The ZOO-Project is an open source processing platform, released under MIT/X11 Licence. A vulnerability in ZOO-Project's WPS (Web Processing Service) implementation allows unauthorized access to files outside the intended directory through path traversal. Specifically, the Gdal_Translate service, when processing VRT (Virtual Format) files, does not properly validate file paths referenced in the VRTRasterBand element, allowing attackers to read arbitrary files on the system. The vulnerability exists because the service doesn't properly sanitize the SourceFilename parameter in VRT files, allowing relative path traversal sequences (../). When combined with VRT's raw data handling capabilities, this allows reading arbitrary files as raw binary data and converting them to TIFF format, effectively exposing their contents. This vulnerability is particularly severe because it allows attackers to read sensitive system files, potentially exposing configuration data, credentials, or other confide…

The ZOO-Project is an open source processing platform. The ZOO-Project Web Processing Service (WPS) Server contains a Cross-Site Scripting (XSS) vulnerability in its EchoProcess service prior to commit 7a5ae1a. The vulnerability exists because the EchoProcess service directly reflects user input in its output without proper sanitization when handling complex inputs.The service accepts various input formats including XML, JSON, and SVG, and returns the content based on the requested MIME type. When processing SVG content and returning it with the image/svg+xml MIME type, the server fails to sanitize potentially malicious JavaScript in attributes like onload, allowing arbitrary JavaScript execution in the victim's browser context. This vulnerability is particularly dangerous because it exists in a service specifically designed to echo back user input, and the lack of proper sanitization in combination with SVG handling creates a reliable XSS vector. Commit 7a5ae1a contains a fix for the…

The ZOO-Project is an open source processing platform. A reflected Cross-Site Scripting vulnerability exists in the ZOO-Project Web Processing Service (WPS) publish.py CGI script prior to commit 7a5ae1a. The script reflects user input from the `jobid` parameter in its HTTP response without proper HTML encoding or sanitization. When a victim visits a specially crafted URL pointing to this endpoint, arbitrary JavaScript code can be executed in their browser context. The vulnerability occurs because the CGI script directly outputs the query string parameters into the HTML response without escaping HTML special characters. An attacker can inject malicious JavaScript code through the `jobid` parameter which will be executed when rendered by the victim's browser. Commit 7a5ae1a contains a fix for the issue.

ZOO-Project is a C-based WPS (Web Processing Service) implementation. A path traversal vulnerability was discovered in Zoo-Project Echo example. The Echo example available by default in Zoo installs implements file caching, which can be controlled by user-given parameters. No input validation is performed in this parameter, which allows an attacker to fully control the file which is returned in the response. Patch was committed in November 22nd, 2024.
