§ Q & A

February 2024 Patch Tuesday is feeling like a return to
normalcy. Microsoft has resolved 73 new CVEs, two of
which are confirmed Zero-day vulnerabilities. Most of
the risk this month can be wiped off your systems by
deploying the Windows OS updates, but there are
additional concerns to investigate in Windows AppX
Installer and Exchange Server.
For more details check out this month's Patch Tuesday
blog.

§ Attackers Exploit Microsoft Security-Bypass Zero-Day Bugs
§ Fat Patch Tuesday, February 2024 Edition
§ Microsoft Rolls Out Patches for 73 Flaws, Including 2 Windows Zero-Days

§ CVE-2024-21351 Windows Smartscreen Security Feature Bypass Vulnerability
§ CVSS 3.1 Scores: 7.6 / 6.6
§ Severity: Moderate
§ Impact: All Windows 10 operating systems and newer
§ Per Microsoft – The vulnerability allows a malicious actor to inject code into SmartScreen and
potentially gain code execution, which could potentially lead to some data exposure, lack of system
availability, or both. An attacker must send the user a malicious file and convince the user to open it.
Known Exploited Vulnerabilities

§ CVE-2024-21412 Internet Shortcut Files Security Bypass Vulnerability
§ CVSS 3.1 Scores: 8.1 / 7.1
§ Severity: Important
§ Impact: All Windows 10 operating systems and newer
§ Per Microsoft – An unauthenticated attacker could send the targeted user a specially crafted file that is
designed to bypass displayed security checks. However, the attacker would have no way to force a
user to view the attacker-controlled content. Instead, the attacker would have to convince them to take
action by clicking on the file link.
Known Exploited Vulnerabilities

CVE-2023-40547
§ CVSS 3: 9.8 (8.3 Red Hat)
§ Flaw in Shim (a small open-source bootloader
maintained by Red Hat)
§ Enables an attacker to craft a specific malicious
HTTP request, leading to a completely controlled
out-of-bounds write primitive and complete
system compromise.
Exploitation:
Only exploitable during early boot phase. An
attacker needs to perform a Man-in-the-Middle or
compromise the boot server to be able to exploit this
vulnerability successfully.
Five other vulnerabilities affecting Shim were
discovered this week:
CVE-2023-40551
CVE-2023-40550
CVE-2023-40549
CVE-2023-40548
CVE-2023-40546
New and Notable Linux Vulnerabilities: 1
Highlighted by TuxCare

CVE-2023-6780
§ CVSS 3: 9.8
§ glibc vulnerability that affects most distributions
out there.
§ It is possible to abuse a buffer to trigger
undefined behavior which can then further be
exploited to gain elevated privileges in a local
system.
Mitigation
This function is called by the syslog and vsyslog
functions. The problem happens when these
functions are called with a very long message,
causing an incorrect calculation of the buffer size to
store the message, resulting in the undefined
behavior.
How to Mitigate:
Upgrade glibc to version 2.39 or higher

CVE-2024-1086
§ CVSS 3: 7.8
§ Use-after-free that can lead to crashes or
undefined behavior
§ Found in the Netfilter subsystem in the Linux
kernel (concerning the firewall and packet
filtering) The nf_tables component can be
exploited to achieve local privilege escalation.
§ This bug happens in the "TO" module (one way
to perform packet redirection with netfilter),
which was found to contain a code-path with a
use-after-free bug.
Additional Context:
Netfilter enables various networking-related
operations to be implemented in the form of
customized handlers, providing functions and
operations for packet filtering, network address
translation, and port translation, which provide the
functionality required for directing packets through a
network and prohibiting packets from reaching
sensitive locations within a network.
Mitigation
Either prevent the affected Netfilter (“to(nf_tables)”)
kernel module from being loaded or disable user
namespaces.
