Detection & IOCsextracted from sources · hover to see the quote
- →Check for the 'Message Queuing' service running on the target host — its presence is a prerequisite for exploitability. ↗
- →Detect exposure by confirming TCP port 1801 is in a LISTEN state on Windows hosts; any such host reachable by unauthenticated network traffic is at risk of RCE. ↗
- →Exploitation requires no authentication — monitor for unexpected or anomalous inbound connections to TCP/1801 from untrusted sources. ↗
- ·MSMQ (Message Queuing service) is NOT enabled by default; systems are only exploitable if the feature has been explicitly added via Control Panel. ↗
- ·As of the advisory publication, no public exploit code exists and exploitation is rated 'Less Likely' by Microsoft. ↗

CVE-2023-36563 [CRITICAL] Microsoft patches 12 critical vulnerabilities, nine of which are in Layer 2 Tunneling Protocol
Microsoft disclosed 104 vulnerabilities in its extensive range of software and services, the most in a single Patch Tuesday since July.
What is most notable is that this batch of vulnerabilities includes 12 that are considered “critical,” nine of which are remote code execution vulnerabilities in the Layer 2 Tunneling Protocol.
Two other vulnerabilities that Microsoft is fixing Tuesday — CVE-2023-36563 in Microsoft WordPad and CVE-2023-41763 in the Skype communication platform — have already been publicly exploited in the wild and have proof-of-concept code available, making it more likely that attackers will try to exploit unpatched versions of these pieces of software. However, these issues are only considered “important.”

Twenty years ago this month, Microsoft introduced the concept of “Patch Tuesday” – although the marketing folks wanted it called “Update Tuesday” (they didn’t like the word “patch”). Over the years, more companies joined the Patch Tuesday bandwagon. Here we are 20 years later, still talking about the latest security releases from Adobe and Microsoft. Pop some champagne to celebrate and join us as we review the details of the latest advisories from Adobe and Microsoft. If you’d rather watch the video recap, you can check it out here.

CVE-2023-42724 [MEDIUM] Patch Tuesday, October 2023 Edition
Microsoft today issued security updates for more than 100 newly-discovered vulnerabilities in its Windows operating system and related software, including four flaws that are already being exploited. In addition, Apple recently released emergency updates to quash a pair of zero-day bugs in iOS.
Apple last week shipped emergency updates in iOS 17.0.3 and iPadOS 17.0.3 in response to active attacks. The patch fixes CVE-2023-42724, which attackers have been using in targeted attacks to elevate their access on a local device.
Apple said it also patched CVE-2023-5217, which is not listed as a zero-day bug. However, as Bleeping Computer pointed out, this flaw is caused by a weakness in the open-source “libvpx” video codec library, which was previously patched as a zero-day flaw by Google in th
