Synopsis
The remote Amazon Linux 2023 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-056 advisory.A flaw was found in the twisted Python library when WebClient redirects via the RedirectAgent and BrowserLikeRedirectAgent methods. This flaw allows an attacker to take advantage of these cross-origin redirects and leak the cookie and authorization headers. (CVE-2022-21712)
An uncontrolled resource consumption flaw was found in python-twisted in the dataReceived() function. This flaw allows an unauthenticated, remote attacker to send a simple command to use all available memory and crash the server. (CVE-2022-21716)
A flaw was found in python-twisted. This vulnerability occurs due to the parsing of illegal constructs in the twisted.web.http module. The illegal constructs include '+/-' in the Content-Length header, '\n and \t' etc. Non-conformant parsing leads to a desync if requests pass through multiple HTTP parsers. This flaw allows a remote attacker to perform an HTTP request smuggling attack. (CVE-2022-24801)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
