Description

This security bulletin contains information about 5 vulnerabilities.


1) Small Space of Random Values (CVE-ID: CVE-2023-39979)

CWE-ID: CWE-334 - Small Space of Random Values

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 bypass authentication process.

The vulnerability exists due to small space of random values. A remote attacker can bypass authentication process and gain unauthorized access to the application.


2) SQL injection (CVE-ID: CVE-2023-39980)

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

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


The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote user can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.


3) Improper Authentication (CVE-ID: CVE-2023-39981)

CWE-ID: CWE-287 - Improper Authentication

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:Green


The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in when processing authentication requests. A remote attacker can bypass authentication process and gain access to disclose device information.


4) Use of hard-coded credentials (CVE-ID: CVE-2023-39982)

CWE-ID: CWE-798 - Use of Hard-coded 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:Green


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

The vulnerability exists due to presence of hard-coded credentials in application code. A remote unauthenticated attacker can perform a man-in-the-middle (MitM) attack and enable the decryption of SSH traffic.


5) Improperly Controlled Modification of Dynamically-Determined Object Attributes (CVE-ID: CVE-2023-39983)

CWE-ID: CWE-915 - Improperly Controlled Modification of Dynamically-Determined Object Attributes

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


The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improperly controlled modification of dynamically-determined object attributes. A remote attacker can register/add a device via the nsm-web application.
