Microsoft Threat Intelligence has discovered a new macOS vulnerability, dubbed “HM Surf”, that allows attackers to bypass the operating system’s Transparency, Consent, and Control (TCC) technology and gain unauthorized access to protected user data. The vulnerability involves removing TCC protection for the Safari browser directory and modifying a configuration file to access user data, including browsing history, camera, microphone, and location, without user consent. Microsoft has reported the vulnerability to Apple, which has released a fix as part of a macOS security update. Users are urged to install the update as soon as possible to mitigate the risk. This vulnerability highlights the importance of keeping operating systems and applications updated to protect against emerging threats and the persistent challenges of maintaining robust security in complex software environments.
A critical vulnerability in Ivanti’s Cloud Service Appliance (CSA) has been actively exploited by attackers. The flaw, tracked as CVE-2024-8190, allows attackers to gain unauthorized access to sensitive data and execute arbitrary commands on vulnerable systems. The vulnerability exists in the CSA’s authentication mechanism and can be exploited by attackers who can send specially crafted requests to the CSA. This attack vector allows attackers to bypass the CSA’s security measures and gain access to the underlying operating system. The vulnerability has been exploited in the wild by a suspected nation-state adversary. There are strong indications that China is behind the attacks. Organizations using Ivanti CSA should prioritize patching the vulnerability immediately to reduce their risk of being compromised.
The US Cybersecurity and Infrastructure Security Agency (CISA) has added three new security vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, due to confirmed reports of active exploitation in the wild. These vulnerabilities pose significant risks to organizations and require immediate attention. The three vulnerabilities added to the KEV Catalog include a format string vulnerability in multiple Fortinet products, a SQL injection vulnerability in Ivanti Cloud Services Appliance (CSA), and an OS command injection vulnerability in Ivanti CSA. The addition of these vulnerabilities to the KEV Catalog highlights the ongoing threat posed by malicious cyber actors who actively exploit known vulnerabilities. CISA urges all organizations to prioritize timely remediation of vulnerabilities listed in the KEV Catalog as part of their vulnerability management practices to reduce their exposure to cyberattacks.
