CVE-2024-37992 Siemens CVE debrief

A vulnerability in Siemens SIMATIC RFID readers allows an authenticated attacker to trigger an application restart by sending SNMP configuration data that exceeds character limits. The affected devices do not properly handle this error condition, resulting in denial of service. The vulnerability requires network access and administrative privileges (PR:H), with a CVSS 3.1 score of 4.9 (MEDIUM). Twenty-seven product variants across the SIMATIC Reader RF610R, RF615R, RF650R, RF680R, RF685R, RF1140R, RF1170R, RF166C, RF185C, RF186C, RF186CI, RF188C, RF188CI, and RF360R series are affected. Siemens has released firmware updates to address this issue, with version requirements varying by product family.

Who should care

Organizations operating Siemens SIMATIC RFID readers in industrial environments, particularly those with remote SNMP management enabled. Asset owners in manufacturing, logistics, and supply chain operations relying on continuous RFID availability should prioritize patching during maintenance windows.

Technical summary

The vulnerability exists in the SNMP configuration handling of affected SIMATIC RFID readers. When SNMP settings containing excessive character counts are submitted, the device fails to handle the resulting error gracefully, causing the application to restart. This represents an improper error handling weakness (CWE-755) in the device's management interface. The attack requires network connectivity to the device's SNMP service and valid administrative credentials. Successful exploitation results in temporary loss of RFID reader functionality until the application completes its restart cycle. No confidentiality or integrity impacts are associated with this vulnerability.
