CVE-2018-7958
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 · uneditedThere is an anonymous TLS cipher suites supported vulnerability in Huawei eSpace product. An unauthenticated, remote attacker launches man-in-the-middle attack to hijack the connection from a client when the user signs up to log in by TLS. Due to insufficient authentication, which may be exploited to intercept and tamper with the data information.
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 confidenceHuawei eSpace supports anonymous TLS cipher suites that do not authenticate the server, allowing an unauthenticated remote attacker to perform man-in-the-middle attacks during user login/signup and intercept or tamper with data traffic.

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 the product modelAccess the device management interface or check the system information to confirm the product is Huawei eSpace 7950Affected if The product is not Huawei eSpace 7950, then this CVE does not apply
-
Check the firmware versionNavigate to the device settings or use the command line interface to retrieve the firmware version. Compare it to v200r003c30Affected if The installed version is exactly v200r003c30, the device is affected
-
Verify TLS is enabledExamine the TLS/SSL configuration settings in the device management console or configuration files to determine if TLS is activeAffected if TLS is not enabled, the vulnerability cannot be exploited
-
Inspect TLS cipher suite configurationReview the TLS configuration for the presence of anonymous cipher suites such as ADH (Anonymous Diffie-Hellman), AECDH (Anonymous Elliptic Curve Diffie-Hellman), or any cipher suites ending in a or anonymous in the nameAffected if Anonymous TLS cipher suites are listed or enabled in the configuration, the device is vulnerable to MITM attacks
A user is affected only if they have Huawei eSpace 7950 firmware version v200r003c30 with TLS enabled and anonymous cipher suites configured.

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 dataDisable anonymous TLS cipher suites (e.g., ADH, AECDH, DH/ECDHE with anonymous key exchange) in the TLS configuration and enable only authenticated cipher suites with strong encryption.
