Description

This security bulletin contains information about 2 vulnerabilities.


1) Command Injection (CVE-ID: CVE-2025-8956)

CWE-ID: CWE-77 - Command 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 commands on the system.

The vulnerability exists due to insufficient input validation in the getenv function of the /htdocs/cgibin file in the ssdpcgi component. A remote user can pass specially crafted data to the application and execute arbitrary commands.


2) Cross-site scripting (CVE-ID: CVE-2025-9003)

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:L/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 /bsc_lan.php file of the DHCP Reserved Address Handler component. A remote user 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.
