The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday  added  a high-severity flaw in Adobe Acrobat Reader to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. Tracked as  CVE-2023-21608  (CVSS score: 7.8), the vulnerability has been described as a use-after-free bug that can be exploited to achieve remote code execution (RCE) with the privileges of the current user. A patch for the flaw was released by Adobe in January 2023. HackSys security researchers Ashfaq Ansari and Krishnakant Patil were  credited  with discovering and reporting the flaw. The  following versions  of the software are impacted - Acrobat DC - 22.003.20282 (Win), 22.003.20281 (Mac) and earlier versions (fixed in 22.003.20310) Acrobat Reader DC - 22.003.20282 (Win), 22.003.20281 (Mac) and earlier versions (fixed in 22.003.20310) Acrobat 2020 - 20.005.30418 and earlier versions (fixed in 20.005.30436) Acrobat Reader 2020 - 20.005.30418 and earl

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has  added  a critical security flaw in Adobe ColdFusion to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerability, cataloged as  CVE-2023-26359  (CVSS score: 9.8), relates to a deserialization flaw present in Adobe ColdFusion 2018 (Update 15 and earlier) and ColdFusion 2021 (Update 5 and earlier) that could result in arbitrary code execution in the context of the current user without requiring any interaction. Deserialization  (aka unmarshaling) refers to the process of reconstructing a data structure or an object from a byte stream. But when it's performed without validating its source or sanitizing its contents, it can lead to  unexpected consequences  such as code execution or denial-of-service (DoS). It was  patched  by Adobe as part of updates issued in March 2023. As of writing, it's immediately not clear how the flaw is being  abused in the wil

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a critical security flaw in Citrix ShareFile storage zones controller to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active in-the-wild exploitation. Tracked as  CVE-2023-24489  (CVSS score: 9.8), the shortcoming has been described as an improper access control bug that, if successfully exploited, could allow an unauthenticated attacker to compromise vulnerable instances remotely. The problem is rooted in ShareFile's handling of cryptographic operations, enabling adversaries to upload arbitrary files, resulting in remote code execution. "This vulnerability affects all currently supported versions of customer-managed ShareFile storage zones controller before version 5.11.24," Citrix  said  in an advisory released in June. Dylan Pindur of Assetnote has been credited with discovering and reporting the issue. It's worth noting that the  first signs of exploitatio

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has  added  a recently patched security flaw in Microsoft's .NET and Visual Studio products to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. Tracked as  CVE-2023-38180  (CVSS score: 7.5), the high-severity flaw relates to a case denial-of-service (DoS) impacting .NET and Visual Studio. It was  addressed  by Microsoft as part of its August 2023 Patch Tuesday updates shipped earlier this week, tagging it with an "Exploitation More Likely" assessment. While exact details surrounding the nature of exploitation are unclear, the Windows maker has acknowledged the existence of a proof-of-concept (PoC) in its advisory. It also said that attacks leveraging the flaw can be pulled off without any additional privileges or user interaction. "Proof-of-concept exploit code is available, or an attack demonstration is not practical for most systems," the company 

The U.S. Cybersecurity and Infrastructure Security Agency has  added  a batch of six flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. This comprises three vulnerabilities that Apple patched this week ( CVE-2023-32434, CVE-2023-32435, and CVE-2023-32439 ), two flaws in VMware ( CVE-2023-20867  and  CVE-2023-20887 ), and one shortcoming impacting Zyxel devices ( CVE-2023-27992 ). CVE-2023-32434 and CVE-2023-32435, both of which allow code execution, are said to have been exploited as zero-days to deploy spyware as part of a years-long cyber espionage campaign that commenced in 2019. Dubbed Operation Triangulation, the activity culminates in the deployment of  TriangleDB  that's designed to harvest a wide range of information from compromised devices, such as creating, modifying, removing, and stealing files, listing and terminating processes, gathering credentials from iCloud Keychain, and tracking a user's location. The

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday  added  three flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active abuse in the wild. Included among the three is  CVE-2022-24990 , a bug affecting TerraMaster network-attached storage (TNAS) devices that could lead to unauthenticated remote code execution with the highest privileges. Details about the flaw were  disclosed  by Ethiopian cyber security research firm Octagon Networks in March 2022. The vulnerability, according to a  joint advisory  released by U.S. and South Korean government authorities, is said to have been weaponized by North Korean nation-state hackers to strike healthcare and critical infrastructure entities with ransomware. The second shortcoming to be added to KEV catalog is  CVE-2015-2291 , an unspecified flaw in the Intel ethernet diagnostics driver for Windows (IQVW32.sys and IQVW64.sys) that could throw an affected device into a denial-of-service

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday  added  a recently disclosed security flaw in Zoho ManageEngine to its Known Exploited Vulnerabilities ( KEV ) Catalog, citing evidence of active exploitation. "Zoho ManageEngine PAM360, Password Manager Pro, and Access Manager Plus contain an unspecified vulnerability which allows for remote code execution," the agency said in a notice. The  critical vulnerability , tracked as  CVE-2022-35405 , is rated 9.8 out of 10 for severity on the CVSS scoring system, and was patched by Zoho as part of updates released on June 24, 2022. Although the exact nature of the flaw remains unknown, the India-based enterprise solutions company  said  it addressed the issue by removing the vulnerable components that could lead to the remote execution of arbitrary code. Zoho has also warned of the public availability of a proof-of-concept (PoC) exploit for the vulnerability, making it imperative that customers move
