Summary
It was discovered that web2py does not properly check denied hosts before
verifying passwords. An attacker could possibly use this issue to perform
brute-force attacks. (CVE-2016-10321)
It was discovered that web2py allows remote attackers to obtain
environment variable values. An attacker could possibly use this issue to
gain administrative access. (CVE-2016-3952)
It was discovered that web2py uses a hardcoded encryption key. An
attacker could possibly use this issue to execute arbitrary code.
(CVE-2016-3953, CVE-2016-3954, CVE-2016-3957)

Vulnerabilities 5
-
Critical 9.8
web2py is vulnerable to password brute-force attack
web2py before 2.14.6 does not properly check if a host is denied before verifying passwords, allowing a remote attacker to perform brute-force attacks.
-
Critical 9.8
web2py remote code execution via hardcoded encryption key in session.connect function
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.
-
Medium 5.5
web2py exposure of sensitive information
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.
