VAR-200604-0488

Vulnerability from variot - Updated: 2025-04-03 19:48

na-img-4.0.34.bin for the IP3 Networks NetAccess NA75 has a default username of admin and a default password of admin. IP3 Networks NetAccess NA75 devices are susceptible to multiple local vulnerabilities: - A command-injection vulnerability due to insufficient input-sanitization of user-supplied commands. This issue allows attackers to execute arbitrary shell commands in the underlying UNIX-based operating system. - An encrypted-password information-disclosure vulnerability. This issue may aid attackers in brute-force password-guessing attacks. - An insecure default-permissions vulnerability. This issue allows attackers to access or corrupt potentially sensitive information. These issues are present in version 4.0.34 of the device's firmware; other versions may also be affected.

TITLE: IP3 Networks NA75 SQL Injection Vulnerability and Weaknesses

SECUNIA ADVISORY ID: SA19818

VERIFY ADVISORY: http://secunia.com/advisories/19818/

CRITICAL: Less critical

IMPACT: Security Bypass, Manipulation of data, Exposure of sensitive information, Privilege escalation

WHERE:

From local network

OPERATING SYSTEM: IP3 Networks NA75 http://secunia.com/product/9602/

DESCRIPTION: Ralph Moonen has reported a vulnerability and some weaknesses in IP3 Networks NA75, which can be exploited by malicious, local users to potentially gain escalated privileges and disclose or manipulate sensitive information, or by malicious people to conduct SQL injection attacks.

1) Some input passed in the web interface is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Example: * The password field during login.

2) Some input validation errors in the command line interface can be exploited to inject arbitrary shell commands via the "`" backtick character.

3) The shadow password file has world-readable permissions, which can be exploited to disclose other users' encrypted passwords.

4) The database file is stored with world-readable and world-writable permissions.

SOLUTION: Apply patch available from the vendor. http://www.ip3.com/supportoverview.htm
