CVE-2026-32650
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 · uneditedAnviz CrossChex Standard is vulnerable when an attacker manipulates the TDS7 PreLogin to disable encryption, causing database credentials to be sent in plaintext and enabling unauthorized database access.
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 · moderate confidenceAnviz CrossChex Standard has a vulnerability where attackers can manipulate the TDS7 PreLogin negotiation packet to force encryption to be disabled. This causes database authentication credentials to be transmitted in plaintext, allowing attackers to intercept credentials and gain unauthorized access to the connected database.

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.
-
Confirm CrossChex Standard installationCheck for the Anviz CrossChex Standard application in your system programs or installation directory. Look for the executable (typically named CrossChex.exe or similar) in the program's installation folder.Affected if The application is present on the system, as all versions are affected by this vulnerability.
-
Identify database connectivity configurationLocate the database configuration file or settings panel within CrossChex Standard. This is typically found in the application settings, configuration files within the installation directory, or in the system registry where the application stores its database connection strings.Affected if CrossChex Standard is configured to connect to any database (SQL Server or similar using TDS protocol), making it vulnerable to TDS7 PreLogin negotiation manipulation.
-
Inspect TDS PreLogin negotiation trafficUse a network packet capture tool (such as Wireshark) to capture traffic on the port used by the database (typically port 1433 for SQL Server). Analyze the TDS7 PreLogin packet to determine if the encryption option is being set to OFF or can be manipulated by an attacker.Affected if The TDS PreLogin response shows encryption is disabled or set to not required, meaning credentials could be transmitted in plaintext.
-
Verify encryption settings in database connectionReview the CrossChex database connection settings or configuration files for any encryption-related parameters. Check if 'Encrypt' or 'TrustServerCertificate' settings are properly configured.Affected if Encryption is not explicitly enforced in the connection settings, leaving the connection vulnerable to encryption downgrade.
If Anviz CrossChex Standard is installed and connected to a database without enforced encryption in the TDS7 PreLogin negotiation, the system is affected and credentials may be transmitted in plaintext.

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 dataOrganizations should implement network segmentation to limit exposure of database traffic, deploy TLS/SSL inspection at the network perimeter to detect encryption downgrade attempts, and contact Anviz for an official patch that enforces encryption during TDS7 PreLogin negotiation.
