Cybersecurity researchers have disclosed details of a high-severity flaw impacting the popular async-tar Rust library and its forks, including tokio-tar, that could result in remote code execution under certain conditions. The vulnerability, tracked as CVE-2025-62518 (CVSS score: 8.1), has been codenamed TARmageddon by Edera, which discovered the issue in late August 2025. It impacts several widely-used projects, such as testcontainers and wasmCloud. "In the worst-case scenario, this vulnerability has a severity of 8.1 (High) and can lead to Remote Code Execution (RCE) through file overwriting attacks, such as replacing configuration files or hijacking build backends," the Seattle-based security company said . The problem is compounded by the fact that tokio-tar is essentially abandonware despite attracting thousands of downloads via crates.io. Tokio-tar is a Rust library for asynchronously reading and writing TAR archives built atop the Tokio runtime for the programmi...

Anonymous Release Press Release for Operation Tarmageddon Early in July, Anonymous said it planned to attack oil firms and banks supporting the controversial extraction of oil from sand in Alberta, Canada. Exxon Mobil, ConocoPhillips, Canadian Oil Sands, Imperial Oil, and the Royal Bank of Scotland have been put on notice that they are likely to be targeted in Anonymous' latest operation, dubbed Project Tarmageddon.

In another finding that could expose developers to increased risk of a supply chain attack, it has emerged that nearly one-third of the packages in PyPI, the Python Package Index, trigger automatic code execution upon downloading them. "A worrying feature in pip/PyPI allows code to automatically run when developers are merely downloading a package," Checkmarx researcher Yehuda Gelb  said  in a technical report published this week. "Also, this feature is alarming due to the fact that a great deal of the malicious packages we are finding in the wild use this feature of code execution upon installation to achieve higher infection rates." One of the ways by which packages can be installed for Python is by executing the " pip install " command, which, in turn, invokes a file called "setup.py" that comes bundled along with the module. "setup.py," as the name implies, is a  setup script  that's used to specify metadata associated wit...

Email protection and network security services provider Barracuda is warning users about a zero-day flaw that it said has been exploited to breach the company's Email Security Gateway (ESG) appliances. The zero-day is being tracked as  CVE-2023-2868  and has been described as a remote code injection vulnerability affecting versions 5.1.3.001 through 9.2.0.006. The California-headquartered firm  said  the issue is rooted in a component that screens the attachments of incoming emails. "The vulnerability arises out of a failure to comprehensively sanitize the processing of .tar file (tape archives)," according to an  advisory  from the NIST's national vulnerability database. "The vulnerability stems from incomplete input validation of a user-supplied .tar file as it pertains to the names of the files contained within the archive. As a consequence, a remote attacker can specifically format these file names in a particular manner that will result in remote...

Pulse Secure has shipped a fix for a critical post-authentication remote code execution (RCE) vulnerability in its Connect Secure virtual private network (VPN) appliances to address an incomplete patch for an actively exploited flaw it previously resolved in October 2020. "The Pulse Connect Secure appliance suffers from an uncontrolled archive extraction vulnerability which allows an attacker to overwrite arbitrary files, resulting in Remote Code Execution as root," NCC Group's Richard Warren  disclosed  on Friday. "This vulnerability is a bypass of the patch for  CVE-2020-8260 ." "An attacker with such access will be able to circumvent any restrictions enforced via the web application, as well as remount the filesystem, allowing them to create a persistent backdoor, extract and decrypt credentials, compromise VPN clients, or pivot into the internal network," Warren added. The disclosure comes days after Ivanti, the company behind Pulse Secure,  p...

A severe remote code execution vulnerability in Zimbra's enterprise collaboration software and email platform is being actively exploited, with no patch currently available to remediate the issue. The shortcoming, assigned  CVE-2022-41352 , carries a critical-severity rating of CVSS 9.8, providing a pathway for attackers to upload arbitrary files and carry out malicious actions on affected installations. "The vulnerability is due to the method ( cpio ) in which Zimbra's antivirus engine ( Amavis ) scans inbound emails," cybersecurity firm Rapid7  said  in an analysis published this week. The issue is said to have been abused since early September 2022, according to  details  shared on Zimbra forums. While a fix is yet to be released, the software services company is urging users to install the "pax" utility and restart the Zimbra services. "If the  pax package  is not installed, Amavis will fall-back to using cpio, unfortunately the fall-back is ...

A new cyber attack campaign has been observed using spurious  MSIX  Windows app package files for popular software such as Google Chrome, Microsoft Edge, Brave, Grammarly, and Cisco Webex to distribute a novel malware loader dubbed  GHOSTPULSE . "MSIX is a Windows app package format that developers can leverage to package, distribute, and install their applications to Windows users," Elastic Security Labs researcher Joe Desimone  said  in a technical report published last week. "However, MSIX requires access to purchased or stolen code signing certificates making them viable to groups of above-average resources." Based on the installers used as lures, it's suspected that potential targets are  enticed  into downloading the MSIX packages through known techniques such as compromised websites, search engine optimization (SEO) poisoning, or malvertising. Launching the MSIX file opens a Windows prompting the users to click the Install button, doing so...

As many as 350,000 open source projects are believed to be potentially vulnerable to exploitation as a result of a security flaw in a Python module that has remained unpatched for 15 years. The open source repositories span a number of industry verticals, such as software development, artificial intelligence/machine learning, web development, media, security, and IT management. The shortcoming, tracked as  CVE-2007-4559  (CVSS score: 6.8), is rooted in the tarfile module, successful exploitation of which could lead to code execution from an arbitrary file write. "The vulnerability is a path traversal attack in the extract and extractall functions in the tarfile module that allow an attacker to overwrite arbitrary files by adding the '..' sequence to filenames in a TAR archive," Trellix security researcher Kasimir Schulz  said  in a writeup. Originally disclosed in August 2007, the bug has to do with how a specially crafted tar archive can be leveraged to overwr...

Researchers from China's Pangu Lab have disclosed details of a "top-tier" backdoor put to use by the Equation Group , an advanced persistent threat (APT) with alleged ties to the cyber-warfare intelligence-gathering unit of the U.S. National Security Agency (NSA). Dubbed " Bvp47 " owing to numerous references to the string "Bvp" and the numerical value "0x47" used in the encryption algorithm, the backdoor was extracted from Linux systems "during an in-depth forensic investigation of a host in a key domestic department" in 2013. The defense research group codenamed the attacks involving the deployment of Bvp47 "Operation Telescreen," with the implant featuring an "advanced covert channel behavior based on TCP SYN packets, code obfuscation, system hiding, and self-destruction design." Bvp47 is said to have been used on more than 287 targets in the academia, economic development, military, science, and telecom s...

A China-affiliated threat actor known as UNC6384 has been linked to a fresh set of attacks exploiting an unpatched Windows shortcut vulnerability to target European diplomatic and government entities between September and October 2025. The activity targeted diplomatic organizations in Hungary, Belgium, Italy, and the Netherlands, as well as government agencies in Serbia, Arctic Wolf said in a technical report published Thursday. "The attack chain begins with spear-phishing emails containing an embedded URL that is the first of several stages that lead to the delivery of malicious LNK files themed around European Commission meetings, NATO-related workshops, and multilateral diplomatic coordination events," the cybersecurity company said. The files are designed to exploit ZDI-CAN-25373 to trigger a multi-stage attack chain that culminates in the deployment of the PlugX malware using DLL side-loading. PlugX is a remote access trojan that's also referred to as Destroy...

Zimbra has  released patches  to contain an actively exploited security flaw in its enterprise collaboration suite that could be leveraged to upload arbitrary files to vulnerable instances. Tracked as  CVE-2022-41352  (CVSS score: 9.8), the issue affects a component of the Zimbra suite called  Amavis , an open source content filter, and more specifically, the cpio utility it uses to scan and extract archives. The flaw, in turn, is said to be rooted in another underlying vulnerability ( CVE-2015-1197 ) that was first disclosed in early 2015, which  according to Flashpoint  was rectified, only to be subsequently reverted in later Linux distributions. "An attacker can use cpio package to gain incorrect access to any other user accounts," Zimbra said in an advisory published last week, adding it "recommends pax over cpio." Fixes are available in the following versions - Zimbra 9.0.0 Patch 27 Zimbra 8.8.15 Patch 34 All an adversary seeking needs ...
