A zero-day flaw in the Zimbra Collaboration email software was exploited by four different groups in real-world attacks to pilfer email data, user credentials, and authentication tokens. "Most of this activity occurred after the initial fix became public on GitHub," Google Threat Analysis Group (TAG)  said  in a report shared with The Hacker News. The flaw, tracked as  CVE-2023-37580  (CVSS score: 6.1), is a  reflected cross-site scripting  (XSS) vulnerability impacting versions before 8.8.15 Patch 41. It was  addressed  by Zimbra as part of patches released on July 25, 2023. Successful exploitation of the shortcoming could allow execution of malicious scripts on the victims' web browser simply by tricking them into clicking on a specially crafted URL, effectively initiating the XSS request to Zimbra and reflecting the attack back to the user. Google TAG, whose researcher Clément Lecigne was credited with discovering and reporting the bug, s...

Networking equipment major Cisco has rolled out software updates to address multiple critical vulnerabilities impacting HyperFlex HX and SD-WAN vManage Software that could allow an attacker to perform command injection attacks, execute arbitrary code, and gain access to sensitive information. In a series of advisories published on May 5, the company said there are no workarounds that remediate the issues. The HyperFlex HX command injection vulnerabilities, tracked as CVE-2021-1497 and CVE-2021-1498 (CVSS scores 9.8), affect all Cisco devices running HyperFlex HX software versions 4.0, 4.5, and those prior to 4.0. Arising due to insufficient validation of user-supplied input in the web-based management interface of Cisco HyperFlex HX Data Platform, the flaws could enable an unauthenticated, remote attacker to perform a command injection attack against a vulnerable device. "An attacker could exploit this vulnerability by sending a crafted request to the web-based management int...

As SaaS providers race to integrate AI into their product offerings to stay competitive and relevant, a new challenge has emerged in the world of AI: shadow AI.  Shadow AI refers to the unauthorized use of AI tools and copilots at organizations. For example, a developer using ChatGPT to assist with writing code, a salesperson downloading an AI-powered meeting transcription tool, or a customer support person using Agentic AI to automate tasks – without going through the proper channels. When these tools are used without IT or the Security team's knowledge, they often lack sufficient security controls, putting company data at risk. Shadow AI Detection Challenges Because shadow AI tools often embed themselves in approved business applications via AI assistants, copilots, and agents they are even more tricky to discover than traditional shadow IT. While traditional shadow apps can be identified through network monitoring methodologies that scan for unauthorized connections based on...
