CVE-2019-25577 in Ecommerce
Summary
by MITRE • 03/21/2026
SeoToaster Ecommerce 3.0.0 contains a local file inclusion vulnerability that allows authenticated attackers to read arbitrary files by manipulating path parameters in backend theme endpoints. Attackers can send POST requests to /backend/backend_theme/editcss/ or /backend/backend_theme/editjs/ with directory traversal sequences in the getcss or getjs parameters to retrieve file contents.

The CVE-2019-25577 vulnerability affects SeoToaster Ecommerce version 3.0.0 and represents a critical local file inclusion flaw that enables authenticated attackers to access arbitrary files on the server. This vulnerability exists within the backend theme management functionality of the e-commerce platform, specifically in the CSS and JavaScript editing endpoints. The flaw stems from inadequate input validation and sanitization of path parameters that are processed by the application's backend theme handlers.
The technical exploitation of this vulnerability occurs through crafted POST requests sent to specific backend endpoints including /backend/backend_theme/editcss/ and /backend/backend_theme/editjs/. Attackers manipulate the getcss and getjs parameters by injecting directory traversal sequences such as ../ or ..\ to navigate outside of the intended file access boundaries. When the application processes these parameters without proper validation, it executes the file inclusion operations and returns the contents of arbitrary files on the server to the attacker. This allows unauthorized access to sensitive system files, configuration data, and potentially database credentials stored in the web application's file structure.
The operational impact of this vulnerability extends beyond simple information disclosure as it provides attackers with potential access to critical system components and application logic. An authenticated attacker with access to the backend interface can leverage this vulnerability to extract sensitive configuration files, application source code, and potentially gain insights into the system architecture that could facilitate further exploitation. The vulnerability is particularly concerning because it requires only authenticated access to the backend, which may be obtained through credential compromise or social engineering attacks against administrative users.
Security practitioners should note that this vulnerability aligns with CWE-22, which describes improper limitation of a pathname to a restricted directory, commonly known as path traversal. The flaw also maps to ATT&CK technique T1213.002, which involves data from information repositories, as attackers can extract sensitive data from the compromised system. Organizations using SeoToaster Ecommerce 3.0.0 should prioritize immediate patching and implement additional security controls including input validation, parameterized queries, and proper access controls to prevent unauthorized access to backend functionality. Network segmentation and monitoring of backend API endpoints can also help detect and prevent exploitation attempts. The vulnerability demonstrates the importance of validating all user-supplied input in web applications and implementing proper file access controls to prevent directory traversal attacks that could lead to complete system compromise.
