What Undercode Says:
GeoNode Vulnerable to SSRF Attack (CVE-2023-40017)
Researchers discovered a critical SSRF vulnerability in GeoNode, a platform for managing geospatial data. This vulnerability allows attackers to exploit a flaw in the `/proxy/?url=` endpoint to fetch information from internal servers on the system running GeoNode.
Technical Details
The `/proxy/?url=` endpoint lacks proper safeguards against SSRF attacks. An attacker can use this endpoint to:
Scan internal networks: By crafting specific URLs, attackers can determine if internal hosts are alive.
Extract information: With additional techniques like hash fragments, attackers can potentially steal metadata from internal systems.
Impact
A successful SSRF exploit can grant attackers unauthorized access to sensitive internal resources and information. This could lead to data breaches, compromised systems, and disrupted operations.
Recommendation
Update GeoNode to the latest patched version (4.4.1 or later) which addresses this vulnerability.
Review your GeoNode configuration and restrict access to the `/proxy/` endpoint if possible.
Implement security measures to prevent unauthorized access to internal systems.
