Debian DLA-2950-1 : python-scrapy - LTS security update
medium Nessus Plugin ID 158996
Language:
Synopsis
The remote Debian host is missing one or more security-related updates.Description
The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2950 advisory.- Scrapy is a high-level web crawling and scraping framework for Python. If you use `HttpAuthMiddleware` (i.e. the `http_user` and `http_pass` spider attributes) for HTTP authentication, all requests will expose your credentials to the request target. This includes requests generated by Scrapy components, such as `robots.txt` requests sent by Scrapy when the `ROBOTSTXT_OBEY` setting is set to `True`, or as requests reached through redirects. Upgrade to Scrapy 2.5.1 and use the new `http_auth_domain` spider attribute to control which domains are allowed to receive the configured HTTP authentication credentials. If you are using Scrapy 1.8 or a lower version, and upgrading to Scrapy 2.5.1 is not an option, you may upgrade to Scrapy 1.8.1 instead. If you cannot upgrade, set your HTTP authentication credentials on a per-request basis, using for example the `w3lib.http.basic_auth_header` function to convert your credentials into a value that you can assign to the `Authorization` header of your request, instead of defining your credentials globally using `HttpAuthMiddleware`. (CVE-2021-41125)
- Exposure of Sensitive Information to an Unauthorized Actor in GitHub repository scrapy/scrapy prior to 2.6.1. (CVE-2022-0577)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Upgrade the python-scrapy packages.For Debian 9 stretch, these problems have been fixed in version 1.0.3-2+deb9u1.
