Status: ModifiedMedium (5.5)—
On Phoenix Contact PLCnext Control Devices versions before 2021.0 LTS an attacker can use the knowledge gained by reading the insufficiently protected sensitive information to plan further attacks.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
- Base score: 5.5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.75%
- Percentile among all scored CVEs: 53
- Score date: 10/6/2026
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).
