Quest KACE has a year-old maximum-severity authentication bypass (CVE-2025-32975, CVSS 10.0). Hunt.io researchers now report that an attacker exploited an unpatched KACE appliance at a Boston-area managed services provider called HIQ - then left their entire toolkit on a publicly accessible server with directory listing turned on. The exfiltrated 512 MB MariaDB dump turned out to contain the full appliance-managed endpoint list for over 60 named client organizations spanning law enforcement, government, healthcare, education, and private companies. None of those 60-plus organizations had any KACE relationship of their own - they were just customers of the MSP that ran it unpatched.
CISA added eight actively-exploited vulnerabilities to its Known Exploited Vulnerabilities catalog on April 20, with federal agencies required to patch three Cisco Catalyst SD-WAN Manager flaws by today, April 23, and the remaining five by May 4. The Cisco trio (CVE-2026-20122, CVE-2026-20128, CVE-2026-20133) enable arbitrary file upload with vmanage user privileges, recovery of stored credentials for the DCA user, and unauthenticated disclosure of sensitive configuration data. Cisco confirmed exploitation of the first two in March 2026. The other five cover a wide blast radius: CVE-2025-32975 is a CVSS 10.0 authentication bypass in Quest KACE Systems Management Appliance letting attackers impersonate any user without credentials, exploited in the wild by unknown actors last month per Arctic Wolf. CVE-2023-27351 is the PaperCut NG/MF bypass that Microsoft's Lace Tempest chained into Cl0p and LockBit deployments back in 2023. CVE-2024-27199 is a path traversal in JetBrains TeamCity giving limited admin actions - its sibling CVE-2024-27198 is already on the KEV list. CVE-2025-48700 is a Zimbra XSS that the Ukrainian CERT attributes to UAC-0233/UAC-0250 for stealing mailbox contents, MFA backup codes, and application passwords. CVE-2025-2749 is a Kentico Xperience Staging Sync Server path traversal.
