CVE-2003-0047: n/a vulnerability

CVE-2003-0047: SSH2 clients for VanDyke (1) SecureCRT 4.0.2 and 3.4.7, (2) SecureFX 2.1.2 and 2.0.4, and (3) Entunnel 1.0....

SSH2 clients for VanDyke (1) SecureCRT 4.0.2 and 3.4.7, (2) SecureFX 2.1.2 and 2.0.4, and (3) Entunnel 1.0.2 and earlier, do not clear logon credentials from memory, including plaintext passwords, which could allow attackers with access to memory to steal the SSH credentials.

Security readout for executives and security teams

This old VanDyke SSH client issue can leave users' SSH passwords in process memory after login. An attacker who can read that memory could recover credentials and use them elsewhere. It matters mainly where legacy SecureCRT, SecureFX, or Entunnel versions still run on managed workstations, jump hosts, or terminal servers. Exposure is most likely in legacy environments still using the named VanDyke client versions, especially on shared administration hosts. Systems not running these specific old clients are not shown as affected by the provided sources. Treat this as a legacy credential exposure risk, not a modern internet-facing emergency. Prioritize remediation where affected clients exist on privileged administration systems or where password reuse could enable broader compromise. Mitigation focus: Inventory endpoints for the named VanDyke products and versions.; Check VanDyke guidance for supported fixed releases or upgrade paths.; Retire or replace unsupported legacy SSH client installations..
