1. EXECUTIVE SUMMARY CVSS v4 6.3 ATTENTION: Exploitable remotely/Low attack complexity Vendor: Rockwell Automation Equipment: Stratix 5700, 5400, 5410, 5200, 5800 Vulnerability: Stack-based Buffer Overflow
2. RISK EVALUATION Successful exploitation of this vulnerability could result in arbitrary code execution.
3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following version of Stratix 5700 is affected: Stratix 5700: Version v15.2(8)E7 and prior Stratix 5400: Version v15.2(8)E7 and prior Stratix 5410: Version v15.2(8)E7 and prior Stratix 5200: Version v17.17.01 and prior Stratix 5800: Version v17.17.01 and prior 3.2 VULNERABILITY OVERVIEW 3.2.1 STACK-BASED BUFFER OVERFLOW CWE-121 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 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 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. CVE-2025-20352 has been assigned to this vulnerability. A CVSS v3 base score of 7.7 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H). A CVSS v4 score has also been calculated for CVE-2025-20352. A base score of 6.3 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:H). 3.3 BACKGROUND CRITICAL INFRASTRUCTURE SECTORS: Critical Manufacturing COUNTRIES/AREAS DEPLOYED: Worldwide COMPANY HEADQUARTERS LOCATION: United States 3.4 RESEARCHER Rockwell Automation reported this vulnerability to CISA.
4. MITIGATIONS Rockwell Automation recommends users of the affected Stratix software implement workarounds from Cisco and our security best practices. For more information about this issue, see the advisory on the Rockwell Automation security page. CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as: Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents. No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time.
