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 · unedited
The password reset function in ILIAS 7.0_beta1 through 7.20 and 8.0_beta1 through 8.1 allows remote attackers to take over the account.

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 confidence

The password reset function in ILIAS versions 7.0_beta1 through 7.20 and 8.0_beta1 through 8.1 contains a critical vulnerability allowing remote unauthenticated attackers to bypass the reset mechanism and take over arbitrary user accounts by manipulating the password reset process.

MitigationUpdate ILIAS to the latest patched version (7.21+ or 8.2+) immediately. Review server logs for evidence of exploitation and consider forcing password resets for high-privilege accounts as a precaution.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed ILIAS version
    Locate the ILIAS version file or check the admin dashboard for the current version number. Typical locations include a version.php file in the root directory or the 'Release' information in the Administration > System Settings area.
    Affected if The installed version is 7.0 through 7.20, or 8.0 through 8.1.
  2. Verify password reset functionality is enabled
    Check the ILIAS configuration for the password reset feature. This is typically found in the Administration > Authentication and Registration settings, where the 'Password Reset' or 'Forgot Password' option controls whether the function is active.
    Affected if Password reset is enabled and the version falls within the affected range.
  3. Review authentication configuration for reset token settings
    Examine the authentication configuration files or settings that control the password reset token generation and validation. Look for settings related to token expiration, token uniqueness, or validation logic.
    Affected if The token validation logic permits bypass or the token is not properly tied to the user account being reset.
  4. Inspect access control for password reset endpoints
    Check the web server and ILIAS access control settings to determine if the password reset endpoint is accessible to unauthenticated users. Verify that no IP-based or additional authentication restrictions are applied to the reset URL.
    Affected if The password reset endpoint is reachable without prior authentication.

A user is affected if their ILIAS installation runs version 7.0-7.20 or 8.0-8.1 and the password reset functionality is enabled and publicly accessible.

From vendor data
Upgrade available Upgrade to a release after 8.1
Interim mitigation

Update ILIAS to the latest patched version (7.21+ or 8.2+) immediately. Review server logs for evidence of exploitation and consider forcing password resets for high-privilege accounts as a precaution.
