Description: Some vulnerabilities were reported in yappa-ng. A remote user can execute arbitrary code on the target system. A remote user can also conduct cross-site scripting attacks.
A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site
running the yappa-ng software and will run in the security context of that site. As a result, the code will be able to access the
target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the
target user via web form to the site, or take actions on the site acting as the target user.
A remote user can also cause the
target system to include and execute arbitrary PHP code.
The vendor credits James Bercegay of the GulfTech Security Research
Team with reporting this flaw.
