  1. CVE-2022-21716

    Hoch · CVSS 7.5EPSS 3,51%Korrektur verfügbar

    Buffer Overflow in Twisted

    Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 22.2.0, Twisted SSH client and server implement is able to accept an infinite amount of data for the peer's SSH version identifier. This ends up with a buffer using all the available memory. The attach is a simple as `nc -rv localhost 22 < /dev/zero`. A patch is available in version 22.2.0. There are currently no known workarounds.

    Hoch · CVSS 7.5EPSS 1,38%Korrektur verfügbar

    Cookie and header exposure in twisted

    twisted is an event-driven networking engine written in Python. In affected versions twisted exposes cookies and authorization headers when following cross-origin redirects. This issue is present in the `twited.web.RedirectAgent` and `twisted.web. BrowserLikeRedirectAgent` functions. Users are advised to upgrade. There are no known workarounds.

  3. CVE-2020-10108

    Kritisch · CVSS 9.8EPSS 3,97%Korrektur verfügbar

    CVE-2020-10108

    In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request.

    Kritisch · CVSS 9.8EPSS 3,29%Korrektur verfügbar

    CVE-2020-10109

    In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with a content-length and a chunked encoding header, the content-length took precedence and the remainder of the request body was interpreted as a pipelined request.

  5. CVE-2019-9515

    Hoch · CVSS 7.5EPSS 87,29%Korrektur verfügbar

    Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service

    Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.

  6. CVE-2019-9512

    Hoch · CVSS 7.5EPSS 83,43%Korrektur verfügbar

    Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service

    Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.

  7. CVE-2019-9514

    Hoch · CVSS 7.5EPSS 82,81%Korrektur verfügbar

    Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service

    Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.
