Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Apache Solr leaks sensitive host environment variables via its Metrics API.β¦
π‘οΈ **Root Cause**: CWE-200 (Exposure of Sensitive Information). <br>π **Flaw**: The Solr Metrics API exposes all unprotected environment variables.β¦
π¦ **Affected**: Apache Solr versions **9.0.0 to 9.3.0** (prior to 9.3.0). <br>π’ **Vendor**: Apache Software Foundation.
Q4What can hackers do? (Privileges/Data)
π΅οΈ **Hackers Can**: Read sensitive environment variables set on the host machine. <br>π **Data**: This includes API keys, database credentials, or other secrets not explicitly filtered by Solr's default configuration.
Q5Is exploitation threshold high? (Auth/Config)
β οΈ **Threshold**: **Low**. <br>π **Auth**: No authentication required to access the Metrics API endpoint. <br>βοΈ **Config**: Exploitable if the default configuration is used (which is common).
Q6Is there a public Exp? (PoC/Wild Exploitation)
π» **Public Exp?**: **Yes**. <br>π **PoC**: Available via Nuclei templates (`CVE-2023-50290.yaml`) and documented in bug bounty reports by Desai Vinayak.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for the Solr Metrics API endpoint. <br>π§ͺ **Test**: Check if environment variables are returned in the JSON response. Use automated scanners like Nuclei with the specific CVE template.
π₯ **Urgency**: **High**. <br>β³ **Priority**: Immediate patching or mitigation required. The vulnerability allows easy access to critical secrets without authentication.
