Cisco IOS Software SNMP Remote Code Execution Vulnerability

Added to KEV: 2022-03-03Federal patch deadline: 2022-03-24

Required Action (CISA)

Apply updates per vendor instructions.

Risk Analysis

This vulnerability in Cisco IOS SNMP allows an authenticated, remote attacker to execute code or cause a system reload by sending a specially crafted SNMP packet. The high EPSS score and confirmed exploitation indicate a significant and active threat that requires immediate attention.

This vulnerability has been actively exploited in the wild and is listed in CISA's KEV catalog, confirming its active use by attackers. Its remote exploitability via network makes it a critical concern.

Recommended Action

Administrators should apply available patches or upgrades for Cisco IOS to address this SNMP vulnerability. Restricting SNMP access to trusted networks and implementing strong authentication for SNMP can also reduce risk.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2017-6744 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

CISA has added CVE-2017-6744 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
