Server-Side Template Injection in Yeti Export Function

A SSTI (server side template injection) vulnerability in the custom template export function in yeti-platform yeti before 2.1.12 allows attackers to execute code on the application server.

Casky was already ahead

This CVE exploits attack patterns that Casky's 301matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2024-46507 is a server-side template injection (SSTI) vulnerability in Yeti's custom template export functionality that allows unauthenticated or low-privileged attackers to execute arbitrary code directly on the application server. This vulnerability carries a CVSS score of 7.3 (high) and affects Yeti platform versions before 2.1.12. Organizations using Yeti for threat intelligence management are at risk, as attackers can leverage the vulnerable export feature to achieve remote code execution, potentially compromising sensitive threat data, lateral movement to connected systems, and establishing persistent access. The vulnerability is particularly dangerous because template injection vulnerabilities are often difficult to detect and can be exploited through seemingly benign user inputs.

Casky's 301 matched security skills leverage Claude AI with extended reasoning to detect the attack patterns underlying this vulnerability across two critical MITRE ATT&CK techniques: Initial Access (TA0001) and Resource Development (TA0043). Practitioners using Casky would identify detection patterns for template injection payloads in export requests, anomalous template syntax in user-supplied parameters, and suspicious code execution traces following template processing. The platform's skills enable detection of reconnaissance activities where attackers probe export endpoints for injection points, as well as staged exploitation attempts that gradually escalate from information gathering to code execution. Security teams would see findings correlating malicious template directives with server process spawning, file system access, or network connections—signature patterns that distinguish SSTI exploitation from legitimate template operations.
