CVE-2018-7810
Status: ModifiedMedium (6.1)—
An Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability exists in the embedded web servers in all Modicon M340, Premium, Quantum PLCs and BMXNOR0200 allowing an attacker to craft a URL containing JavaScript that will be executed within the user's browser, potentially impacting the machine the browser is running on.
CVSS
- Version: 3.0
- Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
- Base score: 6.1
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.90%
- Percentile among all scored CVEs: 58
- 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).
