Description

This security bulletin contains information about 1 vulnerability.


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

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

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/E:P/U:Green


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
