Описание
In versions up to and including 4.5.29 (4.x branch) and 5.1.4 (5.x branch), the WebClientSession component of Eclipse Vert.x Web Client does not validate that the Domain attribute of a Set-Cookie response header matches the originating server's domain, in violation of RFC 6265 section 5.3.
An attacker who controls any server that the victim application contacts can inject a cookie scoped to an arbitrary third-party domain; because the session store performs no cross-domain ownership check, it stores and later transmits that cookie to the targeted domain.
When the victim application subsequently sends a request to the targeted domain using the same WebClientSession, it presents the attacker-injected cookie, causing the receiving service to process the request under the attacker's account. Sensitive data included in the victim application's requests, such as payment amounts, card details, or other API payloads, may then be accessible to the attacker through their own account on that service.
A flaw was found in Eclipse Vert.x Web Client. The WebClientSession component does not properly validate the Domain attribute of a Set-Cookie response header against the originating server's domain. This vulnerability allows a remote attacker to inject a cookie scoped to an arbitrary third-party domain. When the victim application subsequently sends a request to the targeted domain, the injected cookie is presented, potentially leading to information disclosure and unauthorized access to sensitive data through the attacker's account on that service.
Отчет
This is an Important information disclosure flaw in Eclipse Vert.x Web Client's WebClientSession component. The vulnerability arises from insufficient validation of the Domain attribute in Set-Cookie response headers, allowing a remote attacker to inject cookies scoped to arbitrary third-party domains. This could lead to sensitive data exposure and unauthorized access if a victim application subsequently sends requests to the targeted domain, presenting the attacker-controlled cookie. The impact is significant as it bypasses expected cross-domain security boundaries.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
