Description

This security bulletin contains information about 4 vulnerabilities.

1) Privilege escalation (CVE-ID: CVE-2018-2381)

CWE-ID: CWE-862 - Missing Authorization

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

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The vulnerability exists due to the failure to perform necessary authorization checks for an authenticated user. A local attacker can gain unauthorized access and obtain sensitive information.

2) Cross-site scripting (CVE-ID: CVE-2018-2364)

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:A/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. 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.

3) Server-side request forgery (CVE-ID: CVE-2018-2370)

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:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote user to perform SSRF-attack on the target system.

The weakness exists due to insufficient validation of user-supplied input. A remote attacker can use common techniques to determine which ports are in use on the backend server and perform server-sire request forgery attack.

4) Cross-site scripting (CVE-ID: CVE-2018-2371)
