CVE-2009-4157

Status: ModifiedMedium (4.3)—💥 Exploit

Multiple cross-site scripting (XSS) vulnerabilities in index.php in the ProofReader (com_proofreader) component 1.0 RC9 and earlier for Joomla! allow remote attackers to inject arbitrary web script or HTML via the URI, which is not properly handled in (1) 404 or (2) error pages.

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.
