CVE-2015-7848

21
FAUCET Score

CVE-2015-7848 describes an integer overflow vulnerability in NTP-dev.4.3.70, specifically affecting NetApp and NTP products. This flaw allows an unauthenticated attacker to trigger an out-of-bounds memory copy, leading to a denial-of-service condition (immediate crash) of the NTP daemon by sending a specially crafted private mode packet with a valid MAC and timestamp. While rated as high severity (CVSS 7.5) due to its network attack vector and low complexity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
