CVE-2005-2177
CWE-20Published: July 11, 2005· Updated: Jun 16, 2026
5.0
CVSS v3.1
Official Description
Net-SNMP 5.0.x before 5.0.10.2, 5.2.x before 5.2.1.2, and 5.1.3, when net-snmp is using stream sockets such as TCP, allows remote attackers to cause a denial of service (daemon hang and CPU consumption) via a TCP packet of length 1, which triggers an infinite loop.
Technical Analysis
CVE-2005-2177 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.
