Description

This security bulletin contains information about 1 vulnerability.


1) Server-Side Request Forgery (SSRF) (CVE-ID: N/A)

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

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to perform server-side request forgery.

The vulnerability exists due to improper restriction of server-side requests in the WMS GetMap, GetLegendGraphic, and GetStyles request handlers when processing an SLD parameter containing a URL. A remote attacker can send a crafted WMS request containing an attacker-controlled SLD URL to perform server-side request forgery.

The SLD functionality is enabled by default when the relevant metadata flag is unset.
