CVE-2017-3732

27

FAUCET Score

CVE-2017-3732 is a carry propagating bug in the x86_64 Montgomery squaring procedure affecting OpenSSL versions 1.0.2 before 1.0.2k and 1.1.0 before 1.1.0d, as well as associated Node.js products. This medium-severity vulnerability (CVSS 5.9) has a high impact on confidentiality, particularly for DH key deduction, but requires significant resources and specific online access to an unpatched system. While RSA and DSA attacks are highly unlikely, DH attacks are considered just feasible. There is no evidence of active exploitation, no public exploit code (Metasploit, Nuclei, ExploitDB), and it is not listed in the KEV catalog or Hot List, despite receiving moderate community discussion and media coverage.
