CVSS v3.1
Official Description
Heap-based buffer overflow in the RPC subsystem in Symantec Backup Exec for Windows Servers 10.0, 10d, and 11d allows remote attackers to cause a denial of service (process exit) and possibly execute arbitrary code via crafted ncacn_ip_tcp requests.
Technical Analysis
CVE-2007-3509 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
