Description

This security bulletin contains information about 4 vulnerabilities.


1) Relative path traversal (CVE-ID: CVE-2017-13996)

CWE-ID: CWE-23 - Relative Path Traversal

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


The vulnerability allows a remote attacker to gain access to important data on the target system.

The weakness exists due to improper protection of critical files by the user interface. A remote attacker can create or modify files or possibly execute arbitrary code.

2) Insufficient entropy (CVE-ID: CVE-2017-13992)

CWE-ID: CWE-331 - Insufficient Entropy

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.

The weakness exists due to insufficient utilization of random number generation for the web interface authentication mechanism. A remote attacker can gain unauthorized access to the system and execute arbitrary code.

3) Cross-site scripting (CVE-ID: CVE-2017-13994)

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.


4) Information disclosure (CVE-ID: CVE-2017-13998)

CWE-ID: CWE-522 - Insufficiently Protected Credentials

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


The vulnerability allows a remote attacker to gain access to obtain potentially sensitive information.

The weakness exists due to insufficient protection of sensitive information from unauthorized access. A remote attacker can gain access to user's credentials.
