Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for curl/curl, curl/curl, Siemens/RUGGEDCOM RST2428P.
  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.

Upstream source description

When curl is told to use the Certificate Status Request TLS extension, often referred to as OCSP stapling, to verify that the server certificate is valid, it might fail to detect some OCSP problems and instead wrongly consider the response as fine. If the returned status reports another error than 'revoked' (like for example 'unauthorized') it is not treated as a bad certficate.
