CVE-2017-1000007
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 · uneditedtxAWS (all current versions) fail to perform complete certificate verification resulting in vulnerability to MitM attacks and information disclosure.
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 confidenceThe txAWS library (all current versions) fails to perform complete SSL/TLS certificate verification, allowing Man-in-the-Middle attackers to intercept encrypted communications and disclose sensitive data by impersonating legitimate servers.

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.
-
Check if txaws library is installedRun 'pip list' or check your Python environment for 'txaws' or 'txaws' packageAffected if txaws is present in the Python environment and used for AWS connections
-
Identify the txaws versionRun 'pip show txaws' or check the installed package metadata for version informationAffected if Any version of txaws is installed (all versions are affected)
-
Check for SSL verification code in txawsInspect the txaws source code, specifically looking for httplib or urllib calls with SSL context settings, or verify if ssl.create_default_context() or ssl.wrap_socket() is used with verify=False or no certificate validationAffected if The code shows ssl verification is disabled or incomplete (no hostname verification, no chain validation, or no expiration checking)
-
Verify if applications use txaws for AWS connectionsSearch project code for imports like 'from txaws import' or 'import txaws' and review how AWS service clients are instantiatedAffected if Applications import and use txaws to connect to AWS services over HTTPS
If txaws is installed and used to make HTTPS connections to AWS services, the environment is affected by incomplete SSL/TLS certificate verification.
Generated from the published advisory. Verify against your own configuration.
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 dataUpdate or patch txAWS to a version that implements proper certificate chain validation, hostname verification, and certificate expiration checking. Alternatively, migrate to a secure AWS SDK implementation.
