ProjectSend Improper Authentication Vulnerability
ProjectSend · ProjectSend
ProjectSend (versions prior to r1720) contains an improper authentication flaw in its options.php endpoint, which governs the application's configuration. An unauthenticated remote attacker can exploit it by sending crafted HTTP requests to modify the application's settings, which can lead to creating accounts, uploading webshells, and embedding malicious JavaScript, with no user interaction or prior authentication required.
ProjectSend versions prior to r1720 are affected by an improper authentication vulnerability. Remote, unauthenticated attackers can exploit this flaw by sending crafted HTTP requests to options.php, enabling unauthorized modification of the application's configuration. Successful exploitation allows attackers to create accounts, upload webshells, and embed malicious JavaScript.
