Path traversal in Grafana - CVE-2021-43798

Vulnerability identifier: #VU58647

CSH Severity: High

CVSS v4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2021-43798

CWE-ID: CWE-22

Exploitation vector: Remote access

Exploit availability: The vulnerability is being exploited in the wild

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences, passed after the "/public/plugins/" URL. A remote non-authenticated attacker can send a specially crafted HTTP request and read arbitrary files on the system.
