CISA Warns of Actively Exploited Adobe Acrobat Reader Vulnerability

CISA Warns of Actively Exploited Adobe Acrobat Reader Vulnerability

Oct 11, 2023 Vulnerability / Exploit
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
Critical Adobe ColdFusion Flaw Added to CISA's Exploited Vulnerability Catalog

Critical Adobe ColdFusion Flaw Added to CISA's Exploited Vulnerability Catalog

Aug 22, 2023 Vulnerability / Cyber Threat
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

Cybersecurity Tactics FinServ Institutions Can Bank On in 2024

Feb 14, 2024Financial Security / Cyber Threats
The landscape of cybersecurity in financial services is undergoing a rapid transformation. Cybercriminals are exploiting advanced technologies and methodologies, making traditional security measures obsolete. The challenges are compounded for community banks that must safeguard sensitive financial data against the same level of sophisticated threats as larger institutions, but often with more limited resources. The FinServ Threat Landscape Recent trends show an alarming increase in sophisticated cyber-attacks. Cybercriminals now deploy advanced techniques like deep fake technology and AI-powered attacks, making it increasingly difficult for banks to differentiate between legitimate and malicious activities. These developments necessitate a shift towards more sophisticated and adaptive cybersecurity measures. Take these industry statistics, for example. Financial firms report 703 cyberattack attempts per week.1 On average, 270 attacks (entailing unauthorized access of data, appl

CISA Adds Citrix ShareFile Flaw to KEV Catalog Due to In-the-Wild Attacks

Aug 17, 2023 Vulnerability / Enterprise Security
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

CISA Adds Microsoft .NET Vulnerability to KEV Catalog Due to Active Exploitation

CISA Adds Microsoft .NET Vulnerability to KEV Catalog Due to Active Exploitation

Aug 11, 2023 Endpoint Security / Vulnerability
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

U.S. Cybersecurity Agency Adds 6 Flaws to Known Exploited Vulnerabilities Catalog

Jun 24, 2023 Threat Intel / Zero Day
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.

Feb 11, 2023 Threat Response / Vulnerability
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
