Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for curl/curl, Siemens/RUGGEDCOM RST2428P, Siemens/SCALANCE XC-300/XR-300/XC-400/XR-500WG/XR-500 family.
  2. 2Review the reported fix. Update Siemens/RUGGEDCOM RST2428P to V3.3; Siemens/SCALANCE XC-300/XR-300/XC-400/XR-500WG/XR-500 family to V3.3; Siemens/SCALANCE XCH328 to V3.3; Siemens/SCALANCE XCM324 to V3.3; Siemens/SCALANCE XCM328 to V3.3; Siemens/SCALANCE XCM332 to V3.3; Siemens/SCALANCE XRH334 (24 V DC, 8xFO, CC) to V3.3; Siemens/SCALANCE XRM334 (230 V AC, 12xFO) to V3.3; Siemens/SCALANCE XRM334 (230V AC, 2x10G, 24xSFP, 8xSFP+) to V3.3; Siemens/SCALANCE XRM334 (230 V AC, 8xFO) to V3.3; Siemens/SCALANCE XRM334 (24 V DC, 12xFO) to V3.3; Siemens/SCALANCE XRM334 (24V DC, 2x10G, 24xSFP, 8xSFP+) to V3.3; Siemens/SCALANCE XRM334 (24 V DC, 8xFO) to V3.3; Siemens/SCALANCE XRM334 (2x230 V AC, 12xFO) to V3.3; Siemens/SCALANCE XRM334 (2x230V AC, 2x10G, 24xSFP, 8xSFP+) to V3.3; Siemens/SCALANCE XRM334 (2x230 V AC, 8xFO) to V3.3; Siemens/SIMATIC S7-1500 CPU 1518-4 PN/DP MFP to V3.1.5; Siemens/SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP to V3.1.5; Siemens/SIPLUS S7-1500 CPU 1518-4 PN/DP MFP to V3.1.5 if you use the affected versions. Test the change in a non-production environment first.
