(Copy of the Homepage: http://project-open.net/ ) Abstract Advisory Information: ============================== The vulnerability laboratory core research team discovered multiple web vulnerabilities in the official Project Open v5.0.3 CMS. Affected Product(s): ==================== Project-Open Product: Project Open v5.0.3 - CMS (Web-Application) Vulnerability Disclosure Timeline: ================================== 2020-04-27: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Exploitation Technique: ======================= Remote Severity Level: =============== High Authentication Type: ==================== Restricted authentication (user/moderator) - User privileges User Interaction: ================= No User Interaction Disclosure Type: ================ Independent Security Research Technical Details & Description: ================================ 1.1 Multiple remote sql-injection web vulnerabilities has been discovered in the official Project Open v5.0.3 CMS web-application. The vulnerability allows remote attackers to inject or execute own sql commands to compromise the dbms or file system of the application. The sql injection vulnerabilities are located in the `order_by`, `forum_order_by` and `audit_id` parameters of the `./intranet-expenses/index` and `./intranet-audit/view` modules. The request method to inject or execute commands is GET and the attack vector is located on the application-side. Attackers with privileged accounts to edit are able to inject own sql queries via order or id parameter to compromise the dbms. Multiple unhandled and broken sql queries are visible as default debug to output for different roles as well. Exploitation of the remote sql injection vulnerability requires no user interaction and a privileged web-application user account. Successful exploitation of the remote sql injection results in database management system, web-server and web-application compromise. Request Method(s): [+] GET Vulnerable Module(s): [+] ./intranet-expenses/index [+] ./intranet-audit/view Vulnerable Parameter(s): [+] forum_order_by [+] order_by [+] audit_id 1.2 Multiple non-persistent cross site scripting vulnerabilities has been discovered in the official Project Open v5.0.3 CMS web-application. The vulnerability allows remote attackers to inject own malicious script codes with non-persistent attack vector to compromise browser to web-application requests from the client-side. The cross site scripting web security vulnerabilities are located in the `bread_crum_path` and `re_path` parameters of the `./intranet/projects/view` and `./intranet-filestorage` modules. The request method to inject the malicious script code is GET and the attack vector of the vulnerability is non-persistent on client-side. Remote attackers are able to inject own script codes to the client-side requested vulnerable web-application parameters. The attack vector of the vulnerability is non-persistent and the request method to inject/execute is GET. The vulnerabilities are classic client-side cross site scripting vulnerabilities. Successful exploitation of the vulnerability results in session hijacking, non-persistent phishing attacks, non-persistent external redirects to malicious source and non-persistent manipulation of affected or connected application modules. Request Method(s): [+] GET Vulnerable Module(s): [+] ./intranet/projects/view [+] ./intranet-filestorage Vulnerable Parameter(s): [+] bread_crum_path [+] rel_path Proof of Concept (PoC): ======================= 1.1 The remote sql-injection web vulnerabilities can be exploited by authenticated privileged user accounts without user interaction.
