Micronaut management endpoints vulnerable to drive-by localhost attack
CVE-2024-23639 · GHSA-583g-g682-crxf
- Affected
- Maven io.micronaut:micronaut-http-server-tck < 3.8.3
- Fixed in
- 3.8.3· Vendor fix available
- Issue
- Enabled but unsecured management endpoints are susceptible to drive-by localhost attacks. While not typical of a production application, these attacks may have more impact on a development environment where such endpoints may be flipped on without much thought. Details A malicious/compromised website can make HTTP requests to localhost. Normally, such requests would trigger a CORS preflight check which would prevent the request; however, some requests are "simple" and do not require a preflight check. These endpoints, if enabled and not secured, are vulnerable to being triggered. Impact Production environments typically disable unused endpoints and secure/restrict access to needed endpoints. A more likely victim is the developer in their local development host, who has enabled endpoints without security for the sake of easing development.
Recommended action: Upgrade to 3.8.3 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
