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

Qualys discovered a vulnerability in OpenSMTPD, OpenBSD's mail server. This vulnerability is exploitable since May 2018 (commit a8e222352f, "switch smtpd to new grammar") and allows an attacker to execute arbitrary shell commands, as root.

Microsoft Windows SMB version 3.1.1 suffers from a code execution 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.

This Metasploit module exploits an authentication bypass vulnerability on Avaya IP Office Customer Call Reporter, which allows a remote user to upload arbitrary files through the ImageUpload.ashx component. It can be abused to upload and execute arbitrary ASP .NET code. The vulnerability has been tested successfully on Avaya IP Office Customer Call Reporter 7.0.4.2 and 8.0.8.15 on Windows 2003 SP2.

LW-N605R devices allow remote code execution via shell metacharacters in the HOST field of the ping feature at adm/systools.asp. Authentication is needed but the default password of admin for the admin account may be used in some cases.

The ZyXEL P-660HN-T1 V2 rpWLANRedirect.asp page is missing authentication and discloses an administrator password.

The Telerik UI for ASP.NET AJAX insecurely deserializes JSON objects in a manner that results in arbitrary remote code execution on the software's underlying host.
