Researchers from Bitsight and Curesec have jointly discovered a high-severity vulnerability — tracked as CVE-2023-29552 — in the Service Location Protocol (SLP), a legacy Internet protocol. Attackers exploiting this vulnerability could leverage vulnerable instances to launch massive Denial-of-Service (DoS) amplification attacks with a factor as high as 2200 times, potentially making it one of the largest amplification attacks ever reported.

Today, security and development teams are drowning in vulnerabilities. Most security tools identify issues, but don’t provide reliable prioritization or simplify remediation. To help solve these challenges, Sysdig runtime vulnerability management – part of Sysdig’s Cloud Native Application Protection Platform (CNAPP) – provides a runtime image scanner coupled with an eBPF probe to analyze container behavior and identify the vulnerable packages that are in use at runtime.

Java is a powerful backend programming language that can also be used to write HTML pages for web applications. However, developers must know the potential security risks associated with Cross-Site Scripting (XSS) attacks when creating these pages. With the rise of modern templating frameworks, preventing security attacks through proper input validation and encoding techniques has become easier.

Earlier today, April 25, 2023, researchers Pedro Umbelino at Bitsight and Marco Lux at Curesec published their discovery of CVE-2023-29552, a new DDoS reflection/amplification attack vector leveraging the SLP protocol. If you are a Cloudflare customer, your services are already protected from this new attack vector.

By default, the WordPress administrative login page displays a helpful error message whenever an account user types in the wrong username/email address or password. Unfortunately, these same helpful error messages can also be abused to assist a threat actor to validate account usernames/email addresses and/or passwords. An incorrect username/password guess combination generates the following error message: “The username ‘name-entered’ is not registered on this site”.

After COVID, enterprise IT security got turned on its head. As the world adjusted to working from home, and continues to, IT teams worked overtime to enable remote access for millions of employees. This transition has gone smoothly for most organizations, but many security gaps still remain years later. The SolarWinds data breach is a worrying example. It shows how vulnerable organizations are to malicious activity in our changing risk environment.

Since the inception of the internet and the World Wide Web (WWW), HTML has been a fundamental part of digital communication, enabling document exchange services between various devices on the network. Developed by Tim Berners-Lee, the father of the WWW, in 1993, the markup language is still used to display documents on web browsers today.

On Thursday, April 20, 2023, VMware disclosed a critical deserialization vulnerability (CVE-2023-20864) in VMware Aria Operations for Logs—formerly known as vRealize Log Insight—that could result in unauthenticated remote code execution (RCE) as root. The vulnerability was responsibly disclosed to VMware through the Zero Day Initiative and has not been actively exploited in campaigns. Furthermore, we have not identified a public proof of concept (PoC) exploit for CVE-2023-20864.
