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 · unedited
High-risk TrustAllCerts routines disable standard TLS certificate validation. Combined with hard-coded DES symmetric encryption keys, a Man-in-the-Middle (MITM) actor could decrypt network traffic.

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 confidence

The TrustAllCerts implementation bypasses standard TLS certificate validation, allowing any certificate to be accepted. Combined with hard-coded DES symmetric encryption keys embedded in the code, an attacker performing a man-in-the-middle (MITM) attack can intercept and decrypt sensitive network traffic.

MitigationReplace TrustAllCerts with proper certificate chain validation using trusted CA stores, and replace hardcoded DES keys with dynamically generated keys using secure key management.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify firmware version
    Access the device administration interface or check system files to retrieve the current firmware version string (often found in Settings > About, or via SSH/Telnet checking /etc/version or similar), then compare it to the affected range: versions <= m6e_ai_1.00.000019
    Affected if Firmware version is m6e_ai_1.00.000019 or earlier
  2. Search for TrustAllCerts code patterns
    If you have access to the firmware image or can run commands on the device, search source code or binary strings for patterns like 'TrustAllCerts', 'TrustAll', 'validateCertificate=false', or similar certificate validation bypass implementations
    Affected if Code or binaries contain routines that disable TLS certificate validation
  3. Search for hardcoded DES keys
    If you have access to the firmware image or device shell, search configuration files, binary strings, or code repositories for hardcoded cryptographic keys, particularly DES (Data Encryption Standard) keys, looking for fixed or embedded key values
    Affected if Hardcoded DES keys are present in firmware, configuration, or code
  4. Inspect TLS/SSL configuration
    Examine network client configurations, SSLContext settings, or HTTP client initialization code to verify whether certificate validation is properly enabled or intentionally disabled
    Affected if Certificate validation is disabled or set to accept all certificates unconditionally
  5. Detect DES encryption in network traffic
    Use a network capture tool (such as tcpdump or Wireshark) to intercept and analyze traffic from the device, looking for DES-encrypted payloads or protocol signatures indicating weak symmetric encryption is in use
    Affected if Network communications are encrypted using DES rather than modern strong ciphers

A user is affected if their Acer Connect M6e 5g firmware is version m6e_ai_1.00.000019 or lower and contains the TrustAllCerts bypass with hardcoded DES keys.
