aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.10.11, the Python parser parses newlines in chunk extensions incorrectly which can lead to request smuggling vulnerabilities under certain conditions. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or `AIOHTTP_NO_EXTENSIONS` is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.10.11 fixes the issue.

    Package        : python-aiohttp     Version        : 3.7.4-1+deb11u1     CVE ID         : CVE-2023-47627 CVE-2023-47641 CVE-2023-49081 CVE-2023-49082                      CVE-2024-23334 CVE-2024-23829 CVE-2024-27306 CVE-2024-30251                      CVE-2024-52304     Debian Bug     :

    Several issues have been found in aiohttp, an asynchronous HTTP     client/server framework for asyncio and Python. Those issues are related     to the HTTP parser, link traversal and XSS on the index pages.

    CVE-2023-47627

         The HTTP parser in AIOHTTP has numerous problems with header          parsing, which could lead to request smuggling. This parser is only          used when AIOHTTP_NO_EXTENSIONS is enabled (or not using a prebuilt          wheel).

    CVE-2023-47641

        Affected versions of aiohttp have a security vulnerability regarding         the inconsistent interpretation of the http protocol. HTTP/1.1 is a         persistent protocol, if both Content-Length(CL) and         Transfer-Encoding(TE) header values are present it can lead to         incorrect interpretation of two entities that parse the HTTP and we         can poison other sockets with this incorrect interpretation. A         possible Proof-of-Concept (POC) would be a configuration with a         reverse proxy(frontend) that accepts both CL and TE headers and         aiohttp as backend. As aiohttp parses anything with chunked, we can         pass a chunked123 as TE, the frontend entity will ignore this header         and will parse Content-Length. The impact of this vulnerability is         that it is possible to bypass any proxy rule, poisoning sockets to         other users like passing Authentication Headers, also if it is         present an Open Redirect an attacker could combine it to redirect         random users to another website and log the request.

    CVE-2023-49081

        Improper validation made it possible for an attacker to modify the         HTTP request (e.g. to insert a new header) or create a new HTTP         request if the attacker controls the HTTP version. The vulnerability         only occurs if the attacker can control the HTTP version of the         request.

    CVE-2023-49082

        Improper validation makes it possible for an attacker to modify the         HTTP request (e.g. insert a new header) or even create a new HTTP         request if the attacker controls the HTTP method. The vulnerability         occurs only if the attacker can control the HTTP method (GET, POST         etc.) of the request. If the attacker can control the HTTP version         of the request it will be able to modify the request (request         smuggling).

    CVE-2024-23334

        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 reading a file 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. Disabling follow_symlinks and using a reverse proxy are         encouraged mitigations.

    CVE-2024-23829

        Security-sensitive parts of the Python HTTP parser retained minor         differences in allowable character sets, that must trigger error         handling to robustly match frame boundaries of proxies in order to         protect against injection of additional requests. Additionally,         validation could trigger exceptions that were not handled         consistently with processing of other malformed input. Being more         lenient than internet standards require could, depending on         deployment environment, assist in request smuggling. The unhandled         exception could cause excessive resource consumption on the         application server and/or its logging facilities.

    CVE-2024-27306

        A XSS vulnerability exists on index pages for static file handling.

    CVE-2024-30251

         In affected versions 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. An attacker can stop the application from          serving requests after sending a single request.

    CVE-2024-52304

        The Python parser parses newlines in chunk extensions incorrectly         which can lead to request smuggling vulnerabilities under certain         conditions. If a pure Python version of aiohttp is installed (i.e.
        without the usual C extensions) or `AIOHTTP_NO_EXTENSIONS` is         enabled, then an attacker may be able to execute a request smuggling         attack to bypass certain firewalls or proxy protections.

    For Debian 11 bullseye, these problems have been fixed in version     3.7.4-1+deb11u1.

    We recommend that you upgrade your python-aiohttp packages.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of aioHTTP installed on the remote host is prior to 3.10.11. It is, therefore, affected by a request smuggling vulnerability. aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.10.11, the Python parser parses newlines in chunk extensions incorrectly which can lead to request smuggling vulnerabilities under certain conditions. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or `AIOHTTP_NO_EXTENSIONS` is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.10.11 fixes the issue.
