Vulnerability Disclosure Timeline: ================================== 2015-03-21: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Exploitation Technique: ======================= Remote Severity Level: =============== Low Technical Details & Description: ================================ A cross site request forgery web vulnerability has been discovered in the official DirectAdmin CP v1.50.0 control panel web-application. The vulnerability allows remote attacker to prepare client-side websites with malicious codes to execute internal application functions via non-expired user session credentials. DirectAdmin suffers from cross site request forgery web vulnerability that is located in the CMC_FILE_MANAGER module POST method request. Remote attackers are able to prepare malicious websites that can execute client-side application functions to add/edit via non-expired session. The attack vector of the issue is client-side and the request method to inject is POST. The attacker preapres a malicious website wiht a hidden POST method request to execute in the CMD_FILE_MANAGER the edit/add function with already defined perimeters. The security risk of the client-side web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 3.0. Exploitation of the non-persistent web vulnerability requires no privileged web application user account and low or medium user interaction. Successful exploitation of the vulnerability results in session hijacking, non-persistent phishing, non-persistent external redirects, non-persistent load of malicious script codes or non-persistent web module context manipulation. Request Method(s): [+] POST Vulnerable Module(s): [+] CMD_FILE_MANAGER Vulnerable Function(s): [+] Edit Proof of Concept (PoC): ======================= The cross site request forgery vulnerability can be exploited by remote attackers without privileged application user account and with low or medium user interaction. For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue. PoC: Create New File and Edit a file (CMD_FILE_MANAGER)
Security Risk: ============== The security risk of the client-side cross site request forgery web vulnerability in the web-application is estimated as medium.
