CVE-2024-23334
Summary
Improperly configuring static resource resolution in aiohttp when used as a web server can result in the unauthorized reading of arbitrary files on the system.
Details
When using aiohttp as a web server and configuring static routes, it is necessary to specify the root path for static files. Additionally, the option 'follow_symlinks' can be used to determine whether to follow symbolic links outside the static root directory. When 'follow_symlinks' is set to True, there is no validation to check if a given file path is within the root directory.This can lead to directory traversal vulnerabilities, resulting in unauthorized access to arbitrary files on the system, even when symlinks are not present.
i.e. An application is only vulnerable with setup code like:
Impact
This is a directory traversal vulnerability with CWE ID 22. When using aiohttp as a web server and enabling static resource resolution with
follow_symlinksset to True, it can lead to this vulnerability. This vulnerability has been present since the introduction of thefollow_symlinksparameter.Workaround
Even if upgrading to a patched version of aiohttp, we recommend following these steps regardless.
If using
follow_symlinks=Trueoutside of a restricted local development environment, disable the option immediately. This option is NOT needed to follow symlinks which point to a location within the static root directory, it is only intended to allow a symlink to break out of the static directory. Even with this CVE fixed, there is still a substantial risk of misconfiguration when using this option on a server that accepts requests from remote users.Additionally, aiohttp has always recommended using a reverse proxy server (such as nginx) to handle static resources and not to use these static resources in aiohttp for production environments. Doing so also protects against this vulnerability, and is why we expect the number of affected users to be very low.
Patch: https://github.com/aio-libs/aiohttp/pull/8079/files
CVE-2024-27306
Summary
A XSS vulnerability exists on index pages for static file handling.
Details
When using
web.static(..., show_index=True), the resulting index pages do not escape file names.If users can upload files with arbitrary filenames to the static directory, the server is vulnerable to XSS attacks.
Workaround
We have always recommended using a reverse proxy server (e.g. nginx) for serving static files. Users following the recommendation are unaffected.
Other users can disable
show_indexif unable to upgrade.Patch: https://github.com/aio-libs/aiohttp/pull/8319/files
CVE-2024-30251
Summary
An attacker can send a specially crafted POST (multipart/form-data) request. When the aiohttp server processes it, the server will enter an infinite loop and be unable to process any further requests.
Impact
An attacker can stop the application from serving requests after sending a single request.
For anyone needing to patch older versions of aiohttp, the minimum diff needed to resolve the issue is (located in
_read_chunk_from_length()):This does however introduce some very minor issues with handling form data. So, if possible, it would be recommended to also backport the changes in:
aio-libs/aiohttp@cebe526
aio-libs/aiohttp@7eecdff
aio-libs/aiohttp@f21c6f2
