What is CVE-2023-54341?

Webgrind versions 1.1 and earlier are vulnerable to a reflected cross-site scripting (XSS) flaw, which enables unauthenticated attackers to inject malicious scripts via the 'file' parameter in index.php. This vulnerability arises from insufficient input encoding of user-controlled data, allowing attackers to execute arbitrary JavaScript in the browsers of unsuspecting users by crafting specific URLs. Proper validation and encoding practices are essential to mitigate such risks.

Affected Version(s)

Webgrind 1.1

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
