CVE-2019-25333 in Momentum JAWS
Summary
by MITRE • 02/13/2026
Bullwark Momentum Series JAWS 1.0 contains a directory traversal vulnerability that allows unauthenticated attackers to access system files by manipulating HTTP request paths. Attackers can exploit the vulnerability by sending crafted GET requests with multiple '../' sequences to read sensitive files like /etc/passwd outside the web root directory.

The vulnerability identified as CVE-2019-25333 affects the Bullwark Momentum Series JAWS 1.0 application, representing a critical directory traversal flaw that undermines the application's security boundaries. This weakness stems from inadequate input validation within the HTTP request processing mechanism, specifically in how the application handles path manipulation sequences. The vulnerability exists at the application layer where user-supplied input is directly incorporated into file system operations without proper sanitization or authorization checks. Such flaws are classified under CWE-22 as "Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')", which is a fundamental security weakness that has been consistently documented across numerous applications and systems. The vulnerability demonstrates a clear breakdown in the principle of least privilege and proper access control implementation.
Attackers can exploit this vulnerability through unauthenticated GET requests that contain multiple '../' sequences in the request path, allowing them to navigate outside the intended web root directory and access sensitive system files. The exploitation process involves crafting HTTP requests that manipulate the application's file resolution logic to traverse directories beyond the designated boundaries. This technique specifically targets the application's failure to properly validate and sanitize user input before using it in file system operations. The ability to read critical system files such as /etc/passwd demonstrates the severity of the vulnerability, as it provides attackers with information about system users and potentially enables further attacks. This exploitation method aligns with ATT&CK technique T1083 (File and Directory Discovery) and T1566 (Phishing for Information), as attackers can use the retrieved information for reconnaissance and privilege escalation.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with unauthorized access to sensitive system resources that could contain credentials, configuration data, or other confidential information. The vulnerability affects the confidentiality and integrity of the system, as unauthorized parties can access files that should remain protected within the application's restricted directory structure. Organizations using Bullwark Momentum Series JAWS 1.0 are at risk of data breaches, system compromise, and potential regulatory violations depending on the nature of the information accessed through this vulnerability. The unauthenticated nature of the attack means that any external party can exploit this weakness without requiring valid credentials, significantly increasing the attack surface and risk exposure. This vulnerability directly impacts the application's security posture and violates fundamental security principles including proper input validation, access control enforcement, and secure coding practices.
Mitigation strategies for CVE-2019-25333 should focus on implementing proper input validation and sanitization mechanisms within the application's HTTP request processing pipeline. Organizations should deploy web application firewalls and input validation rules that prevent directory traversal sequences from being processed by the application. The most effective remediation involves implementing a whitelist-based approach that validates all user-supplied input against a predefined set of acceptable characters and paths. Security patches or updates from the vendor should be applied immediately to address this vulnerability, as the application should enforce proper path validation before any file system operations are performed. Additionally, implementing proper access control measures and restricting file system access to only necessary directories can help minimize the impact of such vulnerabilities. Organizations should also conduct regular security assessments and penetration testing to identify similar weaknesses in their application environments, while ensuring that proper logging and monitoring is in place to detect potential exploitation attempts. The vulnerability underscores the importance of following secure coding practices and implementing defense-in-depth strategies to protect against path traversal attacks.
