1) Server-Side Request Forgery (SSRF)

EUVDB-ID: #VU80845

Risk: Medium

CVSSv3.1: 5.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N/E:P/RL:U/RC:C]

CVE-ID: CVE-2023-42439

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input when processing the "@" character or it encoded value (e.g. %40). A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.

Example:

GET /proxy/?url=http://development.demo.geonode.org%40geoserver:8080/geoserver/web

Mitigation
