CVE ID |
CVE-2025-20352 |
Impact |
A third-party vulnerability exists in the affected products. The affected products use Cisco IOS XE Software which contains a vulnerability in the Simple Network Management Protocol (SNMP) subsystem. An authenticated, remote attacker with low privileges could cause a denial of service (DoS) condition on an affected device that is running Cisco IOS Software or Cisco IOS XE Software. To cause the DoS, the attacker must have the SNMPv2c or earlier read-only community string or valid SNMPv3 user credentials. An authenticated, remote attacker with high privileges could execute code as the root user on an affected device that is running Cisco IOS XE Software. To execute code as the root user, the attacker must have the SNMPv1 or v2c read-only community string or valid SNMPv3 user credentials and administrative or privilege 15 credentials on the affected device. An attacker could exploit this vulnerability by sending a crafted SNMP packet to an affected device over IPv4 or IPv6 networks. This vulnerability is due to a stack overflow condition in the SNMP subsystem of the affected software. 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. Note: This vulnerability affects all versions of SNMP. |

Glossary
- Simple Network Management Protocol (SNMP): Used for collecting and organizing information about managed devices on IP.
- Stack overflow: A runtime error that occurs when a program uses more stack memory than is available, typically due to excessive or infinite recursion or deeply nested function calls.
- Denial of Service (DoS): A malicious attempt to disrupt the normal functioning of a targeted server, service, or network by overwhelming it with a flood of traffic or triggering a crash.
- Cisco IOS (Internetwork Operating System): Proprietary software used on most Cisco routers and switches, providing the command-line interface and network services necessary for configuring, managing, and operating Cisco networking devices.
- Cisco IOS XE: A modern, modular operating system built on a Linux kernel that powers Cisco enterprise networking devices, offering enhanced programmability, security, and scalability while maintaining compatibility with traditional IOS command-line interfaces..
