GHSA-4x49-w62v-76q7

MEDIUM

GHSA-4x49-w62v-76q7 is a medium-severity (CVSS 6.5) Path Traversal vulnerability in org.springframework.cloud:spring-cloud-config-server. 5 public exploit references exist, so weaponization risk is real. O3 Security confirms whether GHSA-4x49-w62v-76q7 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Spring Cloud Config, versions 2.1.x prior to 2.1.2, versions 2.0.x prior to 2.0.4, and versions 1.4.x prior to 1.4.6, and older unsupported versions allow applications to serve arbitrary configuration files through the spring-cloud-config-server module. A malicious user, or attacker, can send a request using a specially crafted URL that can lead a directory traversal attack.

Spring Cloud Config 2.1.x - Path Traversal (Metasploit)

by Dhiraj Mishra · Apr 30, 2019

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.springframework.cloud:spring-cloud-config-server. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update org.springframework.cloud:spring-cloud-config-server to 1.4.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4x49-w62v-76q7 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-4x49-w62v-76q7 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-4x49-w62v-76q7. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
