Pulse Secure VPN | Breaking Cybersecurity News | The Hacker News

Ivanti, the company behind Pulse Secure VPN appliances, has published a security advisory for a high severity vulnerability that may allow an authenticated remote attacker to execute arbitrary code with elevated privileges. "Buffer Overflow in Windows File Resource Profiles in 9.X allows a remote authenticated user with privileges to browse SMB shares to execute arbitrary code as the root user," the company  said  in an alert published on May 14. "As of version 9.1R3, this permission is not enabled by default." The flaw, identified as CVE-2021-22908, has a CVSS score of 8.5 out of a maximum of 10 and impacts Pulse Connect Secure versions 9.0Rx and 9.1Rx. In a report detailing the vulnerability, the CERT Coordination Center said the issue stems from the gateway's ability to connect to Windows file shares through a number of CGI endpoints that could be leveraged to carry out the attack. "When specifying a long server name for some SMB operations, the 

Ivanti, the company behind Pulse Secure VPN appliances, has released a security patch to remediate a critical security vulnerability that was found being actively exploited in the wild by at least two different threat actors. Tracked as  CVE-2021-22893  (CVSS score 10), the flaw concerns "multiple use after free" issues in Pulse Connect Secure that could allow a remote unauthenticated attacker to execute arbitrary code and take control of the affected system. All Pulse Connect Secure versions prior to 9.1R11.4 are impacted. The flaw came to light on April 20 after FireEye  disclosed  a series of intrusions targeting defense, government, and financial organizations in the U.S. and elsewhere by leveraging critical vulnerabilities in the remote access solution to bypass multi-factor authentication protections and breach enterprise networks. The development promoted the U.S. Cybersecurity and Infrastructure Security Agency (CISA) to issue an  Emergency Directive  urging fede

As cloud technology evolves, so does the challenge of securing sensitive data. In a world where data duplication and sprawl are common, organizations face increased risks of non-compliance and unauthorized data breaches. Sentra's DSPM (Data Security Posture Management) emerges as a comprehensive solution, offering continuous discovery and accurate classification of sensitive data in the cloud. This informative webinar, " Securing Sensitive Data Starts with Discovery and Classification: SoFi's DSPM Story " unveils the success story of SoFi, a pioneering cloud-native financial services provider, and its journey with Sentra's DSPM. It explores the challenges and triumphs in securing cloud data and a roadmap to implementing effective DSPM strategies in your organization.

The US Cybersecurity and Infrastructure Security Agency (CISA) issued a new advisory on Monday about a wave of cyberattacks carried by Chinese nation-state actors targeting US government agencies and private entities. "CISA has observed Chinese [Ministry of State Security]-affiliated cyber threat actors operating from the People's Republic of China using commercially available information sources and open-source exploitation tools to target US Government agency networks," the cybersecurity agency said. Over the past 12 months, the victims were identified through sources such as Shodan , the Common Vulnerabilities and Exposure ( CVE ) database, and the National Vulnerabilities Database (NVD), exploiting the public release of a vulnerability to pick vulnerable targets and further their motives. By compromising legitimate websites and leveraging spear-phishing emails with malicious links pointing to attacker-owned sites in order to gain initial access, the Chinese

The United States Cybersecurity and Infrastructure Security Agency (CISA) yesterday issued a fresh advisory alerting organizations to change all their Active Directory credentials as a defense against cyberattacks trying to leverage a known remote code execution (RCE) vulnerability in Pulse Secure VPN servers—even if they have already patched it. The warning comes three months after another CISA alert urging users and administrators to patch Pulse Secure VPN environments to thwart attacks exploiting the vulnerability. "Threat actors who successfully exploited CVE-2019-11510 and stole a victim organization's credentials will still be able to access — and move laterally through — that organization's network after the organization has patched this vulnerability if the organization did not change those stolen credentials," CISA said. CISA has also released a tool to help network administrators look for any indicators of compromise associated with the flaw.
