CVE-2013-20004Network attack vector

Service interruption via unbounded connection allocation

Published Feb 6, 2022 · Updated Aug 6, 2024

Denial of service in StarWind iSCSI SAN (Windows Native) 6.0 build 2013-01-16 allows remote attackers to exhaust server memory. The iSCSI target service accepts unlimited connection attempts to a nonexistent target and allocates memory for every attempt. Network access to the service is sufficient; sustained attempts deplete memory until the iSCSI target becomes nonfunctional.
