1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-29268 Description: ALLNET ALL-RUT22GW v3.3.8 was discovered to store hardcoded credentials in the libicos.so library. CVSS Score: 9.8

Severity Evaluation: The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for unauthorized access to sensitive systems, which can lead to significant data breaches, system compromise, and operational disruptions.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Network Exploitation: An attacker with network access to the ALL-RUT22GW router can exploit the hardcoded credentials to gain unauthorized access.
2. Local Exploitation: An attacker with physical access to the device can extract the hardcoded credentials from the libicos.so library.
3. Supply Chain Attack: An attacker could compromise the supply chain to introduce malicious firmware updates that exploit the hardcoded credentials.

Exploitation Methods:

1. Credential Extraction: Attackers can reverse-engineer the libicos.so library to extract the hardcoded credentials.
2. Brute Force Attack: Knowing the existence of hardcoded credentials, attackers can attempt brute force attacks to guess the credentials.
3. Firmware Analysis: Attackers can analyze the firmware to identify and exploit the hardcoded credentials.

3. Affected Systems and Software Versions

Affected Systems:

• ALLNET ALL-RUT22GW routers running firmware version v3.3.8.

Software Versions:
