Description
This security bulletin contains information about 5 vulnerabilities.
1) Observable Response Discrepancy (CVE-ID: CVE-2023-32346)
CWE-ID: CWE-204 - Observable Response Discrepancy
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:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the observable response discrepancy issue. A remote attacker can create a list of the serial numbers and MAC addresses of all devices cloud-connected to the Remote Management System.
2) Improper Authentication (CVE-ID: CVE-2023-32347)
CWE-ID: CWE-287 - Improper Authentication
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 an error in when processing authentication requests. A remote attacker can obtain the serial number and MAC address of the device, bypass authentication process and gain unauthorized access to the application.
3) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2023-32348)
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 due to insufficient validation of user-supplied input in the virtual private network (VPN) hub feature. 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.
4) Cross-site scripting (CVE-ID: CVE-2023-2587)
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 in the main page of the web interface. 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.
5) Input validation error (CVE-ID: CVE-2023-2588)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/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 inclusion of web functionality from an untrusted source. A remote attacker can use a specially crafted webpage that uses a trusted and certified domain to execute arbitrary code on the target system.
