LittleSis – Cross-Site Scripting (XSS) #25

Closed bestshow closed 7 years ago

bestshow commented 7 years ago

Product: LittleSis Download: https://github.com/littlesis-org/littlesis Vunlerable Version: latest version Tested Version: latest version Author: ADLab of Venustech

Advisory Details: A Cross-Site Scripting (XSS) was discovered in“LittleSis latest version”, which can be exploited to execute arbitrary code. The vulnerability exists due to insufficient filtration of user-supplied data in the “log” HTTP GET parameter passed to the “littlesis-master/web/yshout/history/index.php” URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website. The exploitation example below uses the "alert()" JavaScript function to see a pop-up messagebox: Poc: http://localhost/.../littlesis-master/web/yshout/history/index.php?log=%27test%27})%3C/script%3E%3Cscript%3Ealert(1);%3C/script%3E%3Cscript%3E

Excuse me, is there anyone dealing with this issue?
