{"schema":"threatline.record/2","record":{"id":"CVE-2025-20352","aliases":[],"summary":"Cisco IOS and IOS XE Software SNMP Denial of Service and Remote Code Execution Vulnerability","details":"Cisco IOS and IOS XE contains a stack-based buffer overflow vulnerability in the Simple Network Management Protocol (SNMP) subsystem that could allow for denial of service or remote code execution. A successful exploit could allow a low-privileged attacker to cause the affected system to reload, resulting in a DoS condition, or allow a high-privileged attacker to execute arbitrary code as the root user and obtain full control of the affected system.","categories":["Operating systems"],"product":"IOS and IOS XE","vendor":"Cisco","ecosystem":null,"affected_ranges":[{"source":"CVE
