curl before 7.53.0 has an incorrect TLS Certificate Status Request extension feature that asks for a fresh proof of the server's certificate's validity in the code that checks for a test success or failure. It ends up always thinking there's valid proof, even when there is none or if the server doesn't support the TLS extension in question. This could lead to users not detecting when a server's certificate goes invalid or otherwise be mislead that the server is in a better shape than it is in reality. This flaw also exists in the command line tool (--cert-status).

Security readout for executives and security teams

CVE-2017-2629 is a curl certificate-status checking flaw. When users asked curl to verify fresh proof that a server certificate was still valid, curl could incorrectly treat missing proof as valid. This can mislead teams about certificate health, but the reported impact is limited. Exposure is most relevant where curl before 7.53.0 is used and teams rely on certificate status checking for trust decisions. The source bundle does not establish broader product impact beyond curl. Treat as a targeted maintenance item, not an emergency. Prioritize systems where curl certificate-status validation informs security, compliance, or operational trust decisions. Mitigation focus: Upgrade curl to 7.53.0 or a vendor-supported fixed package.; Review operating system and distribution advisories for backported fixes.; Do not rely solely on affected certificate-status results until fixed..

Improper Certificate Validation

Improper Certificate Validation represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
