| Vector | AV:N/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Grafana version 8.4.3
Description
The issue in Grafana is related to the possibility of bypassing the authentication procedure. Exploitation of this issue may allow a remote attacker to elevate their privileges by sending a specially crafted HTTP request. The problem is also described as allowing the reading of files via a specific URI, such as "/dashboard/snapshot/%7B%7Bconstructor.constructor'/../../../../../../etc/passwd". However, the vendor's position is that there is no vulnerability, as this request yields a benign error page, not the content of /etc/passwd.
Recommendations
For Grafana version 8.4.3, consider restricting access to the /dashboard/snapshot/ endpoint to minimize the risk of exploitation. As a temporary workaround, avoid using the
constructor.constructor variable in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
