pyLoad open redirect vulnerability due to improper validation of the is_safe_url function
Summary
Open redirect vulnerability due to incorrect validation of input values when redirecting users after login.
Details
pyload is validating URLs via the get_redirect_url
function when redirecting users at login.
The URL entered in the next
variable goes through the is_safe_url
function, where a lack of validation can redirect the user to an arbitrary domain.
The documentation in the urllib library shows that improper URLs are recognized as relative paths when using the urlparse
function. (https://docs.python.org/3/library/urllib.parse.html#urllib.parse.urlparse)
For example, When an unusual URL like https:///example.com
is entered, urlparse
interprets it as a relative path, but in the actual request it is converted to https://example.com
due to url normalization.
PoC
-
In the next variable, insert the URL to which you want to redirect the user.
-
Check that it is possible to bypass url validation and redirect users to an arbitrary url.
Impact
An attacker can use this vulnerability to redirect users to malicious websites, which can be used for phishing and similar attacks.
