Description

This security bulletin contains information about 3 vulnerabilities.


1) Stored cross-site scripting (CVE-ID: CVE-2020-11106)

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear


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 "dialog.php" page in $_SESSION['RF']["view_type"] . A remote attacker can permanently inject 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.


2) Input validation error (CVE-ID: CVE-2020-10567)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code on the system.

The vulnerability exists due to insufficient validation of user-supplied input in the "ajax_calls.php" file in the "save_img" action in the "name" parameter. A remote attacker can execute PHP code if a legitimate JPEG image contains this code in the EXIF data and the .php extension is used in the name parameter.


3) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2020-10212)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/E:U/U:Green


The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists in the "url" parameter due to the file-extension blocking is mishandled and it is possible for a DNS hostname to resolve to an internal IP address. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
