Bro is a powerful network analysis framework that is much different from the typical IDS you may know. While focusing on network security monitoring, Bro provides a comprehensive platform for more general network traffic analysis as well. Well grounded in more than 15 years of research, Bro has successfully bridged the traditional gap between academia and operations since its inception. Today, it is relied upon operationally in particular by many scientific environments for securing their cyber-infrastructure. Bro's user community includes major universities, research labs, supercomputing centers, and open-science communities.

Qualys has discovered that OpenBSD suffers from multiple authentication bypass and local privilege escalation vulnerabilities.

Qualys discovered a local privilege escalation in OpenBSD's dynamic loader (ld.so). This vulnerability is exploitable in the default installation (via the set-user-ID executable chpass or passwd) and yields full root privileges. They developed a simple proof of concept and successfully tested it against OpenBSD 6.6 (the current release), 6.5, 6.2, and 6.1, on both amd64 and i386; other releases and architectures are probably also exploitable.

Deep Instinct Windows Agent version 1.2.29.0 suffers from an unquoted service path vulnerability.

The Windows "net use" network logon type-3 command does not prompt for authentication when the built-in Administrator account is enabled and both remote and originating systems suffer from password reuse. This also works as "standard" user but unfortunately we do not gain high integrity privileges. However, it opens the door and increases the attack surface if the box we laterally move to has other vulnerabilities present.

Microsoft Windows suffers from an NtFilterToken ParentTokenId incorrect setting that allows for elevation of privileges.

In Microsoft Windows, by using the poorly documented SE_SERVER_SECURITY Control flag it is possible to set an owner different to the caller, bypassing security checks.

This Metasploit module exploits a logic flaw due to how the lpApplicationName parameter is handled. When the lpApplicationName contains a space, the file name is ambiguous. Take this file path as example: C:program fileshello.exe; The Windows API will try to interpret this as two possible paths: C:program.exe, and C:program fileshello.exe, and then execute all of them. To some software developers, this is an unexpected behavior, which becomes a security problem if an attacker is able to place a malicious executable in one of these unexpected paths, sometimes escalate privileges if run as SYSTEM. Some software such as OpenVPN 2.1.1, OpenSSH Server 5, and others have the same problem.
