October Patch Tuesday harvest hauls in 117 CVEs – Sophos Information

Microsoft on Tuesday launched 117 patches touching 15 product households. Three of the addressed points, affecting Configuration Supervisor, Visible Studio, and Home windows, are thought-about by Microsoft to be of Vital severity. At launch time, two of the problems addressed are identified to be underneath exploit within the wild, with eight extra CVEs extra prone to be exploited within the subsequent 30 days by the corporate’s estimation. Three of this month’s points are amenable to detection by Sophos protections, and we embody info on these in a desk beneath.

Along with these patches, the discharge contains advisory info on 4 Edge-related CVEs and one associated to curve (affecting CBL Mariner and Home windows), together with the standard servicing stack updates. We’re as at all times together with on the finish of this submit extra appendices itemizing all Microsoft’s patches, sorted by severity, by predicted exploitability, and by product household.

Notable October updates

Along with the problems mentioned above, quite a lot of particular objects benefit consideration.

CVE-2024-38124 – Home windows Netlogon Elevation of Privilege Vulnerability
CVE-2024-43468 — Microsoft Configuration Supervisor Distant Code Execution Vulnerability

Each of this month’s CVEs with CVSS base scores of 9.0 or above include mitigation recommendation. The Config Supervisor difficulty (CVE-2024-43468), the extra extreme of the 2 with a 9.8 CVSS, additionally has particular directions. For the Netlogon difficulty (CVE-2024-38124), the next mitigations are provided (textual content courtesy of Microsoft):

• Predictable Naming Conventions: Keep away from utilizing predictable naming conventions for area controllers to forestall attackers from renaming their machines to match the subsequent identify to be assigned to a brand new area controller.
• Safe Channel Validation: Be certain that the safe channel is validated in opposition to extra than simply the pc identify of the machine it was delivered to. This may also help forestall attackers from impersonating the area controller by acquiring the deal with and ready for the appointment to occur.
• Monitor for Renaming Actions: Implement monitoring for any suspicious renaming actions of computer systems inside the community. This may also help with early detection and prevention of potential assaults.
• Enhanced Authentication Mechanisms: Think about using enhanced authentication mechanisms that transcend the present validation strategies to make sure the authenticity of the area controller and the safe channel.

As for the Configuration Supervisor difficulty, there are further steps required (textual content, once more, courtesy of Microsoft):

Prospects utilizing a model of Configuration Supervisor specified within the Safety Updates desk of this CVE want to put in an in-console replace to be protected. Steering for the way to set up Configuration Supervisor in-console updates is out there right here: Set up in-console updates for Configuration Supervisor.

The mitigation steerage for the Configuration Supervisor difficulty additionally recommends that directors specify an alternate service account, slightly than the Laptop account; extra info is out there right here.

[15 CVEs] – Home windows Cellular Broadband Driver DoS and RCE points

None of those points are as regarding because the Vital-severity CVE-2024-38161 cell broadband driver difficulty patched again in July, however the sheer quantity is outstanding, as is the truth that all of those require bodily entry (to plug in a USB drive) or proximity (enough for radio transmission).

CVE-2024-43485 — .NET and Visible Studio Denial of Service Vulnerability

This Vital-severity Denial of Service difficulty casts its .web slightly extensively, affecting the platform not solely on Home windows however on Linux and macOS.

CVE-2024-43497 — DeepSpeed Distant Code Execution Vulnerability

It’s not widespread for a Low-severity difficulty to be named within the Patch Tuesday launch, however this one’s attention-grabbing for one more cause – it impacts DeepSpeed, Microsoft’s speed-and-scale optimization booster for deep-learning coaching. (We consider this to be the first-ever Patch Tuesday bug affecting DeepSpeed, in addition to the primary Microsoft discover credited to an AI-specific bug-bounty program.)

CVE-2024-43527 — Home windows Kernel Elevation of Privilege Vulnerability
CVE-2024-43571 — Sudo for Home windows Spoofing Vulnerability

These two patches are much less notable for what they’re (although some observers could also be startled to see discuss of sudo in a Patch Tuesday submit) than for what model of Home windows they have an effect on.  Each of those Vital-severity patches have an effect on solely Home windows 11 24H2, the OS model coming into common launch this week.

CVE-2024-43573 — Home windows MSHTML Platform Spoofing Vulnerability

One of many two vulnerabilities identified to be underneath lively exploit within the wild, this Average-severity Spoofing difficulty will get into the Halloween spirit by invoking the ghost of Web Explorer. Prospects who obtain Safety Solely updates are inspired to use the IE Cumulative updates to exorcise this vulnerability.

Determine 3: As we enter the final quarter of the 12 months, Denial of Service points are catapulted into third place on the leaderboard, whereas the DeepSpeed bug places a Low-severity patch on the board for the primary time in 2024

Sophos protections

As you possibly can each month, in the event you don’t need to wait to your system to drag down Microsoft’s updates itself, you possibly can obtain them manually from the Home windows Replace Catalog web site. Run the winver.exe software to find out which construct of Home windows 10 or 11 you’re working, then obtain the Cumulative Replace package deal to your particular system’s structure and construct quantity.
