Proxy Endpoint Vulnerabliity

High
inodb published GHSA-9h44-r3c3-q7rm Jul 23, 2024

Package

cBioPortal

Affected versions

<=v6.0.11

Patched versions

>=v6.0.12

Description

Impact

When running a publicly exposed proxy endpoint without authentication it could allow someone to perform a Server Side Request Forgery (SSRF) attack. Logged in users could do the same on private instances.

Patches

Fixed in #10884. Released in https://github.com/cBioPortal/cbioportal/releases/tag/v6.0.12

Workarounds

Might be able to disable /proxy endpoint entirely via e.g. nginx

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Server-Side Request Forgery (SSRF)

The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. Learn more on MITRE.
