CVE-2023-33480

Estado: ModificadaAlta (8.8)—

RemoteClinic 2.0 contains a critical vulnerability chain that can be exploited by a remote attacker with low-privileged user credentials to create admin users, escalate privileges, and execute arbitrary code on the target system via a PHP shell. The vulnerabilities are caused by a lack of input validation and access control in the staff/register.php endpoint and the edit-my-profile.php page. By sending a series of specially crafted requests to the RemoteClinic application, an attacker can create admin users with more privileges than their own, upload a PHP file containing arbitrary code, and execute arbitrary commands via the PHP shell.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
