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 recognized to be beneath exploit within the wild, with eight further CVEs extra more likely 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 under.

Along with these patches, the discharge contains advisory info on 4 Edge-related CVEs and one associated to twist (affecting CBL Mariner and Home windows), together with the standard servicing stack updates. We’re as all the time together with on the finish of this put up further 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, numerous particular objects advantage 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 challenge (CVE-2024-43468), the extra extreme of the 2 with a 9.8 CVSS, additionally has particular directions. For the Netlogon challenge (CVE-2024-38124), the next mitigations are supplied (textual content courtesy of Microsoft):

• Predictable Naming Conventions: Keep away from utilizing predictable naming conventions for area controllers to stop attackers from renaming their machines to match the subsequent title to be assigned to a brand new area controller.
• Safe Channel Validation: Be sure that the safe channel is validated towards extra than simply the pc title of the machine it was delivered to. This might help stop 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 might 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 challenge, there are further steps required (textual content, once more, courtesy of Microsoft):

Clients 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. Steerage for learn how to set up Configuration Supervisor in-console updates is accessible right here: Set up in-console updates for Configuration Supervisor.

The mitigation steering for the Configuration Supervisor challenge additionally recommends that directors specify an alternate service account, somewhat than the Pc account; extra info is accessible right here.

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

None of those points are as regarding because the Vital-severity CVE-2024-38161 cellular broadband driver challenge 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 (adequate for radio transmission).

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

This Essential-severity Denial of Service challenge casts its .internet somewhat broadly, affecting the platform not solely on Home windows however on Linux and macOS.

CVE-2024-43497 — DeepSpeed Distant Code Execution Vulnerability

It’s not frequent for a Low-severity challenge to be named within the Patch Tuesday launch, however this one’s fascinating for one more purpose – 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 put up) than for what model of Home windows they have an effect on.  Each of those Essential-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 recognized to be beneath energetic exploit within the wild, this Average-severity Spoofing challenge will get into the Halloween spirit by invoking the ghost of Web Explorer. Clients 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 yr, 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, if you happen to don’t need to wait on your system to tug down Microsoft’s updates itself, you possibly can obtain them manually from the Home windows Replace Catalog web site.
