DescriptionCVE.org

A vulnerability has been found in Song-Li cross_browser up to ca690f0fe6954fd9bcda36d071b68ed8682a786a. This affects an unknown part of the file flask/uniquemachine_app.py of the component details Endpoint. Such manipulation of the argument ID leads to sql injection. The attack can be executed remotely. The exploit has been disclosed to the public and may be used. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

SQL injection in Song-Li cross_browser application allows remote code execution via unsanitized ID parameter in the details endpoint of flask/uniquemachine_app.py. The vulnerability affects all versions up to commit ca690f0fe6954fd9bcda36d071b68ed8682a786a, requires no authentication, and has publicly available exploit code. The vendor has not responded to disclosure attempts, and the product's rolling-release model means no traditional patched version has been released.

Technical ContextAI

The vulnerability exists in a Flask-based web application (cross_browser) written in Python. The flaw is a classic SQL injection (CWE-89) where user-supplied input in the ID parameter of the details endpoint in flask/uniquemachine_app.py is passed directly into SQL queries without proper parameterization or sanitization. This allows an attacker to inject arbitrary SQL commands. The attack surface is a remote HTTP endpoint with no authentication requirement (PR:N in CVSS vector), making it trivially accessible. The underlying issue is the failure to use prepared statements or input validation before constructing dynamic SQL queries.

RemediationAI

Given the vendor's non-responsiveness and rolling-release model, remediation requires direct source code patching. Developers should immediately review and fix the vulnerable code in flask/uniquemachine_app.py by implementing parameterized SQL queries (prepared statements) for the details endpoint ID parameter, ensuring all user input is properly escaped or bound to query placeholders. Organizations unable to patch source code directly should implement a Web Application Firewall (WAF) with SQL injection detection rules to block malicious ID parameters, restrict network access to the affected endpoint via firewall rules or authentication layers, and consider isolating the application until patching is completed. The public exploit at https://github.com/wing3e/public_exp/issues/24 should be reviewed to understand the exact attack vector.
