Of the seven critical flaws, five allow for remote code execution (RCE) and two give attackers elevation of privilege (EoP). The remainder of the flaws also include a high percentage of RCE and EoP bugs, with the former accounting for 32.9 percent of the flaws patched this month, while the latter accounted for 28.8 percent of fixes, according to a blog post by researchers at Tenable.
Customers with Microsoft Defender Antivirus (MDAV) should turn-on cloud-delivered protection and automatic sample submission. These capabilities use artificial intelligence and machine learning to quickly identify and stop new and unknown threats.
Falcon Spotlight ExPRT. AI can help staff identify which vulnerabilities are truly relevant for their organizations to address immediately. Falcon Spotlight, coupled with Falcon Identity Protection, offers robust visibility to stop threats in their tracks. The following updates cover two remote code execution vulnerabilities and one elevation of privilege vulnerability. It is worth noting that CVE-2022-21984 and CVE-2022-22005 are on critical systems and even a short exposure for an organization may yield severe outcomes if not mitigated or patched promptly.
In addition to SAP's June security updates, Onapsis researchers said they detected miscreants exploiting three vulnerabilities that SAP already patched: CVE-2021-38163, CVE-2016-2386, and CVE-2016-2388.
The networking firm also patched a denial of service vulnerability in the software-based SSL/TLS message handler of Cisco Firepower Threat Defense (FTD) Software. This high-severity flaw could be exploited by an unauthenticated, remote attacker by sending a crafted SSL/TLS message through an affected device, thus crashing the process and triggering a reload of the device, according to Cisco. ®
Please Note: Microsoft Exchange is not patched by the Windows Update process. In order to update/patch Exchange Servers, please consult the Microsoft Exchange blog.
TuxCare automatically delivers the latest CVE patches on all popular Linux distributions without needing to reboot the kernel, so your team never needs to restart systems or wait for scheduled maintenance windows to apply a vulnerability patch.
Conventional vulnerability patching often requires IT teams to reboot the Linux kernel to apply patches, but not with TuxCare. Our live patching solutions deploy patches in memory while the kernel is running, so you can patch all popular enterprise Linux distributions, databases, shared libraries and more without needing to reboot or schedule downtime.
The Windows versions impacted by the vulnerability are widely used by corporate networks and their employees. If not patched, threat actors can generate malicious Office and RTF documents, as well as CAB files to remotely execute commands on a target system. A victimized remote worker who uses Windows 10, or a vendor who uses Windows 2008 R2, may cause a data breach and/or a ransomware attack by simply opening a Word document.
No need to install software on premises or configure open ports and VPNs. Any on-premises workstation and server, or work-from-home (WFH) device with the Qualys Cloud Agent installed can be immediately scanned for missing patches and patched. Anywhere you can put the Qualys Cloud Agent, you can run Qualys Patch Management. When Qualys Patch Management is used with the Qualys Cloud Agent Gateway Service, you can significantly optimize bandwidth usage by caching patches locally on your network.
With remote work now the norm, many organizations struggle to deliver patches to corporate and personal devices when users are working from home or otherwise infrequently connected to the network. Qualys Patch Management allows the patch team to deliver patches to these remote users within hours from the cloud, while avoiding the use of limited VPN bandwidth.
Microsoft has released patches for 84 vulnerabilities in its products on its monthly Patch Tuesday, but failed to deliver fixes for two zero-day flaws in versions of Exchange Server that were reported publicly on 29 September.
"Microsoft patched CVE-2022-41033, an elevation of privilege vulnerability in the Windows COM+ Event System Service, which enables system event notifications for COM+ components. An authenticated attacker could execute a specially crafted application designed to exploit this vulnerability on a vulnerable system.
Like all maintenance updates, the patches delivered by Live Patching are delivered as signed RPMs. Introducing the solution into your established administrative process is simple because you can reuse existing deployment methods, including YaST, zypper, and SUSE Manager.
This SCCM patch management step-by-step guide covers all the steps required to deploy the updates to production machines. To stay protected against cyber-attacks and malicious threats, you must keep the computers patched with latest software updates.
Database, Fusion Middleware, and Oracle Enterprise Manager products are patched in accordance with the Software Error Correction Support Policy explained in My Oracle Support Note 209768.1. Please review the Technical Support Policies for further guidelines regarding support policies and phases of support.
For Metasploit, we will use a post module to find missing patches. With WMIC, we will run commands directly from a shell on the system to view quick fix engineering patches. And using Windows Exploit Suggester, we will compare the installed patches on the system with a database of vulnerabilities. We will be using Kali Linux to attack an unpatched version of Windows 7.
The average time between disclosure and patch availability was approximately 9 days. This average is slightly inflated by vulnerabilities such as CVE-2019-0863, a Microsoft Windows server vulnerability, which was disclosed in December 2018 and not patched until 5 months later in May 2019. The majority of these vulnerabilities, however, were patched quickly after disclosure. In 59% of cases, a patch was released on the same day the vulnerability was disclosed. These metrics, in combination with the observed swiftness of adversary exploitation activity, highlight the importance of responsible disclosure, as it may provide defenders with the slim window needed to successfully patch vulnerable systems.
FireEye judges that malicious actors are likely to most frequently leverage vulnerabilities based on a variety of factors that influence the utility of different vulnerabilities to their specific operations. For instance, we believe that attackers are most likely to target the most widely used products (see Figure 6). Attackers almost certainly also consider the cost and availability of an exploit for a specific vulnerability, the perceived success rate based on the delivery method, security measures introduced by vendors, and user awareness around certain products.
The speed with which attackers exploit patched vulnerabilities emphasizes the importance of patching as quickly as possible. With the sheer quantity of vulnerabilities disclosed each year, however, it can be difficult for organizations with limited resources and business constraints to implement an effective strategy for prioritizing the most dangerous vulnerabilities. In upcoming blog posts, FireEye Mandiant Threat Intelligence describes our approach to vulnerability risk rating as well as strategies for making informed and realistic patch management decisions in more detail.
Welcome to my January Patch Tuesday newsletter. We are starting off 2023 with a large quantity of patches. There are 103 vulnerabilities being addressed this month with 11 of them being rated as critical (bold in the chart below). There is one zero-day being address, CVE-2023-21549, highlighted in yellow below. Microsoft reports that exploiting this vulnerability could allow an attacker to execute RPC functions that are restricted to privileged accounts. Despite the existance of various reports online that this shouldn't be listed as publicly disclosed we do hope you make sure this one gets patched. There is also one vulnerability being actively exploited, CVE-2023-21674, highlighted in yellow below. This vulnerability could allow an attacker to gain SYSTEM privileges. The details of this exploit are not public but since it is currently being exploited then you can be sure more attacks are soon to come.
If your computer has a vulnerable processor and runs an unpatched operating system, it is not safe to work with sensitive information without the chance of leaking the information. This applies both to personal computers as well as cloud infrastructure. Luckily, there are software patches against Meltdown. 2b1af7f3a8
