Cisco AS5350 IOS 12.2(11)T with access control lists (ACLs) applied and possibly with ssh running allows remote attackers to cause a denial of service (crash) via a port scan, possibly due to an ssh bug. NOTE: this issue could not be reproduced by the vendor

CVSS

Base score: 7.8
Version: 2.0
Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 5.86 %
Percentile among all scored CVEs: 93
Score date: 10/20/2026

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).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
