- CVE-2024-21351 (CVSS score: 7.6) – Windows SmartScreen Security Characteristic Bypass Vulnerability
- CVE-2024-21412 (CVSS rating: 8.1) – Internet Shortcut Files Security Aspect Bypass Vulnerability
“The vulnerability lets a malicious actor to inject code into SmartScreen and likely attain code execution, which could perhaps lead to some info exposure, absence of program availability, or each,” Microsoft said about CVE-2024-21351.
Successful exploitation of the flaw could allow for an attacker to circumvent SmartScreen protections and run arbitrary code. Nevertheless, for the attack to perform, the danger actor will have to ship the person a destructive file and convince the user to open up it.
CVE-2024-21412, in a comparable fashion, permits an unauthenticated attacker to bypass displayed security checks by sending a specially crafted file to a focused consumer.
“On the other hand, the attacker would have no way to power a consumer to watch the attacker-controlled content material.” Redmond noted. “As a substitute, the attacker would have to influence them to just take motion by clicking on the file link.”
CVE-2024-21351 is the second bypass bug to be learned in SmartScreen after CVE-2023-36025 (CVSS score: 8.8), which was plugged by the tech giant in November 2023. The flaw has due to the fact been exploited by various hacking groups to proliferate DarkGate, Phemedrone Stealer, and Mispadu.
Development Micro, which thorough an attack marketing campaign undertaken by H2o Hydra (aka DarkCasino) focusing on economic market traders by implies of a refined zero-day attack chain leveraging CVE-2024-21412, described CVE-2024-21412 as a bypass for CVE-2023-36025, thus enabling danger actors to evade SmartScreen checks.
H2o Hydra, initial detected in 2021, has a keep track of report of launching attacks from banking companies, cryptocurrency platforms, trading products and services, gambling web pages, and casinos to provide a trojan called DarkMe applying zero-day exploits, such as the WinRAR flaw that arrived to gentle in August 2023 (CVE-2023-38831, CVSS rating: 7.8).
Late previous year, Chinese cybersecurity enterprise NSFOCUS graduated the “economically inspired” hacking group to an solely new sophisticated persistent threat (APT).
“In January 2024, Drinking water Hydra updated its an infection chain exploiting CVE-2024-21412 to execute a destructive Microsoft Installer File (.MSI), streamlining the DarkMe infection process,” Pattern Micro mentioned.
Both vulnerabilities have given that been extra to the Regarded Exploited Vulnerabilities (KEV) catalog by the U.S. Cybersecurity and Infrastructure Security Company (CISA), urging federal agencies to implement the latest updates by March 5, 2024.
Also patched by Microsoft are five critical flaws –
- CVE-2024-20684 (CVSS score: 6.5) – Windows Hyper-V Denial of Service Vulnerability
- CVE-2024-21357 (CVSS score: 7.5) – Windows Pragmatic Standard Multicast (PGM) Remote Code Execution Vulnerability
- CVE-2024-21380 (CVSS rating: 8.) – Microsoft Dynamics Business Central/NAV Information Disclosure Vulnerability
- CVE-2024-21410 (CVSS rating: 9.8) – Microsoft Trade Server Elevation of Privilege Vulnerability
- CVE-2024-21413 (CVSS rating: 9.8) – Microsoft Outlook Distant Code Execution Vulnerability
“CVE-2024-21410 is an elevation of privilege vulnerability in Microsoft Trade Server,” Satnam Narang, senior staff exploration engineer at Tenable, said in a assertion. “This flaw is more likely to be exploited by attackers according to Microsoft.”
“Exploiting this vulnerability could result in the disclosure of a focused user’s Net-New Technology LAN Manager (NTLM) variation 2 hash, which could be relayed back again to a vulnerable Trade Server in an NTLM relay or pass-the-hash attack, which would allow the attacker to authenticate as the focused person.”
The security update even more resolves 15 remote code execution flaws in Microsoft WDAC OLE DB company for SQL Server that an attacker could exploit by tricking an authenticated person into making an attempt to connect to a destructive SQL server by way of OLEDB.
Rounding off the patch is a correct for CVE-2023-50387 (CVSS rating: 7.5), a 24-calendar year-aged structure flaw in the DNSSEC specification that can be abused to exhaust CPU methods and stall DNS resolvers, resulting in a denial-of-service (DoS).
The vulnerability has been codenamed KeyTrap by the Countrywide Investigate Center for Used Cybersecurity (ATHENE) in Darmstadt.
“They demonstrated that just with a single DNS packet the attack can exhaust the CPU and stall all broadly employed DNS implementations and community DNS companies, this sort of as Google General public DNS and Cloudflare,” the researchers explained. “In point, the preferred BIND 9 DNS implementation can be stalled for as very long as 16 several hours.”
