Zero-Day Alert: Three Critical Ivanti CSA Vulnerabilities Actively Exploited

Oct 08, 2024 Zero-Day / Vulnerability
Ivanti has warned that three new security vulnerabilities impacting its Cloud Service Appliance (CSA) have come under active exploitation in the wild. The zero-day flaws are being weaponized in conjunction with another flaw in CSA that the company patched last month, the Utah-based software services provider said. Successful exploitation of these vulnerabilities could allow an authenticated attacker with admin privileges to bypass restrictions, run arbitrary SQL statements, or obtain remote code execution. "We are aware of a limited number of customers running CSA 4.6 patch 518 and prior who have been exploited when CVE-2024-9379, CVE-2024-9380, or CVE-2024-9381 are chained with CVE-2024-8963," the company said . There is no evidence of exploitation against customer environments running CSA 5.0. A brief description of the three shortcomings is as follows - CVE-2024-9379 (CVSS score: 6.5) - SQL injection in the admin web console of Ivanti CSA before version 5.0.2 all
How to Get Going with CTEM When You Don't Know Where to Start

How to Get Going with CTEM When You Don't Know Where to Start

Oct 04, 2024Vulnerability Management / Security Posture
Continuous Threat Exposure Management (CTEM) is a strategic framework that helps organizations continuously assess and manage cyber risk. It breaks down the complex task of managing security threats into five distinct stages: Scoping, Discovery, Prioritization, Validation, and Mobilization. Each of these stages plays a crucial role in identifying, addressing, and mitigating vulnerabilities - before they can be exploited by attackers.  On paper, CTEM sounds great . But where the rubber meets the road – especially for CTEM neophytes - implementing CTEM can seem overwhelming. The process of putting CTEM principles into practice can look prohibitively complex at first. However, with the right tools and a clear understanding of each stage, CTEM can be an effective method for strengthening your organization's security posture.  That's why I've put together a step-by-step guide on which tools to use for which stage. Want to learn more? Read on… Stage 1: Scoping  When you're defin

North Korean Hackers Deploy FudModule Rootkit via Chrome Zero-Day Exploit

North Korean Hackers Deploy FudModule Rootkit via Chrome Zero-Day Exploit

Aug 31, 2024 Rootkit / Threat Intelligence
A recently patched security flaw in Google Chrome and other Chromium web browsers was exploited as a zero-day by North Korean actors in a campaign designed to deliver the FudModule rootkit. The development is indicative of the persistent efforts made by the nation-state adversary, which has made a habit of incorporating rafts of Windows zero-day exploits into its arsenal in recent months. Microsoft, which detected the activity on August 19, 2024, attributed it to a threat actor it tracks as Citrine Sleet (formerly DEV-0139 and DEV-1222), which is also known as AppleJeus, Labyrinth Chollima, Nickel Academy, and UNC4736 . It's assessed to be a sub-cluster within the Lazarus Group (aka Diamond Sleet and Hidden Cobra). It's worth mentioning that the use of the AppleJeus malware has also been previously attributed by Kaspersky to another Lazarus subgroup called BlueNoroff (aka APT38, Nickel Gladstone, and Stardust Chollima), indicative of the infrastructure and toolset sharin

APT-C-60 Group Exploit WPS Office Flaw to Deploy SpyGlace Backdoor

Aug 28, 2024 Cyber Attack / Vulnerability
A South Korea-aligned cyber espionage has been linked to the zero-day exploitation of a now-patched critical remote code execution flaw in Kingsoft WPS Office to deploy a bespoke backdoor dubbed SpyGlace. The activity has been attributed to a threat actor dubbed APT-C-60 , according to cybersecurity firms ESET and DBAPPSecurity. The attacks have been found to infect Chinese and East Asian users with malware. The security flaw in question is CVE-2024-7262 (CVSS score: 9.3), which stems from a lack of proper validation of user-provided file paths. This loophole essentially allows an adversary to upload an arbitrary Windows library and achieve remote code execution. The bug "allows code execution via hijacking the control flow of the WPS Office plugin component promecefpluginhost.exe," ESET said , adding it found another way to achieve the same effect. The second vulnerability is tracked as CVE-2024-7263 (CVSS score: 9.3). The attack conceived by APT-C-60 weaponizes the
