CISA says a maximum severity vulnerability in AMI's MegaRAC Baseboard Management Controller (BMC) software, which enables attackers to hijack and brick servers, is currently under active exploitation.
CISA has confirmed that a maximum severity vulnerability in AMI's MegaRAC Baseboard Management Controller (BMC) software is now actively exploited in attacks.
The MegaRAC BMC firmware provides remote system management capabilities for troubleshooting servers without being physically present, and it's used by several vendors (including HPE, Asus, and ASRock) that supply equipment to cloud service providers and data centers.
This authentication bypass security flaw (tracked as CVE-2024-54085) can be exploited by remote unauthenticated attackers in low-complexity attacks that don't require user interaction to hijack and potentially brick unpatched servers.
An APT hacking group known as 'Stealth Falcon' exploited a Windows WebDav RCE vulnerability in zero-day attacks since March 2025 against defense and government organizations in Turkey, Qatar, Egypt, and Yemen.
Stealth Falcon (aka 'FruityArmor') is an advanced persistent threat (APT) group known for conducting cyberespionage attacks against Middle East organizations.
The flaw, tracked under CVE-2025-33053, is a remote code execution (RCE) vulnerability that arises from the improper handling of the working directory by certain legitimate system executables.
Specifically, when a .url file sets its WorkingDirectory to a remote WebDAV path, a built-in Windows tool can be tricked into executing a malicious executable from that remote location instead of the legitimate one.
This allows attackers to force devices to execute arbitrary code remotely from WebDAV servers under their control without dropping malicious files locally, making their operations stealthy and evasive.
The vulnerability was discovered by Check Point Research, with Microsoft fixing the flaw in the latest Patch Tuesday update, released yesterday.
Hackers are actively exploiting CVE-2025-49113, a critical vulnerability in the widely used Roundcube open-source webmail application that allows remote execution.
The security issue has been present in Roundcube for over a decade and impacts versions of Roundcube webmail 1.1.0 through 1.6.10. It received a patch on June 1st.
It took attackers just a couple of days to reverse engineer the fix, weaponize the vulnerability, and start selling a working exploit on at least one hacker forum.
Roundcube is one of the most popular webmail solutions as the product is included in offers from well-known hosting providers such as GoDaddy, Hostinger, Dreamhost, or OVH.
"Email armageddon"
CVE-2025-49113 is a post-authentication remote code execution (RCE) vulnerability that received a critical severity score of 9.9 out of 10 and is described as “email armageddon.”
It was discovered and reported by Kirill Firsov, the CEO of the cybersecurity company FearsOff, who decided to publish the technical details before the end of the responsible disclosure period because an exploit had become available.
