Microsoft, Late to the Game on Dangerous DNSSEC Zero-Day Flaw

Why the company took so long to address the issue is not known given that most other stakeholders had a fix out for the issue months ago.

Telerik Report Server Authentication Bypass / Remote Code Execution

This Metasploit module chains an authentication bypass vulnerability with a deserialization vulnerability to obtain remote code execution against Telerik Report Server versions 10.0.24.130 and below. The authentication bypass flaw allows an unauthenticated user to create a new user with administrative privileges. The USERNAME datastore option can be used to authenticate with an existing account to prevent the creation of a new one. The deserialization flaw works by uploading a specially crafted report that when loaded will execute an OS command as NT AUTHORITY\SYSTEM. The module will automatically delete the created report but not the account because users are unable to delete themselves.

Cacti Import Packages Remote Code Execution

This exploit module leverages an arbitrary file write vulnerability in Cacti versions prior to 1.2.27 to achieve remote code execution. It abuses the Import Packages feature to upload a specially crafted package that embeds a PHP file. Cacti will extract this file to an accessible location. The module finally triggers the payload to execute arbitrary PHP code in the context of the user running the web server. Authentication is needed and the account must have access to the Import Packages feature. This is granted by setting the Import Templates permission in the Template Editor section.

Ubuntu Security Notice USN-6819-3

Ubuntu Security Notice 6819-3 - Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service. Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of-bounds read vulnerability. An attacker could use this to possibly cause a denial of service.

Cybercriminals Employ PhantomLoader to Distribute SSLoad Malware

The nascent malware known as SSLoad is being delivered by means of a previously undocumented loader called PhantomLoader, according to findings from cybersecurity firm Intezer. "The loader is added to a legitimate DLL, usually EDR or AV products, by binary patching the file and employing self-modifying techniques to evade detection," security researchers Nicole Fishbein and Ryan Robinson said in
