CVE-2013-4881

Status: ModifiedMedium (6.8)—💥 Exploit

Cross-site request forgery (CSRF) vulnerability in core/admin/modules/users/create.php in BigTree CMS 4.0 RC2 and earlier allows remote attackers to hijack the authentication of administrators for requests that create an administrative user via an add user action to index.php.

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.
