Vulnerability Disclosure Timeline: ================================== 2020-05-07: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Exploitation Technique: ======================= Remote Severity Level: =============== Medium Authentication Type: ==================== Pre auth - no privileges User Interaction: ================= Low User Interaction Disclosure Type: ================ Independent Security Research Technical Details & Description: ================================ A non-persistent cross site scripting vulnerability has been discovered in the official Tiny MySQL console 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 vulnerabilities are located in the `table` parameter of the `tinymy.php` file. The request method to inject the malicious script code is GET and the attack vector of the vulnerability is non-persistent on client-side. 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 application modules. Request Method(s): [+] GET Vulnerable Parameter(s): [+] table Proof of Concept (PoC): ======================= The non-persistent web vulnerability can be exploited by remote attackers without user account with low user interaction. For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue.
