Cohesity TranZman Migration Appliance Release 4.0 Build 14614 was discovered to use a weak cryptography algorithm for data encryption, allowing attackers to trivially reverse the encyption and expose credentials.
Security readout for executives and security teams
Plain-English summary
This issue could expose credentials handled by a Cohesity TranZman Migration Appliance because encryption is described as weak and reversible. The business risk is credential disclosure, especially during migration work, rather than service outage.
Executive priority
Prioritize within normal vulnerability management, with faster action if the appliance handled privileged, backup, cloud, or migration credentials. The main urgency is preventing credential reuse after possible exposure.
Technical view
CVE-2025-63912 is a CWE-327 weak-cryptography issue in Cohesity TranZman Migration Appliance Release 4.0 Build 14614. CVSS 3.1 is 5.5 with local access and low privileges required, no user interaction, and high confidentiality impact only.
Likely exposure
Exposure appears limited to environments using Cohesity TranZman Migration Appliance Release 4.0 Build 14614. The CVE record’s affected vendor and product metadata is incomplete, so confirm deployments by asset inventory and appliance build data.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation evidence. The CVSS vector indicates an attacker needs local access and low privileges, reducing broad internet risk but making insider or compromised-account scenarios relevant.
Researcher notes
Evidence is limited to the CVE description, CVSS vector, CWE-327 classification, and researcher references. The bundle does not provide vendor-confirmed affected CPEs, patch versions, exploit-in-the-wild claims, or detailed remediation steps.
Mitigation direction
Identify any TranZman Migration Appliance instances and confirm their build numbers.
Restrict local and administrative access to migration appliances immediately.
Rotate credentials stored, processed, or encrypted by affected appliances.
Check Cohesity or project guidance for fixed builds or supported remediation.
Retire or isolate affected appliances if no vendor fix is available.
Validation and detection
Confirm whether Release 4.0 Build 14614 exists in the environment.
Review appliance access records for unexpected local or privileged account activity.
Inventory credentials handled by the migration appliance during its lifecycle.
Verify credential rotation completed for accounts exposed to the appliance.
Track vendor guidance because no patch detail is provided in the bundle.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
