Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: SSRF in GeoServer's WPS service. π **Consequences**: Attackers can forge server-side requests, potentially accessing internal networks or sensitive data. It compromises integrity and confidentiality.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: CWE-918 (Server-Side Request Forgery). The OGC Web Processing Service (WPS) allows GET/POST requests that can be manipulated to target internal resources.
π **Attacker Capabilities**: High Confidentiality impact (C:H). Can read internal data. Moderate Integrity (I:L) and Availability (A:L) risks. Can leverage the server to access restricted internal endpoints.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: LOW. CVSS Vector: AV:N/AC:L/PR:N/UI:N/S:U. No authentication (PR:N) or user interaction (UI:N) required. Network accessible (AV:N). Easy to exploit.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: Yes. Proof of Concept (PoC) available via ProjectDiscovery Nuclei templates. Wild exploitation is likely given the low barrier to entry.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for GeoServer WPS endpoints. Use Nuclei templates targeting CVE-2023-43795. Check if the server version is below the patched thresholds.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: Yes. Official patches released in **GeoServer 2.22.5** and **2.23.2**. Refer to GitHub Security Advisory GHSA-5pr3-m5hm-9956.
Q9What if no patch? (Workaround)
π§ **No Patch?**: Isolate the WPS service. Restrict network access to internal resources. Implement WAF rules to block suspicious outbound requests from the WPS endpoint.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: HIGH. Critical severity (C:H), no auth needed, public PoC exists. Immediate patching or mitigation is strongly recommended.
