CVE-2020-12271: Sophos XG Firewall Pre-Auth SQL Injection Vulnerability Remediation Guidance and Exposure Overview

blog.rapid7.com/2020/04/27/cve-2020-12271-sophos-xg-firewall-pre-auth-sql-injection-vulnerability-remediation-guidance-and-exposure-overview/ We crafted a lightweight study (a more thorough one is in the works) to grab any accessible user and/or admin pages from the discovered nodes and extract that ver= build string.

What’s next?. The Rapid7 Labs team is refining the Sophos version identification studies and will continue to monitor Project Heisenberg for opportunistic exploitation attempts. We’ll update this blog post as more information surfaces. Again, any service provider or individual organization running a Sophos XG appliance should remediate as quickly as possible.

Ad Hoc or Managed Penetration Testing: Which One Is Best for You?

securityintelligence.com/posts/ad-hoc-or-managed-penetration-testing-which-one-is-best-for-you/ Penetration testing is no longer an extraordinary security engagement. Due to regulatory mandates, internal policies, business executive requests and the overall desire to avoid becoming the next breach victim, testing is now commonplace among many organizations. The kind of testing, however, can still be a question. Do you need ad hoc testing, that as-needed affair that takes place once or twice a year? Or do you need a managed testing program that is continual and coordinated by an outside testing team?

Any new multimedia file — image, audio, video — that reaches a device is automatically transferred to a local OS library that parses the file to know what it is and what to do with it next.
