Microsoft has shared technical details about a now-fixed, actively exploited critical security vulnerability affecting SolarWinds Serv-U managed file transfer service that it has attributed with "high confidence" to a threat actor operating out of China. In mid-July, the Texas-based company  remedied  a remote code execution flaw ( CVE-2021-35211 ) that was rooted in Serv-U's implementation of the Secure Shell (SSH) protocol, which could be abused by attackers to run arbitrary code on the infected system, including the ability to install malicious programs and view, change, or delete sensitive data. "The Serv-U SSH server is subject to a pre-auth remote code execution vulnerability that can be easily and reliably exploited in the default configuration," Microsoft Offensive Research and Security Engineering team said in a  detailed write-up  describing the exploit. "An attacker can exploit this vulnerability by connecting to the open SSH port and sendin

A German security researcher has publicly disclosed details of a serious vulnerability in one of the most popular FTP server applications, which is currently being used by more than one million servers worldwide. The vulnerable software in question is ProFTPD , an open source FTP server used by a large number of popular businesses and websites including SourceForge, Samba and Slackware, and comes pre-installed with many Linux and Unix distributions, like Debian. Discovered by Tobias Mädel , the vulnerability resides in the mod_copy module of the ProFTPD application, a component that allows users to copy files/directories from one place to another on a server without having to transfer the data to the client and back. According to Mädel, an incorrect access control issue in the mod_copy module could be exploited by an authenticated user to unauthorizedly copy any file on a specific location of the vulnerable FTP server where the user is otherwise not allowed to write a file.

The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

This newly discovered bugs in Java and Python is a big deal today. The two popular programming languages, Java and Python, contain similar security flaws that can be exploited to send unauthorized emails and bypass any firewall defenses. And since both the flaws remain unpatched, hackers can take advantage to design potential cyber attack operations against critical networks and infrastructures. The unpatched flaws actually reside in the way Java and Python programming languages handle File Transfer Protocol (FTP) links, where they don't syntax-check the username parameter, which leads to, what researchers call, protocol injection flaw. Java/Python FTP Injection to Send Unauthorized SMTP Emails In a blog pos t published over the past week, security researcher Alexander Klink detailed the FTP protocol injection vulnerability in Java's XML eXternal Entity (XXE) that allows attackers to inject non-FTP malicious commands inside an FTP connection request. To demonst

The open-source Wget application which is most widely used on Linux and Unix systems for retrieving files from the web has found vulnerable to a critical flaw. GNU Wget is a command-line utility designed to retrieve files from the Web using HTTP, HTTPS, and FTP, the most widely used Internet protocols. Wget can be easily installed on any Unix-like system and has been ported to many environments, including Microsoft Windows, Mac OS X, OpenVMS, MorphOS and AmigaOS. When a recursive directory fetch over FTP server as the target, it would let an attacker " create arbitrary files, directories or symbolic links " due to a symlink flaw. IMPACT OF SYMLINK ATTACK " It was found that wget was susceptible to a symlink attack which could create arbitrary files, directories or symbolic links and set their permissions when retrieving a directory recursively through FTP ," developer Vasyl Kaigorodov wrote in a Red Hat Bugzilla comment . A remote unauthentica

DuckDuckGo , a private search engine that doesn't track your data over the internet and respects your online privacy ,  offers hundreds of Goodies that let you quickly do certain things like Programming, Math, Geek, Music related things. In our previous article, we have posted Cryptography hacks using DuckDuckGo search engine and today we are going to give another tutorial on DuckDuckGo Goodies for Sysadmins . Meaning of FTP Code: Being a system administrator, you might need to connect to a number of FTP servers. While handling FTP service you must be aware of the response code that it will give you when you initiate a connection or a new command. The FTP server response code will be of three digits and each digit has a special meaning. First digit denotes whether the response is good, bad or incomplete. There are hundreds of such FTP response codes. DuckDuckGo provides system administrators a facility to find the meaning of the response code received from the FTP

Malware code can be very small, and the impact can be very severe! The Antivirus firm AVAST spotted a malicious version of the open source FTP (File Transfer Protocol) software ' FileZilla ' out in the wild. The software is open source, but has been modified by the hackers that steal users' credentials, offered on various hacked sites for download with banner or text ads. Once installed, the software's appearance and functionalities are equal to the original version, so a user cannot distinguish between the fake or real one, and the malware version of the " .exe " file is just slightly smaller than the real one. " The installed malware FTP client looks like the official version and it is fully functional! You can't find any suspicious behavior, entries in the system registry, communication or changes in application GUI ." The only difference is that the malware version use 2.46.3-Unicode and the official installer use v2.45-Unicode , as

File transfer services such as FTP or HTTP has been the most common way of file transfer for business requirements. Typically what a file transfer means is that a file transfer protocol such as FTP or HTTP is used to send the stream of bits stored as a single unit in a file system including file name, file size, timestamp and other metadata from one host to another host over a TCP-based network such as the Internet. But this process is not foolproof. FTP, by itself, is not a secure file transfer protocol and it has a lot of security vulnerabilities. It's a known fact that FTP doesn't provide any encryption for data transfer. Most of the times, the requirement in any business is pretty simple: to transfer files between two endpoints in different locations, and the parties involved do not think much about how secure the file transfer process is going to be. Using FTP for official file transfer can leave your data transmission exposed to many security attacks: FTP Bounce Attack Gener
