Incorrect Authorization in Spring Cloud Netflix Zuul
CVE-2021-22113 · GHSA-vwpg-f6gw-rjvf
- Affected
- Maven org.springframework.cloud:spring-cloud-netflix-zuul < 2.2.7
- Fixed in
- 2.2.7· Vendor fix available
- Issue
- Applications using the “Sensitive Headers” functionality in Spring Cloud Netflix Zuul 2.2.6.RELEASE and below may be vulnerable to bypassing the “Sensitive Headers” restriction when executing requests with specially constructed URLs. Applications that use Spring Security's StrictHttpFirewall (enabled by default for all URLs) are not affected by the vulnerability, as they reject requests that allow bypassing.
Recommended action: Upgrade to 2.2.7 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
