CWE-310Published: September 8, 2009· Updated: Jun 16, 2026
7.5
CVSS v3.1
Official Description
KDE KSSL in kdelibs 3.5.4, 4.2.4, and 4.3 does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
Technical Analysis
CVE-2009-2702 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
