pyLoad open redirect vulnerability due to improper validation of the is_safe_url function
Open redirect vulnerability due to incorrect validation of input values when redirecting users after login.
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.
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.
An attacker can use this vulnerability to redirect users to malicious websites, which can be used for phishing and similar attacks.Permalink: https://github.com/advisories/GHSA-g3cm-qg2v-2hj5
