CVE-2022-21702· NVD / CVE Program· CNA GitHub_M

Cross site scripting in Grafana proxy

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.3% (FIRST EPSS); higher than 83.3% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: grafana (AlmaLinux:8) 7.5.15-3.el8; grafana (AlmaLinux:9) 7.5.15-3.el9; github.com/grafana/grafana (Go) 7.5.15, 8.3.5.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to grafana (AlmaLinux:8) 7.5.15-3.el8; grafana (AlmaLinux:9) 7.5.15-3.el9; github.com/grafana/grafana (Go) 7.5.15, 8.3.5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Grafana is an open-source platform for monitoring and observability. In affected versions an attacker could serve HTML content thru the Grafana datasource or plugin proxy and trick a user to visit this HTML page using a specially crafted link and execute a Cross-site Scripting (XSS) attack. The attacker could either compromise an existing datasource for a specific Grafana instance or either set up its own public service and instruct anyone to set it up in their Grafana instance. To be impacted, all of the following must be applicable. For the data source proxy: A Grafana HTTP-based datasource configured with Server as Access Mode and a URL set, the attacker has to be in control of the HTTP server serving the URL of above datasource, and a specially crafted link pointing at the attacker controlled data source must be clicked on by an authenticated user. For the plugin proxy: A Grafana HTTP-based app plugin configured and enabled with a URL set, the attacker has to be in control of the HTTP server serving the URL of above app, and a specially crafted link pointing at the attacker controlled plugin must be clocked on by an authenticated user. For the backend plugin resource: An attacker must be able to navigate an authenticated user to a compromised plugin through a crafted link. Users are advised to update to a patched version. There are no known workarounds for this vulnerability.

This is a cross-site scripting (XSS) vulnerability. A well-configured Content-Security-Policy doesn't fix it, but greatly reduces its impact. Check your site's CSP and other security headers for free.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
