IMAP APPEND plus CRLF conversion command injection

Enabling CURLOPTCRLF causes curl to advertise the raw input byte count in the IMAP APPEND N literal while transmitting line-ending expanded data. The server reads only $N$ bytes for the payload, causing the remaining overflow bytes to be interpreted and executed as pipelined IMAP commands within...

Astra Linux – Vulnerability in Waitress

Waitress version 1.3.1 would parse the Transfer-Encoding header and only look for a single string value. If that value was not in the “chunked” format, it would proceed using the Content-Length header instead. According to the HTTP standard, Transfer-Encoding should be a comma-separated list, wit...

Astra Linux – Vulnerability in Twisted

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

Astra Linux – Vulnerability in Twisted

Twisted is an event-based framework for internet applications, compatible with Python 3.6+. The HTTP 1.0 and 1.1 server provided by twisted.web could process pipelined HTTP requests out-of-order, potentially leading to information disclosure. This vulnerability has been fixed in 24.7.0rc1...

netty: io.netty/netty-codec-http: Netty: Incorrect HTTP response parsing leads to data confusion

A flaw was found in Netty, an asynchronous, event-driven network application framework. A remote attacker could exploit this vulnerability by sending a specific sequence of HTTP responses 103, followed by a 200 with a GET body, then another 200 for a HEAD request when the client pipelines GET the...

GHSA-W6F5-V2H6-G786 Predis: Redis command injection and denial of service via CRLF smuggling in pipelined commands on aggregate connections

Summary An improper CRLF neutralization flaw in Predis' pipeline handling on aggregate connections lets an unauthenticated attacker who can influence any pipelined argument — a value or a key, e.g. a URL slug used as a cache key — smuggle arbitrary Redis commands into the connection. - On cluster...

Denial-of-service (DoS)

io.projectreactor.netty, reactor-netty-http is vulnerable to a denial-of-service DoS. The vulnerability is due to improper handling of multiple pipelined HTTP/1.1 requests over a single connection, which allows an attacker to send specially crafted requests that consume excessive memory and...
