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.
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-2023-44352 – Reflected Cross-Site Scripting (XSS)
- CVE-2023-44353 – Deserialization to RCE

CVE-2023-43177 – CrushFTP Remote Code Execution
CrushFTP Server is a multipurpose FTP server. The version prior to 10.5.1 is vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes leading to remote code execution.
POC – https://convergetp.com/2023/11/16/crushftp-zero-day-cve-2023-43177-discovered/
At least 15000 CrushFTP endpoints are exposed on Shodan.
CVE-2023-22516 – Bamboo Data Center and Server Remote Code Execution
This High severity RCE (Remote Code Execution) vulnerability was in Bamboo Data Center and Server. This RCE (Remote Code Execution) vulnerability allows an authenticated attacker to execute arbitrary code which has high impact to confidentiality, high impact to integrity, high impact to availability, and requires no user interaction.

CVE-2023-22521 – Crowd Data Center and Server Remote Code Execution
This High severity RCE (Remote Code Execution) vulnerability was introduced in version 3.4.6 of Crowd Data Center and Server. This RCE (Remote Code Execution) vulnerability allows an authenticated attacker to execute arbitrary code which has high impact to confidentiality, high impact to integrity, high impact to availability, and requires no user interaction.

OwnCloud Vulnerabilities
CVE-2023-49104: ownCloud oauth2 Subdomain redirect
This vulnerability affects ownCloud owncloud/oauth2 before 0.6.1, when Allow Subdomains is enabled. An attacker can exploit this vulnerability to redirect callbacks to a Top Level Domain controlled by the attacker. This could allow the attacker to steal the victim’s session cookies, or to execute arbitrary code on the victim’s machine.The vulnerability is caused by the fact that ownCloud does not properly validate the redirect-url parameter. This allows an attacker to pass in a crafted redirect-url that points to a domain that they control. When the victim clicks on a link that contains the malicious redirect-url, they will be redirected to the attacker’s domain.
CVE-2023-49105: ownCloud Unauthenticated File Access
This vulnerability affects ownCloud owncloud/core before 10.13.1. It allows an attacker to access, modify, or delete any file without authentication if they know the username of the victim and the victim has no signing-key configured. This is because the system accepts pre-signed URLs even when the file owner has not configured a signing key. The earliest affected version is 10.6.0.
A staggering 21k endpoints are exposed on Shodan.
CVE-2021-22150 – Kibana server Remote Code Execution
This vulnerability was discovered when a user with Fleet admin permissions could upload a malicious package. Due to using an older version of the js-yaml library, this package would be loaded in an insecure manner, allowing an attacker to execute commands on the Kibana server.

Important Weekly Threat Actors
CVE-2023-46604 – Kinsing malware operator
The Java OpenWire protocol marshaller is vulnerable to Remote Code Execution. This vulnerability may allow a remote attacker with network access to either a Java-based OpenWire broker or client to run arbitrary shell commands by manipulating serialized class types in the OpenWire protocol to cause either the client or the broker (respectively) to instantiate any class on the classpath. This vulnerability was found to be exploited by Kinsing malware operator, a malware family distributed by the H2Miner botnet, is known for targeting Linux-based infrastructure systems including Docker container hosts, Redis instances, and (in recent weeks) Salt servers.
The POC of the above vulnerability can be found here below:

About FireCompass:
FireCompass is a SaaS platform for Continuous Automated Pen Testing, Red Teaming and External Attack Surface Management (EASM). FireCompass continuously indexes and monitors the deep, dark and surface webs using nation-state grade reconnaissance techniques. The platform automatically discovers an organization’s digital attack surface and launches multi-stage safe attacks, mimicking a real attacker, to help identify breach and attack paths that are otherwise missed out by conventional tools.
