Status: ModifiedMedium (6.3)—
Cisco IOS 15.1 and 15.2 and IOS XE 3.x, when configured as an IPsec hub with X.509 certificates in use, allows remote authenticated users to cause a denial of service (segmentation fault and device crash) via unspecified vectors, aka Bug ID CSCtq61128.
CVSS
- Version: 2.0
- Vector: AV:N/AC:M/Au:S/C:N/I:N/A:C
- Base score: 6.3
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.59%
- Percentile among all scored CVEs: 46
- Score date: 10/8/2026
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).
