Kaseya

Kaseya develops remote monitoring, management, and backup software that sits at the heart of managed service provider (MSP) operations, where a single compromise can affect thousands of downstream customer environments. Vulnerabilities affecting the vendor skew strongly toward critical-severity outcomes and frequently acquire public exploit code, creating outsized risk relative to the vendor's narrow product footprint. The exposure concentrates in flagship products such as VSA, Virtual System Administrator, and Unitrends Backup and recurs through weakness classes including improper authentication, path traversal, and SQL injection that expose administrative interfaces and backup systems to unauthorized access and data exfiltration. Defenders should treat Kaseya disclosures as supply-chain critical and prioritize patching on internet-facing instances; live exploitation activity and severity counts are shown alongside this summary.
