In the /license/ endpoint, the detailed view key is not properly validated and sanitized, which can result in a potential cross-site scripting (XSS) vulnerability when attempting to access a detailed license view that does not exist.
In the /license/ endpoint, the license_details_view function is vulnerable to a potential cross-site scripting (XSS) attack due to inadequate validation and sanitization of the key parameter. This vulnerability arises when attempting to access a key with malicious javascript.
def license_details_view(request, key):
"""
Display all available information about a given license `key` followed by
the full license text.
"""
licenses = get_licenses()
try:
data = saneyaml.dump(licenses[key].to_dict())
text = licenses[key].text
except KeyError:
return HttpResponseNotFound(f"License {key} not found.") # Leads to cross-site scripting when key is malicious javascript
return HttpResponse(f"<pre>{data}</pre><hr><pre>{text}</pre>")
Attackers can exploit the vulnerability to inject malicious scripts into the response generated by the license_details_view function. When unsuspecting users visit the page, their browsers will execute the injected scripts, leading to unauthorized actions, session hijacking, or stealing sensitive information.
