U.S. Government Disclosed 39 Zero-Day Vulnerabilities in 2023, Per First-Ever Report
In a first-of-its-kind report, the US government has revealed that it disclosed 39 zero-day software vulnerabilities to vendors or the public in 2023 for the purpose of getting the vulnerabilities patched or mitigated, as opposed to retaining them to use in hacking operations. It’s the first time the government has revealed specific numbers about its controversial Vulnerabilities Equities Process (VEP) — the process it uses to adjudicate decisions about whether zero-day vulnerabilities it discovers should be kept secret so law enforcement, intelligence agencies, and the military can exploit them in hacking operations or be disclosed to vendors to fix them. Zero-day vulnerabilities are security holes in software that are unknown to the software maker and are therefore unpatched at the time of discovery, making systems that use the software at risk of being hacked by anyone who discovers the flaw.
Active Exploitation of Zero-day Zyxel CPE Vulnerability (CVE-2024-40891)
After identifying a significant overlap between IPs exploiting CVE-2024-40891 and those classified as Mirai, the team investigated a recent variant of Mirai and confirmed that the ability to exploit CVE-2024-40891 has been incorporated into some Mirai strains. GreyNoise is observing active exploitation attempts targeting a zero-day critical command injection vulnerability in Zyxel CPE Series devices tracked as CVE-2024-40891. At this time, the vulnerability is not patched, nor has it been publicly disclosed. Attackers can leverage this vulnerability to execute arbitrary commands on affected devices, leading to complete system compromise, data exfiltration, or network infiltration. At publication, Censys is reporting over 1,500 vulnerable devices online.

2023 Top Routinely Exploited Vulnerabilities | CISA
In 2023, malicious cyber actors exploited more zero-day vulnerabilities to compromise enterprise networks compared to 2022, allowing them to conduct cyber operations against higher-priority targets. In 2023, the majority of the most frequently exploited vulnerabilities were initially exploited as a zero-day, which is an increase from 2022, when less than half of the top exploited vulnerabilities were exploited as a zero-day. Malicious cyber actors continue to have the most success exploiting vulnerabilities within two years after public disclosure of the vulnerability. The utility of these vulnerabilities declines over time as more systems are patched or replaced. Malicious cyber actors find less utility from zero-day exploits when international cybersecurity efforts reduce the lifespan of zero-day vulnerabilities.
Fortinet FortiManager CVE-2024-47575 Exploited in Zero-Day Attacks
On Wednesday, October 23, 2024, security company Fortinet published an advisory on CVE-2024-47575, a critical zero-day vulnerability affecting their FortiManager network management solution.

Beware the Unpatchable: Corona Mirai Botnet Spreads via Zero-Day
- The Akamai Security Intelligence and Response Team (SIRT) has observed a botnet campaign that is abusing several previously exploited vulnerabilities, as well as a zero-day vulnerability discovered by the SIRT. CVE-2024-7029 (discovered by Aline Eliovich) is a command injection vulnerability found in the brightness function of AVTECH closed-circuit television (CCTV) cameras that allows for remote code execution (RCE). Once injected, the botnet spreads a Mirai variant with string names that reference the COVID-19 virus that has been seen since at least 2020. * We have included a list of indicators of compromise (IOCs) to assist in defense against this threat.
