What is CVE-2013-10038?

FlashChat versions 6.0.2 through 6.0.8 contain a serious vulnerability in the upload.php endpoint, which allows an attacker to upload arbitrary files without authentication. This occurs due to inadequate validation of file types, enabling the execution of malicious PHP scripts on the server once uploaded. The potential for remote code execution poses severe risks, allowing attackers to manipulate the server environment as the web server user. Organizations should ensure immediate patching and implement robust security measures to mitigate the risk of exploitation.

Affected Version(s)

FlashChat 6.0.2

FlashChat 6.0.4 <= 6.0.8

Exploit Proof of Concept (PoC)
