Last modified Jun 16, 2026

CVE-2010-2450 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The keygen.sh script in Shibboleth SP 2.0 (located in /usr/local/etc/shibboleth by default) uses OpenSSL to create a DES private key which is placed in sp-key.pm. It relies on the root umask (default 22) instead of chmoding the resulting file itself, so the generated private key is world readable by default.. EPSS estimates a 1.23% chance of exploitation in the next 30 days.
