DISPUTED A segmentation fault can occur in the sqlite3.exe command-line component of SQLite 3.36.0 via the idxGetTableInfo function when there is a crafted SQL query. NOTE: the vendor disputes the relevance of this report because a sqlite3.exe user already has full privileges (e.g., is intentionally allowed to execute commands). This report does NOT imply any problem in the SQLite library.
A denial of service via regular expression in the py.path.svnwc component of py (aka python-py) through 1.9.0 could be used by attackers to cause a compute-time denial of service attack by supplying malicious input to the blame functionality.
ModSecurity 3.x through 3.0.5 mishandles excessively nested JSON objects. Crafted JSON objects with nesting tens-of-thousands deep could result in the web server being unable to service legitimate requests. Even a moderately large (e.g., 300KB) HTTP request can occupy one of the limited NGINX worker processes for minutes and consume almost all of the available CPU on the machine. Modsecurity 2 is similarly vulnerable: the affected versions include 2.8.0 through 2.9.4.
The Twisted Web HTTP 1.1 server, located in the twisted.web.http module, parsed several HTTP request constructs more leniently than permitted by RFC 7230:
1. The Content-Length header value could have a + or - prefix. 2. Illegal characters were permitted in chunked extensions, such as the LF (\n) character. 3. Chunk lengths, which are expressed in hexadecimal format, could have a prefix of 0x. 4. HTTP headers were stripped of all leading and trailing ASCII whitespace, rather than only space and HTAB (\t).
This non-conformant parsing can lead to desync if requests pass through multiple HTTP parsers, potentially resulting in HTTP request smuggling.
Impact
You may be affected if:
1. You use Twisted Web's HTTP 1.1 server and/or proxy 2. You also pass requests through a different HTTP server and/or proxy
The specifics of the other HTTP parser matter. The original report notes that some versions of Apache Traffic Server and HAProxy have been vulnerable in the past. HTTP request smuggling may be a serious concern if you use a proxy to perform request validation or access control.
The Twisted Web client is not affected. The HTTP 2.0 server uses a different parser, so it is not affected.
Patches
The issue has been addressed in Twisted 22.4.0rc1 and later.
Workarounds
Other than upgrading Twisted, you could:
Ensure any vulnerabilities in upstream proxies have been addressed, such as by upgrading them Filter malformed requests by other means, such as configuration of an upstream proxy
Credits
This issue was initially reported by Zhang Zeyu.
Impact
The Twisted SSH client and server implementation naively accepted an infinite amount of data for the peer's SSH version identifier.
A malicious peer can trivially craft a request that uses all available memory and crash the server, resulting in denial of service. The attack is as simple as nc -rv localhost 22 < /dev/zero.
Patches
The issue was fix in GitHub commit https://github.com/twisted/twisted/commit/98387b39e9f0b21462f6abc7a1325dc370fcdeb1
A fix is available in Twisted 22.2.0.
Workarounds
Limit access to the SSH server only to trusted source IP addresses. Connect over SSH only to trusted destination IP addresses.
