CVE-2013-7307

Status: ModifiedMedium (5.4)—

The OSPF implementation on the Brocade Vyatta vRouter with software before 6.6R1 does not consider the possibility of duplicate Link State ID values in Link State Advertisement (LSA) packets before performing operations on the LSA database, which allows remote attackers to cause a denial of service (routing disruption) or obtain sensitive packet information via a crafted LSA packet, a related issue to CVE-2013-0149.

CVSS

Version: 2.0
Vector: AV:A/AC:M/Au:N/C:P/I:P/A:P
Base score: 5.4

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.95%
Percentile among all scored CVEs: 60
Score date: 10/4/2026

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).
