This could have led to user confusion and possible spoofing attacks. Successful exploitation of this vulnerability may allow attackers to access restricted functions.Ī website could have obscured the full screen notification by using the file open dialog. Successful exploitation of this vulnerability may allow attackers to access restricted functions. The Bluetooth module of some Huawei Smart Screen products has an identity authentication bypass vulnerability. A proxy could be leveraged to clear the `authentication` cookie for the Graylog server URL for the `/api/system/sessions` endpoint, as that is the only one vulnerable. Unpatched this vulnerability exists, but is relatively hard to exploit. Using short session expiration and explicit log outs of unused sessions can help limiting the attack vector. Graylog 5.1.11 and 5.2.4, and any versions of the 6.0 development branch, contain patches to not re-use sessions under any circumstances. The complexity of such an attack is high, because it requires presenting a spoofed login screen and injection of a session cookie into an existing browser, potentially through a cross-site scripting attack. In this case, the pre-existing session could be used to gain elevated access to an existing Graylog login session, provided the malicious user could successfully inject their session cookie into someone else's browser. Starting in version 4.3.0 and prior to versions 5.1.11 and 5.2.4, reauthenticating with an existing session cookie would re-use that session id, even if for different user credentials. Graylog is a free and open log management platform.
