CVE-2014-7997
Status: ModifiedMedium (6.1)—
The DHCP implementation in Cisco IOS on Aironet access points does not properly handle error conditions with short leases and unsuccessful lease-renewal attempts, which allows remote attackers to cause a denial of service (device restart) by triggering a transition into a recovery state that was intended to involve a network-interface restart but actually involves a full device restart, aka Bug ID CSCtn16281.
CVSS
- Version: 2.0
- Vector: AV:A/AC:L/Au:N/C:N/I:N/A:C
- Base score: 6.1
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.69%
- Percentile among all scored CVEs: 52
- Score date: 10/19/2026
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).
