Open Redirect

web2py is open source full-stack enterprise framework for agile development of secure database-driven web-based applications, written and programmable in Python.

Affected versions of this package are vulnerable to Open Redirect in gluon/tools.py. It allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the _next parameter to user/logout.

How to fix Open Redirect?

Upgrade web2py to version 2.12.1 or higher.

Arbitrary Code Execution

web2py is an open source full-stack enterprise framework for agile development of secure database-driven web-based applications, written and programmable in Python.

Affected versions of this package are vulnerable to Arbitrary Code Execution. The secure_load function in gluon/utils.py uses pickle.loads to deserialize session information stored in cookies, which might allow remote attackers to execute arbitrary code by leveraging knowledge of encryption_key.

How to fix Arbitrary Code Execution?

Upgrade web2py to version 2.14.2 or higher.
