Improper Access Control

CVE-2024-30173

Medium
6.5/10

Summary

The package causal/oidc versions through 2.0.0 are vulnerable to OpenID Connect Authentication (oidc) Bypass. The authentication service of the extension does not verify the OpenID Connect authentication state from the user lookup chain. Instead, the authentication service authenticates every valid frontend user from the user lookup chain, where the frontend user field "tx_oidc" is not empty. In scenarios, where either "ext:felogin" is active or where "$GLOBALS['TYPO3_CONF_VARS']['FE']['checkFeUserPid']" is disabled, an attacker can login to OpenID Connect frontend user accounts by providing a valid username and any password.
