CVE-2020-15183

Estado: ModificadaMedia (4.8)—

SoyCMS 3.0.2 and earlier is affected by Reflected Cross-Site Scripting (XSS) which leads to Remote Code Execution (RCE) from a known vulnerability. This allows remote attackers to force the administrator to edit files once the adminsitrator loads a specially crafted webpage.

CVSS
