Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Multiple Siemens SIMATIC RFID reader devices contain a vulnerability where service log files can be accessed without proper authentication. An unauthenticated attacker with network access could retrieve sensitive information from these exposed log files.

MitigationUpdate the affected devices to the specified fixed versions (V4.2 for RF610R/RF615R/RF650R/RF680R/RF685R models; V1.1 for RF1140R/RF1170R; V2.2 for RF166C/RF185C/RF186C/RF186CI/RF188C/RF188CI/RF360R) as listed in the Siemens advisory.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the RFID reader model
    Locate the device physically or check network inventory for the SIMATIC RFID reader model number (e.g., RF360R, RF1170R, RF1140R, RF680R, RF685R)
    Affected if The model is one of: RF360R, RF1170R, RF1140R, RF680R, or RF685R (any variant)
  2. Determine the installed firmware version
    Access the device web interface or use the device's management console to view the firmware version information
    Affected if The firmware version is lower than the affected threshold for that model (RF360R < 2.2, RF1170R < 1.1, RF1140R < 1.1, RF680R < 4.2, RF685R < 4.2)
  3. Verify network accessibility
    Confirm the device is reachable on the network from an untrusted segment or external network
    Affected if The device is accessible from a network segment where unauthenticated attackers could reach it
  4. Check for exposed log file paths
    Attempt to access common log file URLs or paths on the device web interface (e.g., /logs/, /service/logs/, or similar paths) without authentication
    Affected if Log files are returned without requiring authentication credentials

A user is affected if they have a SIMATIC RFID reader (RF360R, RF1170R, RF1140R, RF680R, or RF685R) running firmware below the fixed version threshold AND the device is network-accessible to unauthenticated attackers.

dbcve · scoped
Upgrade available Upgrade to 1.1 / 2.2 / 4.2 or later
Fixed in 1.12.24.2
Interim mitigation

Update the affected devices to the specified fixed versions (V4.2 for RF610R/RF615R/RF650R/RF680R/RF685R models; V1.1 for RF1140R/RF1170R; V2.2 for RF166C/RF185C/RF186C/RF186CI/RF188C/RF188CI/RF360R) as listed in the Siemens advisory.

Recommended fix High confidence

Upgrade to firmware version V2.2 for RF360R/RF166C/RF185C/RF186C/RF186CI/RF188C/RF188CI; V1.1 for RF1140R/RF1170R; V4.2 for all RF610R/RF615R/RF650R/RF680R/RF685R readers

  1. 1. Identify the exact model number and current firmware version of the affected SIMATIC RFID device from the Siemens product list.
  2. 2. Download the latest firmware update from Siemens Industry Online Support (support.industry.siemens.com) or the cert-portal.siemens.com reference.
  3. 3. Review the firmware release notes to confirm the version includes the CVE-2024-37991 security fix.
  4. 4. Follow Siemens standard firmware update procedures for the specific device (typically via TIA Portal, Web Based Management, or PC-based update tool).
  5. 5. After upgrading, verify that the service log files are no longer accessible without authentication.
  6. 6. Confirm the device is running the minimum fixed version: RF360R: V2.2, RF1140R: V1.1, RF1170R: V1.1, RF680R/RF685R: V4.2, and other listed readers: V4.2.
