CVE-2006-6982: 3proxy

Medium severity, CVSS 5.0. EPSS: 1% chance of exploitation in the next 30 days.

3proxy 0.5 to 0.5.2 does not offer NTLM authentication before basic authentication, which might cause browsers with incomplete RFC2616/RFC2617 support to use basic cleartext authentication even if NTLM is available, which makes it easier for attackers to steal credentials.

Affected products

• 3proxy 3proxy: version 0.5 only; version 0.5.1 only; version 0.5.2 only
