critical.

Affected products and versions

  • Product: Altumcode 66biolinks.
  • Affected version listed: version 62.0.0.
  • The record does not list other affected versions or a fixed version.

Exploitation status

  • The CISA KEV catalog does not list this CVE according to the record, so no active exploitation is claimed here.
  • No confirmed exploitation appears in the sources consulted.
  • The record includes a third-party reference tagged as exploit-related. This analysis does not reproduce or describe its content.

Remediation and mitigation

  • No fixed version is listed in the record. This does not prove that no fix exists, so check the vendor channel for a newer release and apply it once verified.
  • Until a fix is confirmed, restrict access to login and administrative interfaces where feasible, for example through network controls or VPN access.
  • Enforce HTTPS and secure cookie attributes for session cookies at the web server or proxy level.
  • Review whether the application can invalidate existing sessions at login. If it cannot, plan a change with the vendor or a qualified developer.

Detection guidance

  • Review authentication logs for session identifiers that persist across logins or appear from multiple client addresses.
  • Monitor for authenticated activity that starts from a session that was not issued after a successful login.
  • Alert on unusual account activity following logins from shared or public browsers.

Limitations of the available information

  • The record gives no fixed version, no vendor advisory link and no detail on the exact session mechanism or cookie name.
  • EPSS and SSVC values are absent from the record.
  • The vendor response status is unknown from the sources consulted.

Frequently asked questions
