CVE-2006-6982: 3proxy 0.5 to 0.5.2 does not offer NTLM authentication before basic authentication, which might cause brows...

Security readout for executives and security teams

Older 3proxy releases may cause some browsers to send proxy credentials using Basic authentication instead of NTLM. Basic authentication can expose credentials in cleartext on unprotected connections, increasing credential theft risk where affected versions are still deployed. Exposure is likely limited to legacy 3proxy 0.5, 0.5.1, or 0.5.2 deployments using proxy authentication, especially where clients can send credentials over unencrypted network paths. Treat this as a legacy credential-protection issue. It is not flagged as actively exploited, but affected internet-facing or shared-network proxy deployments could expose reusable credentials and should be identified and retired or upgraded. Mitigation focus: Inventory 3proxy instances and confirm exact versions in use.; Review 3proxy vendor changelog and guidance for fixed releases.; Upgrade or replace affected 0.5 through 0.5.2 deployments if vendor guidance supports it..
