CVE-2017-16884

Status: ModifiedMedium (6.1)—💥 Exploit

Cross-site scripting (XSS) vulnerability in MistServer before 2.13 allows remote attackers to inject arbitrary web script or HTML via vectors related to failed authentication requests alerts.

CVSS

Exploitation probability (EPSS)

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.
