On February 17, 2023, a URL parsing vulnerability in certain versions of the Python programming language was published with the ID CVE-2023-24329. The issue lies in the urllib.parse module which contains functions for breaking URLs into components and combining them back into full URLs. According to the description provided on NVD, the vulnerability has a CVSS v3 base score of 7.5 which indicates it is highly severe. If exploited, this flaw could enable attackers to bypass security protections and filters that rely on URL blocklisting. Essentially, by supplying specially crafted URLs, malicious actors may be able to bypass implemented domain or protocol blacklists. This creates serious security implications, as failure to filter dangerous URLs could lead to scenarios like arbitrary file reads, SSRF attacks, unauthorized access to internal networks, and remote code execution. Organizations…

The emergence of large language model (LLMs) applications like ChatGPT has sparked a revolution in artificial intelligence. These models can generate remarkably human-like text and code, unlocking new possibilities. However, the excitement over LLMs has caused their integration and adoption to rapidly outpace security considerations. As organizations implement LLMs into client offerings and business operations, they expose themselves to serious vulnerabilities. LLMs introduce new attack surfaces and risks compared to traditional software applications. Their core natural language processing capabilities can be exploited in ways developers are unaccustomed to. Attackers are already developing methods to manipulate LLMs through crafted inputs. Without proper safeguards, LLMs risk leaking sensitive data, enabling social engineering, and threatening backend infrastructure. To address these concerns, OWASP recently released its OWASP Top 10 for Large Language Model Applications report. OWASP is an international…

Some of our readers have requested information about Docker and container technology. We have decided to publish an article on Docker Containers to help many users understand the technical aspects of Docker and containers. In this blog post, we will clarify the concept of containers and their different types, explain what Docker is, explore the relationship between Docker and containers, discuss the appropriate use cases for Docker, delve into the problems Docker solves in development, address whether Docker replaces virtualization, explain the differences between Docker containers and virtual machines, and answer a few more questions that will aid in understanding Docker. Before we delve directly into Docker, let’s begin by exploring containers, as it will make it easier to comprehend Docker if you are familiar with containers. What is a Container? A…

The advancement of artificial intelligence (AI) has brought numerous benefits to various industries and individuals. However, the dark side of AI is now emerging, as cybercriminals have started to harness the power of generative AI tools for their malicious activities. SlashNext, an email security provider has recently uncovered a malicious GPT tool sold as WormGPT in the sig market. WormGPT is a blackhat alternative to GPT models, based on the open-source large-scale language model GPT-J. This tool offers chat memory retention, and code formatting capabilities, and supports unlimited characters, making it particularly dangerous for businesses and individuals alike. Its primary use is for phishing and business email compromise (BEC) attacks, adding a new level of sophistication to these ever-evolving cyber threats. As AI technology continues to advance, the battle between AI-powered defenses and…

Security researcher, Maddie Stone from Google Threat Analysis Group (TAG) uncover a new vulnerability in Zimbra Collaboration Suite. This is a critical (Cross Site Scripting) XSS vulnerability that could potentially impact the confidentiality and integrity of your data, it is important to Patch the Vulnerability at the earliest. We have created this post to let you know how to fix the Critical XSS Vulnerability in Zimbra Collaboration Suite. A Short Note About the XSS Vulnerability In short, Cross-Site Scripting (XSS) is a common security vulnerability typically found in web applications. This vulnerability allows attackers to inject malicious scripts into web pages viewed by other users. It occurs when an application includes untrusted data in a new web page without proper validation or escaping. XSS attacks can lead to a range of problems…

Citrix published a Security Bulletin on 19th July 2023 in which it disclosed 3 new vulnerabilities in Citrix ADC and Gateway Products. All three tracked under the identifiers CVE-2023-3519, CVE-2023-3466, and CVE-2023-3467 are rated Critical and High in severity with CVSS scores of 9.8, 8.3, and 8 respectively. The exploitation of these vulnerabilities would allow adversaries to perform Code Injection, Remote Code Execution, Privilege Escalation to root, and Reflected Cross-Site Scripting attacks on vulnerable versions of NetScaler ADC (formerly Citrix ADC) and NetScaler Gateway (formerly Citrix Gateway. It is highly recommended that organizations who use NetSclar/Citrix ADC and Gateway Products should patch all these vulnerabilities in Citrix ADC and Gateway Products. Without further due, let’s see how to fix CVE-2023-3519 (Unauthenticated Remote Code Execution Vulnerability in Citrix Products) with the other two vulnerabilities in this post.…
