Cybersecurity researchers have lifted the lid on a previously undocumented threat cluster dubbed GhostRedirector that has managed to compromise at least 65 Windows servers primarily located in Brazil, Thailand, and Vietnam. The attacks, per Slovak cybersecurity company ESET, led to the deployment of a passive C++ backdoor called Rungan and a native Internet Information Services (IIS) module

## Summary A flaw in netty's parsing of chunk extensions in HTTP/1.1 messages with chunked encoding can lead to request smuggling issues with some reverse proxies. ## Details When encountering a newline character (LF) while parsing a chunk extension, netty interprets the newline as the end of the chunk-size line regardless of whether a preceding carriage return (CR) was found. This is in violation of the HTTP 1.1 standard which specifies that the chunk extension is terminated by a CRLF sequence (see the [RFC](https://datatracker.ietf.org/doc/html/rfc9112#name-chunked-transfer-coding)). This is by itself harmless, but consider an intermediary with a similar parsing flaw: while parsing a chunk extension, the intermediary interprets an LF without a preceding CR as simply part of the chunk extension (this is also in violation of the RFC, because whitespace characters are not allowed in chunk extensions). We can use this discrepancy to construct an HTTP request that the intermediary will ...

### Description When the Vaadin Upload's start listener is used to validate metadata about an incoming upload, it is possible to bypass the upload validation. Users of affected versions should apply the upgrade to a more recent Vaadin version.

### Impact The verification of the second factor had too long a session expiry. The long session expiry could be used to circumvent rate limiting of the second factor. ### Patches This issue has been addressed in Weblate 5.13.1 via https://github.com/WeblateOrg/weblate/pull/16002. ### References Thanks to Nahid Hasan Limon for reporting this issue responsibly.

Kaleo Forms Admin in Liferay Portal 7.0.0 through 7.4.3.4, and Liferay DXP 7.4 GA, 7.3 GA through update 27, and older unsupported versions does not restrict the saving of request parameters in the portlet session, which allows remote attackers to consume system memory leading to denial-of-service (DoS) conditions via crafted HTTP request.
