Executive Summary

CVE-2024-46507 is a Server-Side Template Injection (SSTI) vulnerability found in the Yeti Platform, a forensic intelligence tool used by DFIR teams. This vulnerability exists in versions 2.0 to 2.1.11 of the platform. It allows attackers to exploit the custom template export function by creating malicious templates that, when used to export observables like IP addresses or hashes, can execute arbitrary code on the application server.

Impact Analysis

This vulnerability can have serious impacts as it allows attackers to execute arbitrary commands on the server hosting the Yeti Platform. This could enable them to collect sensitive intelligence, modify or delete Indicators of Compromise (IoCs), and potentially take control of the server. In default configurations, combined with another vulnerability (CVE-2024-46508), attackers could achieve unauthenticated remote code execution, increasing the risk of unauthorized access and data compromise.

Detection Guidance

This vulnerability can be detected by testing the custom report template export function in Yeti Platform versions 2.0 to 2.1.11 for Server-Side Template Injection (SSTI) flaws.

One approach is to create a malicious template that includes payloads designed to execute code when exported. Observing whether arbitrary commands execute on the server indicates the presence of the vulnerability.

A proof-of-concept exploit is available in Rhino Security Labs' CVE GitHub repository, which can be used to verify if the system is vulnerable.

Specific commands are not provided in the available resources, but testing typically involves crafting templates with SSTI payloads and exporting observables such as IP addresses or hashes to trigger code execution.

Mitigation Strategies

The immediate mitigation step is to upgrade the Yeti Platform to version 2.1.12 or later, where this SSTI vulnerability has been patched.

Additionally, be aware of related vulnerabilities such as CVE-2024-46508, which involves a static insecure JWT secret in default deployments, as combined exploitation could lead to unauthenticated remote code execution.

Until the upgrade is applied, restrict access to the custom report template export functionality and monitor for suspicious activity related to template exports.
