Security News > 2023 > February > CISA Issues Warning on Active Exploitation of ZK Java Web Framework Vulnerability
The U.S. Cybersecurity and Infrastructure Security Agency has added a high-severity flaw affecting the ZK Framework to its Known Exploited Vulnerabilities catalog based on evidence of active exploitation.
Tracked as CVE-2022-36537, the issue impacts ZK Framework versions 9.6.1, 9.6.0.1, 9.5.1.3, 9.0.1.2, and 8.6.4.1, and allows threat actors to retrieve sensitive information via specially crafted requests.
"The ZK Framework is an open source Java framework," CISA said.
"This vulnerability can impact multiple products, including but not limited to ConnectWise R1Soft Server Backup Manager."
The vulnerability was patched in May 2022 in versions 9.6.2, 9.6.0.2, 9.5.1.4, 9.0.1.3, and 8.6.4.2.
The vulnerability has since come under mass exploitation, as evidenced by NCC Group's Fox-IT research team last week, to obtain initial access and deploy a web shell backdoor on 286 servers.
