Last modified Jun 17, 2026

CVE-2016-3125 is a vulnerability of currently unknown severity. The mod_tls module in ProFTPD before 1.3.5b and 1.3.6 before 1.3.6rc2 does not properly handle the TLSDHParamFile directive, which might cause a weaker than intended Diffie-Hellman (DH) key to be used and consequently allow attackers to have unspecified impact via unknown vectors.. EPSS estimates a 6.98% chance of exploitation in the next 30 days.
