CVE-2025-27797

Comprehensive Technical Analysis of CVE-2025-27797

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-27797 Description: This vulnerability involves an OS command injection flaw in the Wi-Fi AP UNIT 'AC-WPS-11ac series'. If exploited, it allows a remote attacker to execute arbitrary OS commands, provided they can log in to the product. CVSS Score: 9.8

Severity Evaluation:

• Criticality: The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for complete system compromise and the ability to execute arbitrary commands remotely.
• Impact: Successful exploitation can lead to unauthorized access, data breaches, and potential takeover of the affected device, which can be used as a pivot point for further attacks within the network.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: An attacker can exploit this vulnerability remotely by logging into the device. This could be achieved through brute-forcing login credentials or exploiting weak/default passwords.
• Phishing: Attackers may use phishing techniques to trick users into revealing their login credentials.
• Network Scanning: Attackers can scan the network for vulnerable devices and attempt to exploit them.

Exploitation Methods:

• Command Injection: Once logged in, the attacker can inject malicious commands into the system, leading to unauthorized actions such as data exfiltration, system configuration changes, or installation of malware.
• Privilege Escalation: If the attacker gains access with elevated privileges, they can perform more damaging actions, including modifying system files or disabling security features.
