Keycloak Information Disclosure via Arbitrary File Path

Detection Guidance

This vulnerability involves a realm administrator submitting an arbitrary filesystem path as a keystore parameter when creating a key provider component in Keycloak. Detection would involve monitoring for such unusual or unauthorized keystore parameter inputs by users with the "manage-realm" role.

There are no specific commands or automated detection methods provided in the available information to detect exploitation attempts or presence of this vulnerability on your system or network.

Executive Summary

This vulnerability exists in Keycloak and can be exploited by a realm administrator who has the "manage-realm" role.

The attacker can submit an arbitrary filesystem path as a keystore parameter when creating a key provider component.

This allows the attacker to probe arbitrary filesystem paths to determine which files exist and are readable by the Keycloak process.

The disclosed information can then be used to identify high-value targets for further attacks.

Impact Analysis

The vulnerability can lead to information disclosure by allowing a realm administrator to discover files on the filesystem that are accessible to the Keycloak process.

This information can be leveraged to identify sensitive or high-value files, which could be targeted in subsequent attacks.

While it does not directly allow modification or deletion of files, the exposure of file existence and readability can increase the risk of further exploitation.
