CVE-2021-43802 Admin privilege escalation and arbitrary code execution via malicious *.etherpad imports

Etherpad is a real-time collaborative editor. In versions prior to 1.8.16, an attacker can craft an .etherpad file that, when imported, might allow the attacker to gain admin privileges for the Etherpad instance. This, in turn, can be used to install a malicious Etherpad plugin that can execute...

ruby: Potential HTTP request smuggling in WEBrick

An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy which also has a po...

The vulnerability of reverse proxies and proxy redirection mechanisms in the Apache Traffic Server allows attackers to gain access to confidential data, compromise its integrity, and cause service failures.

The vulnerability of reverse proxies and proxy redirection in the Apache Traffic Server is related to inconsistent interpretation of HTTP requests. Exploiting this vulnerability can allow a remote attacker to access sensitive data, compromise its integrity, and cause service failures...

The vulnerability of reverse proxies and proxy redirection mechanisms in the Apache Traffic Server allows attackers to induce service failures.

The vulnerability of reverse proxies and proxy redirection in the Apache Traffic Server is related to uncontrolled resource consumption. Exploiting this vulnerability can allow a malicious actor to cause service interruptions...

The vulnerability of reverse proxies and proxy redirection mechanisms in the Apache Traffic Server, related to the operation exceeding the allowed buffer data limits, allows attackers to cause service failures.

CVE-2019-12520

A flaw was found in squid. The absolute URL of a request can include the decoded UserInfo username and password for certain protocols. This decoded info may contain special characters to delimit the domain, and treat the rest of the URL as a path or query string. An attacker could first make a...

CVE-2019-12520

An issue was discovered in Squid through 4.7 and 5. When receiving a request, Squid checks its cache to see if it can serve up a response. It does this by making a MD5 hash of the absolute URL of the request. If found, it servers the request. The absolute URL can include the decoded UserInfo...

GHSA-4PPP-GPCR-7QF6 HTTP Request Smuggling: Content-Length Sent Twice in Waitress

Impact Waitress would header fold a double Content-Length header and due to being unable to cast the now comma separated value to an integer would set the Content-Length to 0 internally. So a request with: Content-Length: 10 Content-Length: 10 would get transformed to: Content-Length: 10, 10 Whic...

HTTP Request Smuggling: Invalid Transfer-Encoding in Waitress

Impact Waitress would parse the Transfer-Encoding header and only look for a single string value, if that value was not chunked it would fall through and use the Content-Length header instead. According to the HTTP standard Transfer-Encoding should be a comma separated list, with the inner-most...

GHSA-PG36-WPM5-G57P HTTP Request Smuggling: LF vs CRLF handling in Waitress

Impact Waitress implemented a "MAY" part of the RFC7230 https://tools.ietf.org/html/rfc7230section-3.5 which states: Although the line terminator for the start-line and header fields is the sequence CRLF, a recipient MAY recognize a single LF as a line terminator and ignore any preceding CR...

A poorly-behaved client could use keepalive requests to monopolize Puma's reactor and create a denial of service attack

Keepalive thread overload/DoS Impact A poorly-behaved client could use keepalive requests to monopolize Puma's reactor and create a denial of service attack. If more keepalive connections to Puma are opened than there are threads available, additional connections will wait permanently if the...

http-traceroute NSE Script
