CVE-2022-31123: Plugin signature bypass It is possible to bypass plugin signatures by exploiting a versioning flaw in Grafana. An attacker can convince a server admin to download and successfully run a malicious plugin even though unsigned plugins <https://go.grafana.com/MzU2LVlGRy0zODkAAAGHKffeRdXtITNJ57jRLGNoDYneVd-OEEcBdv-IjxVZkAZsJruum93h2vIohJ4utenGSY7smU=> are not allowed.

Affected versions: Grafana <= 9.1.x

Grafana is an open-source platform for monitoring and observability.

Starting with the 7.0 branch, Grafana had a stored XSS vulnerability in the trace view visualization.

The stored XSS vulnerability was possible due the value of a span's attributes/resources were not properly sanitized and this will be rendered when the span's attributes/resources are expanded.

An attacker needs to have the Editor role in order to change the value of a trace view visualization to contain JavaScript.

This means that vertical privilege escalation is possible, where a user with Editor role can change to a known password for a user having Admin role if the user with Admin role executes malicious JavaScript viewing a dashboard.

Users may upgrade to version 8.5.21, 9.2.13 and 9.3.8 to receive a fix.

A signature verification vulnerability exists in crewjam/saml. This flaw allows an attacker to bypass SAML Authentication. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
