Base vector

AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions: YurunProxy version 0.01

Description: The issue is related to a Cross Site Scripting (XSS) vulnerability in the src/Client.php file. The exit function will terminate the script and print a message that includes values from the socket read. This could potentially allow an attacker to inject malicious scripts.

Recommendations: For YurunProxy version 0.01, consider disabling the exit function in src/Client.php until a patch is available to prevent the script from printing user-controlled input. Restrict access to the socket read values to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
