Detailed Analysis :
Top Vulnerabilities Being Exploited in November
CVE-2023-46604 – Apache ActiveMQ
Apache ActiveMQ is vulnerable to Remote Code Execution.The vulnerability may allow a remote attacker with network access to a broker to run arbitrary shell commands by manipulating serialized class types in the OpenWire protocol to cause the broker to instantiate any class on the classpath. Users are recommended to upgrade to version 5.15.16, 5.16.7, 5.17.6, or 5.18.3, which fixes this issue.
Here are the industries and companies that are affected by this CVE.

Most impacted countries are USA and China while Amazon Services are getting affected the most.
CVE-2023-22518 – Atlassian Confluence Data Center Improper Authorization
Atlassian Confluence Data Center and Server has improper authorization which allows an unauthenticated attacker to reset Confluence and create a Confluence instance administrator account. Using this account, an attacker can then perform all administrative actions that are available to Confluence instance administrators leading to – but not limited to – full loss of confidentiality, integrity and availability. This CVE has been listed in CISA exploited in the wild list for this week.
CVE-2023-48029 – CoreBos CSV Injection
CoreBos is an open-source and free business application framework that helps small and medium businesses to handle all the day to day tasks. Corebos 8.0 and below is vulnerable to CSV Injection. An attacker with low privileges can inject a malicious command into a table. This vulnerability is exploited when an administrator visits the user management section, exports the data to a CSV file, and then opens it, leading to the execution of the malicious payload on the administrator’s computer.
Shodan shows 2879 endpoints and the USA has the most number of them.
CVE-2023-26205 – FortiADC Automation Privilege Escalation
FortiADC Automation version 7.1.0 through 7.1.2, 7.0 all versions, 6.2 all versions, 6.1 all versions may allow an authenticated low-privileged attacker to escalate their privileges to super_admin via a specific crafted configuration of fabric automation CLI script.
Shodan shows 2879 endpoints and the USA has the most number of them.
CVE-2023-34991 – Fortinet FortiWLM SQL Command Injection
A improper neutralization of special elements used in an sql command (‘sql injection’) in Fortinet FortiWLM version 8.6.0 through 8.6.5 and 8.5.0 through 8.5.4 and 8.4.0 through 8.4.2 and 8.3.0 through 8.3.2 and 8.2.2 allows attacker to execute unauthorized code or commands via a crafted http request.
Microsoft Exchange Server Vulnerabilities
This on 14th November, 2023 – Tuesday was the Microsoft Patch Tuesday where they disclosed several numbers of vulnerabilities. One of them being the popular Microsoft Exchange Server which is a prime target for threat actors. Four vulnerabilities were released, here is the list.- CVE-2023-36035 – Microsoft Exchange Server Spoofing Vulnerability

- CVE-2023-36050 – Microsoft Exchange Server Spoofing Vulnerability
- CVE-2023-36439 – Microsoft Exchange Server Remote Code Execution
Adobe Coldfusion Vulnerabilities
Adobe Coldfusion is a popular web application development tool which had a fair share of vulnerabilities this year along with various threat actors abusing it. This week it released five CVEs in version 2023.5
- CVE-2023-26347 – Improper Access Control vulnerability
- CVE-2023-44350 – Deserialization to RCE
- CVE-2023-44351 – Deserialization to RCE

- CVE-2023-44353 – Deserialization to RCE
Detailed Analysis: Top Malwares And Threat Actors Of November
CVE-2023-46604 – TellYouThePass ransomware
Apache ActiveMQ is vulnerable to Remote Code Execution. The vulnerability may allow a remote attacker with network access to a broker to run arbitrary shell commands by manipulating serialized class types in the OpenWire protocol to cause the broker to instantiate any class on the classpath. This vulnerability was found to be exploited by a ransomware group named, TellYouThePass ransomware.

CVE-2019-0708 – Kimsuky
A remote code execution vulnerability exists in Remote Desktop Services formerly known as Terminal Services when an unauthenticated attacker connects to the target system using RDP and sends specially crafted requests, aka ‘Remote Desktop Services Remote Code Execution Vulnerability’. This vulnerability was found to be exploited by a North Korean state backed hacker group named, Kimsuky.
The POC of the above vulnerability can be found here: https://packetstormsecurity.com/files/162960/Microsoft-RDP-Remote-Code-Execution.html
CVE-2023-4966 – LockBit Ransomware Gang
Sensitive Information Disclosure in NetScaler ADC and NetScaler Gateway when configured as a Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) or AAA virtual server. This vulnerability is found to be exploited by the LockBit ransomware gang.
POC of the above vulnerabilty:
https://github.com/mlynchcogent/CVE-2023-4966-POC
CVE-2023-40044 and CVE-2023-42657 – Dark Pink APT
In WS_FTP Server versions prior to 8.7.4 and 8.8.2, a pre-authenticated attacker could leverage a .NET deserialization vulnerability in the Ad Hoc Transfer module to execute remote commands on the underlying WS_FTP Server operating system and
a directory traversal vulnerability was discovered. An attacker could leverage this vulnerability to perform file operations on files and folders outside of their authorized WS_FTP folder path. Attackers could also escape the context of the WS_FTP Server file structure and perform the same level of operations (delete, rename, rmdir, mkdir) on file and folder locations on the underlying operating system. These vulnerabilities are found to be exploited by Dark Pink APT group.
