Last modified

CVE-2012-10054 is a critical-severity vulnerability rated 9.3/10 on the CVSS scale. Umbraco CMS versions prior to 4.7.1 are vulnerable to unauthenticated remote code execution via the codeEditorSave.asmx SOAP endpoint, which exposes a SaveDLRScript operation that permits arbitrary file uploads without authentication. By exploiting a path traversal flaw in the fileName parameter, attackers can write malicious ASPX scripts directly into the web-accessible /umbraco/ directory and execute them remotely.. EPSS estimates a 2.64% chance of exploitation in the next 30 days.
