CVE-2020-13409 in SecureTrack
Summary
by MITRE • 02/09/2021
Tufin SecureTrack < R20-2 GA contains reflected + stored XSS (as in, the value is reflected back to the user, but is also stored within the DB and can be later triggered again by the same victim, or also later by different users). Both stored, and reflected payloads are triggerable by admin, so malicious non-authenticated user could get admin level access. Even malicious low-privileged user can inject XSS, which can be executed by admin, potentially elevating privileges and obtaining admin access. (issue 3 of 3)

The vulnerability identified as CVE-2020-13409 affects Tufin SecureTrack versions prior to R20-2 GA and represents a critical cross-site scripting flaw that combines both reflected and stored attack vectors. This vulnerability exists within the application's input validation mechanisms, allowing attackers to inject malicious scripts that execute in the context of affected users' browsers. The flaw is particularly dangerous because it enables both immediate reflected execution and persistent stored exploitation, meaning that malicious payloads can be triggered multiple times by different users and persist within the database for extended periods.
The technical implementation of this vulnerability stems from insufficient sanitization of user-supplied input across multiple application endpoints. When user data is processed and subsequently rendered back to users without proper encoding or validation, attackers can inject malicious javascript code that gets executed in the victim's browser context. The reflected component occurs when the application returns user input directly to the browser without sanitization, while the stored aspect arises when malicious input is persisted in the database and later retrieved and executed during normal application operation. This dual nature significantly increases the attack surface and potential impact of the vulnerability.
The operational impact of CVE-2020-13409 is severe and multifaceted, particularly due to the privilege escalation potential it presents. The vulnerability allows unauthenticated attackers to potentially gain administrative access to the SecureTrack system, as the flaw can be exploited by malicious users with minimal privileges to inject payloads that execute with administrative privileges when processed by admin users. This creates a pathway for attackers to escalate their privileges from low-privileged users to full administrative control, potentially compromising the entire network security infrastructure managed by SecureTrack. The stored nature of the vulnerability means that attacks can be executed repeatedly against different users over time, making detection and remediation more challenging.
Security professionals should implement immediate mitigations including comprehensive input validation and output encoding across all user-facing application components. The recommended approach involves applying proper HTML entity encoding to all user-supplied data before rendering it in web pages, implementing Content Security Policy headers to restrict script execution, and conducting thorough input sanitization at all application entry points. Additionally, the application should enforce strict access controls and privilege separation to limit the impact of potential exploitation. Organizations should also consider implementing web application firewalls and monitoring for suspicious input patterns that may indicate XSS attack attempts. The vulnerability aligns with CWE-79 (Cross-site Scripting) and maps to ATT&CK technique T1059.007 (Command and Scripting Interpreter: JavaScript) within the adversary tactics framework, emphasizing the need for comprehensive defensive measures across multiple security layers.
