VMware has  released  security updates to fix a trio of flaws in Aria Operations for Networks that could result in information disclosure and remote code execution. The most critical of the three vulnerabilities is a command injection vulnerability tracked as  CVE-2023-20887  (CVSS score: 9.8) that could allow a malicious actor with network access to achieve remote code execution. Also patched by VMware is another  deserialization vulnerability  ( CVE-2023-20888 ) that's rated 9.1 out of a maximum of 10 on the CVSS scoring system. "A malicious actor with network access to VMware Aria Operations for Networks and valid 'member' role credentials may be able to perform a deserialization attack resulting in remote code execution," the company said in an advisory. The third security defect is a high-severity information disclosure bug ( CVE-2023-20889 , CVSS score: 8.8) that could permit an actor with network access to perform a command injection attack and obtain

Enterprise security company Barracuda is now urging customers who were impacted by a recently disclosed zero-day flaw in its Email Security Gateway (ESG) appliances to immediately replace them. "Impacted ESG appliances must be immediately replaced regardless of patch version level," the company  said  in an update, adding its "remediation recommendation at this time is full replacement of the impacted ESG." While the company did not disclose the reasons behind the move, it's likely an indication that the threat actors behind the campaign managed to tamper with the firmware on a much deeper level that a patch cannot completely address. The latest development comes as Barracuda  disclosed  that a critical flaw in the devices (CVE-2023-2868, CVSS score: 9.8) had been exploited as a zero-day for at least seven months since October 2022 to deliver bespoke malware and steal data. The  vulnerability  concerns a case of remote code injection affecting versions 5.1

A critical flaw in Progress Software's in MOVEit Transfer managed file transfer application has come under widespread exploitation in the wild to take over vulnerable systems. The shortcoming, which is assigned the CVE identifier CVE-2023-34362 , relates to a severe SQL injection vulnerability that could lead to escalated privileges and potential unauthorized access to the environment. "An SQL injection vulnerability has been found in the MOVEit Transfer web application that could allow an unauthenticated attacker to gain unauthorized access to MOVEit Transfer's database," the company  said . "Depending on the database engine being used (MySQL, Microsoft SQL Server, or Azure SQL), an attacker may be able to infer information about the structure and contents of the database in addition to executing SQL statements that alter or delete database elements." Patches for the bug have been made available by the Massachusetts-based company, which also owns Teler

Cybersecurity researchers have found "backdoor-like behavior" within Gigabyte systems, which they say enables the  UEFI firmware  of the devices to drop a Windows executable and retrieve updates in an unsecure format. Firmware security firm Eclypsium  said  it first detected the anomaly in April 2023. Gigabyte has since acknowledged and addressed the issue. "Most Gigabyte firmware includes a Windows Native Binary executable embedded inside of the UEFI firmware," John Loucaides, senior vice president of strategy at Eclypsium, told The Hacker News. "The detected Windows executable is dropped to disk and executed as part of the Windows startup process, similar to the  LoJack double agent attack . This executable then downloads and runs additional binaries via insecure methods." "Only the intention of the author can distinguish this sort of vulnerability from a malicious backdoor," Loucaides added. The executable, per Eclypsium, is embedded in

Microsoft has shared details of a now-patched flaw in Apple macOS that could be abused by threat actors with root access to bypass security enforcements and perform arbitrary actions on affected devices. Specifically, the flaw – dubbed  Migraine  and tracked as CVE-2023-32369 – could be abused to get around a key security measure called System Integrity Protection ( SIP ), or "rootless," which limits the actions the root user can perform on protected files and folders. "The most straight-forward implication of a SIP bypass is that [...] an attacker can create files that are protected by SIP and therefore undeletable by ordinary means," Microsoft researchers Jonathan Bar Or, Michael Pearse, and Anurag Bohra  said . Even worse, it could be exploited to gain arbitrary kernel code execution and even access sensitive data by replacing databases that manage Transparency, Consent, and Control (TCC) policies. The bypass is made possible by leveraging a built-in macOS tool called  Migrat

Enterprise security firm Barracuda on Tuesday disclosed that a recently patched zero-day flaw in its Email Security Gateway (ESG) appliances had been abused by threat actors since October 2022 to backdoor the devices. The latest  findings  show that the  critical vulnerability , tracked as  CVE-2023-2868  (CVSS score: N/A), has been actively exploited for at least seven months prior to its discovery. The flaw, which Barracuda identified on May 19, 2023, affects versions 5.1.3.001 through 9.2.0.006 and could allow a remote attacker to achieve code execution on susceptible installations. Patches were released by Barracuda on May 20 and May 21. "CVE-2023-2868 was utilized to obtain unauthorized access to a subset of ESG appliances," the network and email security company  said  in an updated advisory. "Malware was identified on a subset of appliances allowing for persistent backdoor access. Evidence of data exfiltration was identified on a subset of impacted appliance

If you're a cybersecurity professional, you're likely familiar with the sea of acronyms our industry is obsessed with. From CNAPP, to CWPP, to CIEM and all of the myriad others, there seems to be a new initialism born each day. In this article, we'll look at another trending acronym – CTEM, which stands for Continuous Threat Exposure Management – and the often-surprising challenges that come along with seeing a CTEM program through to maturity. While the concept of CTEM isn't brand spanking new, having made its in-print debut in July of 2022, we are now at the point where many organizations are starting to try to operationalize the programs that they've been setting into motion over the last few months. And as organizations start to execute their carefully designed plans, they may find themselves bumping up against some unexpected challenges which can lead to setbacks.  What is Continuous Threat Exposure Management (CTEM)? But first, to backtrack, let's just

A critical security vulnerability has been disclosed in the Open Authorization (OAuth) implementation of the application development framework Expo.io. The shortcoming, assigned the CVE identifier  CVE-2023-28131 , has a severity rating of 9.6 on the CVSS scoring system. API security firm Salt Labs  said  the issue rendered services using the framework susceptible to credential leakage, which could then be used to hijack accounts and siphon sensitive data. Under certain circumstances, a threat actor could have taken advantage of the flaw to perform arbitrary actions on behalf of a compromised user on various platforms such as Facebook, Google, or Twitter. Expo, similar to Electron, is an open source platform for developing universal native apps that run on Android, iOS, and the web. It's worth noting that for the attack to be successful, sites and applications using Expo should have configured the AuthSession Proxy setting for single sign-on (SSO) using a third-party provider

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 remotely exe

The second generation version of Belkin's Wemo Mini Smart Plug has been found to contain a buffer overflow vulnerability that could be weaponized by a threat actor to inject arbitrary commands remotely. The issue, assigned the identifier  CVE-2023-27217 , was discovered and reported to Belkin on January 9, 2023, by Israeli IoT security company Sternum , which reverse-engineered the device and gained firmware access. Wemo Mini Smart Plug V2 ( F7C063 ) offers convenient remote control, allowing users to turn electronic devices on or off using a companion app installed on a smartphone or tablet. The heart of the problem lies in a feature that makes it possible to rename the smart plug to a more " FriendlyName ." The default name assigned is " Wemo mini 6E9 ." "The name length is limited to 30 characters or less, but this rule is only enforced by the app itself," security researchers Amit Serper and Reuven Yakar  said  in a report shared with The Hac

U.S. cybersecurity and intelligence agencies have warned of attacks carried out by a threat actor known as the  Bl00dy Ransomware Gang  that attempt to exploit vulnerable PaperCut servers against the education facilities sector in the country. The attacks took place in early May 2023, the Federal Bureau of Investigation (FBI) and Cybersecurity and Infrastructure Security Agency (CISA) said in a joint cybersecurity advisory issued Thursday. "The Bl00dy Ransomware Gang gained access to victim networks across the Education Facilities Subsector where PaperCut servers vulnerable to  CVE-2023-27350  were exposed to the internet," the agencies  said . "Ultimately, some of these operations led to data exfiltration and encryption of victim systems. The Bl00dy Ransomware Gang left ransom notes on victim systems demanding payment in exchange for decryption of encrypted files." Additionally, the Bl00dy actors are said to have used TOR and other proxies from within victim

A security vulnerability has been disclosed in the popular WordPress plugin  Essential Addons for Elementor  that could be potentially exploited to achieve elevated privileges on affected sites. The issue, tracked as CVE-2023-32243, has been addressed by the plugin maintainers in version 5.7.2 that was shipped on May 11, 2023.
