The sample web application in web2py before 2.14.2 might allow remote attackers to execute arbitrary code via vectors involving use of a hardcoded encryption key when calling the session.connect function.

CVE-2016-3954

web2py before 2.14.2 allows remote attackers to obtain the session_cookie_key value via a direct request to examples/simple_examples/status. NOTE: this issue can be leveraged by remote attackers to execute arbitrary code using CVE-2016-3957.

CVE-2016-3957

The secure_load function in gluon/utils.py in web2py before 2.14.2 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.

CVE-2016-4806

Web2py versions 2.14.5 and below was affected by Local File Inclusion vulnerability, which allows a malicious intended user to read/access web server sensitive files.

CVE-2016-4807

CVE-2023-22432

Open redirect vulnerability exists in web2py versions prior to 2.23.1. When using the tool, a web2py user may be redirected to an arbitrary website by accessing a specially crafted URL. As a result, the user may become a victim of a phishing attack.

CVE-2023-45158

An OS command injection vulnerability exists in web2py 2.24.1 and earlier. When the product is configured to use notifySendHandler for logging (not the default configuration), a crafted web request may execute an arbitrary OS command on the web server using the product.
