CVE-2014-5413
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSchneider Electric StruxureWare SCADA Expert ClearSCADA 2010 R3 through 2014 R1 uses the MD5 algorithm for an X.509 certificate, which makes it easier for remote attackers to spoof servers via a cryptographic attack against this algorithm.
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 confidenceSchneider Electric StruxureWare SCADA Expert ClearSCADA versions 2010 R3 through 2014 R1 use the cryptographically weak MD5 algorithm for X.509 certificate signatures. This vulnerability allows remote attackers to create fraudulent certificates through known MD5 collision attacks, enabling server spoofing and man-in-the-middle attacks against the SCADA infrastructure.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify ClearSCADA versionCheck the installed version of ClearSCADA through the software itself (typically in Help > About or in Windows Add/Remove Programs). Look for version numbers such as 2010, 2013, 2014, or specific releases like 2010 R3 through 2014 R1.Affected if The installed version falls within 2010 R3 through 2014 R1, or matches versions 2010, 2013, or 2014.
-
Inspect certificate signature algorithmsExamine the X.509 certificates configured for SSL/TLS communications in ClearSCADA. Use tools such as OpenSSL (openssl x509 -in <certificate.pem> -text -noout) or the Windows certificate snap-in to view the signature algorithm field for each certificate.Affected if Any certificate in use shows 'md5' or 'MD5' as the signature algorithm in the certificate details.
-
Check certificate store for MD5-signed certificatesReview all certificates stored in the ClearSCADA certificate store or Windows certificate store used by the application. Export or list certificates and filter for those using MD5 hashing.Affected if One or more certificates with MD5-based signatures are present in the certificate stores used by ClearSCADA.
-
Review certificate validation configurationExamine ClearSCADA configuration files and settings related to certificate validation. Look for any settings that explicitly allow or enforce MD5-based certificate verification.Affected if Configuration permits MD5-signed certificates or disables strong certificate validation.
A user is affected if their ClearSCADA version is 2010, 2013, or 2014 (specifically R3 through R1.1 range) and the system is using any certificates signed with the MD5 algorithm.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade ClearSCADA to a version that uses SHA-256 or stronger hashing for certificate validation. Replace all existing MD5-signed certificates with certificates using modern cryptographic algorithms and implement certificate pinning for critical communications.
