CVE-2011-3207
Status: ModifiedMedium (5)—
crypto/x509/x509_vfy.c in OpenSSL 1.0.x before 1.0.0e does not initialize certain structure members, which makes it easier for remote attackers to bypass CRL validation by using a nextUpdate value corresponding to a time in the past.
CVSS
- Version: 2.0
- Vector: AV:N/AC:L/Au:N/C:N/I:P/A:N
- Base score: 5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 4.36%
- Percentile among all scored CVEs: 91
- Score date: 10/7/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
