CVE-2017-6913

Status: ModifiedMedium (6.1)—💥 PoC

Cross-site scripting (XSS) vulnerability in the Open-Xchange webmail before 7.6.3-rev28 allows remote attackers to inject arbitrary web script or HTML via the event attribute in a time tag.

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.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
