An issue was discovered in Python before 3.8.18, 3.9.x before 3.9.18, 3.10.x before 3.10.13, and 3.11.x before 3.11.5. It primarily affects servers (such as HTTP servers) that use TLS client authentication. If a TLS server-side socket is created, receives data into the socket buffer, and then is closed quickly, there is a brief window where the SSLSocket instance will detect the socket as "not connected" and won't initiate a handshake, but buffered data will still be readable from the socket buffer. This data will not be authenticated if the server-side TLS peer is expecting client certificate authentication, and is indistinguishable from valid TLS stream data. Data is limited in size to the amount that will fit in the buffer. (The TLS connection cannot directly be used for data exfiltration because the vulnerable code path requires that the connection be closed on initialization of the SSLSocket.)
When this crate is given a pathological certificate chain to validate, it will spend CPU time exponential with the number of candidate certificates at each step of path building. Both TLS clients and TLS servers that accept client certificate are affected. This was previously reported in <https://github.com/briansmith/webpki/issues/69> and re-reported recently by Luke Malinowski. `rustls-webpki` is a fork of this crate which contains a fix for this issue and is actively maintained.
### During startup, an attacker that can man-in-the-middle traffic to and from NTS key exchange servers can trigger a very expensive key validation process due to a vulnerability in webpki. ### Impact This vulnerability can lead to excessive cpu usage on startup on clients configured to use NTS ### Patches Affected users are recommended to upgrade to version 0.3.7 ### References See also https://github.com/rustsec/advisory-db/blob/main/crates/rustls-webpki/RUSTSEC-2023-0053.md

This Metasploit module exploits an unauthenticated remote command execution vulnerability that affects Chamilo versions 1.11.18 and below. Due to a functionality called Chamilo Rapid to easily convert PowerPoint slides to courses on Chamilo, it is possible for an unauthenticated remote attacker to execute arbitrary commands at the OS level using a malicious SOAP request at the vulnerable endpoint /main/webservices/additional_webservices.php.

Lazarus Group appears to be changing its tactics, increasingly relying on open-source tools and frameworks in the initial access phase of their attacks, as opposed to strictly employing them in the post-compromise phase.
Public Wi-Fi, which has long since become the norm, poses threats to not only individual users but also businesses. With the rise of remote work, people can now work from virtually anywhere: a cafe close to home, a hotel in a different city, or even while waiting for a plane at the airport. Next, let's explore the risks of connecting to public Wi-Fi, both for you personally and for businesses.
