Description

This security bulletin contains information about 1 security vulnerability.


1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2023-42439)

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
