Description

This security bulletin contains information about 5 vulnerabilities.


1) Cross-site scripting (CVE-ID: CVE-2017-9249)

Vulnerability allows a remote attacker to perform XSS attacks.

The vulnerability is caused by an input validation error in Allen Disk 1.6. A remote authenticated attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in victim's browser in security context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


2) Input validation error (CVE-ID: CVE-2017-9090)

The vulnerability allows a remote non-authenticated attacker to manipulate data.

reg.php in Allen Disk 1.6 doesn't check if isset($_SESSION['captcha']['code'])==1, which makes it possible to bypass the CAPTCHA via an empty $_POST['captcha'].


3) Input validation error (CVE-ID: CVE-2017-9091)

The vulnerability allows a remote non-authenticated attacker to manipulate data.

/admin/loginc.php in Allen Disk 1.6 doesn't check if isset($_SESSION['captcha']['code']) == 1, which leads to CAPTCHA bypass by emptying $_POST['captcha'].


4) Cross-site request forgery (CVE-ID: CVE-2017-8848)

The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to insufficient validation of the HTTP request origin. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.


5) Cross-site scripting (CVE-ID: CVE-2017-8832)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data in the id parameter to downfile. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
