SSH shaken, not stirred by Terrapin vulnerability
2023-12-20 08:34

This isn't one to panic over, because someone will need to man-in-the-middle your vulnerable connection rather than directly attack your server; it's a downgrade attack primarily rather than a decryption or command injection issue; and there are ways to immediate protect yourself from Terrapin attacks. There are three issues to be aware of: CVE-2023-48795, which is the generic exploitable protocol-level SSH vulnerability; and CVE-2023-46445 and CVE-2023-46446 specific to the Python SSH client AsyncSSH, which has an estimated 60,000 daily downloads.

Creating a formula for effective vulnerability prioritization
2023-12-18 05:00

Gorelik discusses challenges posed by regulatory frameworks, incomplete asset inventories, and manual methods, while also exploring the role of automated systems, the future of vulnerability prioritization in the face of evolving cyber threats, and key factors organizations should consider in building effective remediation strategies. A vulnerability with proven exploitability or a high probability of exploitation existing within an active internet-facing business application is likely a higher priority than a vulnerability residing within an unused application in a well-protected environment.

QNAP VioStor NVR vulnerability actively exploited by malware botnet
2023-12-16 16:17

A Mirai-based botnet named 'InfectedSlurs' is exploiting a remote code execution vulnerability in QNAP VioStor NVR devices to hijack and make them part of its DDoS swarm. The second zero-day vulnerability in the botnet's attacks is CVE-2023-47565, a high-severity OS command injection impacting QNAP VioStor NVR models running QVR firmware 4.x. QNAP published an advisory on December 7, 2023, explaining that the previously unknown issue was fixed in QVR firmware 5.x and later, which is available to all actively supported models.

Attackers are trying to exploit Apache Struts vulnerability (CVE-2023-50164)

2023-12-13 11:03

Over a year has passed since Sophos delivered patches for a vulnerability affecting Sophos Firewalls that was being actively exploited by attackers, and now they have pushed additional ones to protect vulnerable EOL devices. "In December 2023, we delivered an updated fix after identifying new exploit attempts against this same vulnerability in older, unsupported versions of the Sophos Firewall," the company shared on Monday by updating of the original security advisory.

Lazarus exploit Log4Shell vulnerability to deliver novel RAT malware
2023-12-12 14:33

North Korea-backed group Lazarus has been spotted exploiting the Log4Shell vulnerability and novel malware written in DLang. "This campaign consists of continued opportunistic targeting of enterprises globally that publicly host and expose their vulnerable infrastructure to n-day vulnerability exploitation such as CVE-2021-44228. We have observed Lazarus target manufacturing, agricultural and physical security companies," Cisco Talos researchers shared.
