CVE-2024-3596
View CSAF Summary Schneider Electric is aware of a RADIUS protocol vulnerability affecting its Modicon Network Managed Switch product. The Modicon Network Managed Switch product provides connectivi...
Affects 4 products across 7 vendors.
Mapping is CWE-to-CAPEC per MITRE CAPEC 3.9.
The RADIUS protocol, as defined in RFC 2865, is vulnerable to forgery attacks where a local attacker can modify valid responses (Access-Accept, Access-Reject, or Access-Challenge) using a chosen-prefix collision attack against the MD5 Response Authenticator signature. This vulnerability has a CVSS score of 9.0, indicating high severity, and affects multiple vendors including Broadcom, Freeradius, Fujitsu-Siemens, Schneider-Electric, Siemens, Sonicwall, and Wolfram Schneider. While there is no known exploit, a public proof of concept exists, and the EPSS score suggests a low likelihood of exploitation in the wild. However, given the critical nature of authentication in ICS/OT environments, immediate attention is required to mitigate this risk.
BSID: BS-2024-GLOBAL-266372-C • Model: Qwen/Qwen2.5-72B-Instruct-AWQ • Confidence: HIGH

View CSAF Summary Schneider Electric is aware of a RADIUS protocol vulnerability affecting its Modicon Network Managed Switch product. The Modicon Network Managed Switch product provides connectivity for multiple Ethernet devices, network management, enhanced cyber security and more advanced switching features. Failure to apply the mitigation provided below may risk forgery attacks in RADIUS Protocol, which could result in modification of any valid Response (Access-Accept, Access-Reject, or Acce
Source: NIST NVD / MITRE CVE Database
A local attacker can exploit this vulnerability by intercepting and modifying valid RADIUS responses (Access-Accept, Access-Reject, or Access-Challenge) using a chosen-prefix collision attack against the MD5 Response Authenticator signature. This allows the attacker to forge responses, potentially leading to unauthorized access or denial of service. The attack requires network access and knowledge of the RADIUS protocol, but does not require user interaction or specific privileges.

Implement strong network segmentation to isolate RADIUS servers from untrusted networks. Use secure communication channels (e.g., TLS) for RADIUS traffic to prevent interception and modification. Regularly monitor RADIUS logs for suspicious activity.
No reliable network detection signature exists for this vulnerability class — apply the compensating controls above and the vendor patch. SAGE only publishes a network rule when a concrete on-the-wire signature can be grounded in the advisory.
This CVE violates CIP-007-R2 because it involves the potential for unauthorized access to electronic security perimeters, which could compromise the integrity and availability of critical cyber assets.
This CVE maps to SR 7.6 because it involves the protection of authentication mechanisms, which are essential for maintaining the security of industrial control systems and preventing unauthorized access.
Virtual patch generated by CITED Relevance SAGE. Validate in isolated environment before production deployment. Compensating control only - does not replace vendor patch.
