CVE-2023-20155: Cisco Security Advisory: Cisco Firepower Management Center Software Log API Denial of Service Vulnerability

A vulnerability in a logging API in Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to cause the device to become unresponsive or trigger an unexpected reload. This vulnerability could also allow an attacker with valid user credentials, but not Administrator privileges, to view a system log file that they would not normally have access to. This vulnerability is due to a lack of rate-limiting of requests that are sent to a specific API that is related to an FMC log. An attacker could exploit this vulnerability by sending a high rate of HTTP requests to the API. A successful exploit could allow the attacker to cause a denial of service (DoS) condition due to the FMC CPU spiking to 100 percent utilization or to the device reloading. CPU utilization would return to normal if the attack traffic was stopped before an unexpected reload was triggered.

CVE-2023-20244: Cisco Security Advisory: Cisco Firepower Threat Defense Software for Cisco Firepower 2100 Series Firewalls Inspection Rules Denial of Service Vulnerability

A vulnerability in the internal packet processing of Cisco Firepower Threat Defense (FTD) Software for Cisco Firepower 2100 Series Firewalls could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of certain packets when they are sent to the inspection engine. An attacker could exploit this vulnerability by sending a series of crafted packets to an affected device. A successful exploit could allow the attacker to deplete all 9,472 byte blocks on the device, resulting in traffic loss across the device or an unexpected reload of the device. If the device does not reload on its own, a manual reload of the device would be required to recover from this state.

CVE-2023-20114: Cisco Security Advisory: Cisco Firepower Management Center Software Arbitrary File Download Vulnerability

A vulnerability in the file download feature of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to download arbitrary files from an affected system. This vulnerability is due to a lack of input sanitation. An attacker could exploit this vulnerability by sending a crafted HTTPS request. A successful exploit could allow the attacker to download arbitrary files from the affected system.

CVE-2023-20086: Cisco Security Advisory: Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software ICMPv6 Message Processing Denial of Service Vulnerability

A vulnerability in ICMPv6 processing of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. This vulnerability is due to improper processing of ICMPv6 messages. An attacker could exploit this vulnerability by sending crafted ICMPv6 messages to a targeted Cisco ASA or FTD system with IPv6 enabled. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.

CVE-2023-4198: (CVE-2023-4198) Dolibarr ERP CRM (

Improper Access Control in Dolibarr ERP CRM <= v17.0.3 allows an unauthorized authenticated user to read a database table containing customer data

CVE-2023-5360

The Royal Elementor Addons and Templates WordPress plugin before 1.3.79 does not properly validate uploaded files, which could allow unauthenticated users to upload arbitrary files, such as PHP and achieve RCE.

CVE-2023-5116: Live updates from Excel <= 2.3.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode — Wordfence Intelligence

The Live updates from Excel plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'ipushpull_page' shortcode in versions up to, and including, 2.3.2 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Ubuntu Security Notice USN-6460-1

Ubuntu Security Notice 6460-1 - It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service. It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux kernel did not properly perform data buffer size validation in some situations. A physically proximate attacker could use this to craft a malicious USB device that when inserted, could cause a denial of service or possibly expose sensitive information.

Ubuntu Security Notice USN-6454-2

Ubuntu Security Notice 6454-2 - Kyle Zeng discovered that the netfilter subsystem in the Linux kernel contained a race condition in IP set operations in certain situations. A local attacker could use this to cause a denial of service. Alex Birnberg discovered that the netfilter subsystem in the Linux kernel did not properly validate register length, leading to an out-of- bounds write vulnerability. A local attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice USN-6441-3

Ubuntu Security Notice 6441-3 - Ross Lagerwall discovered that the Xen netback backend driver in the Linux kernel did not properly handle certain unusual packets from a paravirtualized network frontend, leading to a buffer overflow. An attacker in a guest VM could use this to cause a denial of service or possibly execute arbitrary code. Kyle Zeng discovered that the networking stack implementation in the Linux kernel did not properly validate skb object size in certain conditions. An attacker could use this cause a denial of service or possibly execute arbitrary code.
