In today's post, we will be discussing a recently discovered vulnerability - CVE-2023-41260, which affects Best Practical Request Tracker (RT) versions before 4.4.7 and 5.x before 5..5. This vulnerability allows cybercriminals to potentially gain unauthorized access to sensitive information via the software’s mail-gateway REST API.
Request Tracker (RT), developed by Best Practical Solutions, is an open-source ticketing and task management system that is widely used for handling issues related to bug tracking, software development, and customer support. In this post, we will delve into the details of the vulnerability, including information on the exploit, code snippets, and links to original references.
Exploit Details
CVE-2023-41260 is a result of an information exposure vulnerability present in the response of mail-gateway REST API calls within the Best Practical Request Tracker. Cybercriminals can exploit this vulnerability by sending specially crafted requests to the affected application's mail-gateway REST API, possibly achieving unauthorized access to sensitive data such as private tickets and user data.
This vulnerability exists mainly due to insufficient filtering of user input and improper access control when processing mail-gateway REST API requests.
Below is a code snippet that demonstrates the vulnerability in affected versions of Request Tracker
sub ProcessRequest {
my $self = shift;
my ($user, $pass) = $self->GetAuthentication();
my ($status, $msg) = $self->MailGateway(
Queue => $queue,
Action => $action,
Ticket => $ticket_id,
Message => $message,
Subject => $subject,
From => $from,
To => $to,
Cc => $cc,
Username => $user,
Password => $pass,
...
);
...
}
In this example, the $user and $pass variables, which represent the username and password of the Request Tracker instance, are not adequately sanitized or validated before being passed to the MailGateway function, making it possible for an attacker to inject malicious payloads or manipulate the request.
