CVE-2025-52689

Comprehensive Technical Analysis of CVE-2025-52689

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-52689 CVSS Score: 9.8

The CVSS score of 9.8 indicates that this vulnerability is critical. The high score is likely due to the potential for unauthenticated attackers to gain administrative privileges, which can lead to significant impacts on confidentiality, integrity, and availability.

Key Factors Contributing to Severity:

• Unauthenticated Access: The attacker does not need any prior credentials.
• Administrative Privileges: Successful exploitation grants the attacker high-level access.
• Session ID Spoofing: The vulnerability involves spoofing login requests to obtain valid session IDs.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: The attacker can exploit the vulnerability over the network, making it accessible remotely.
• Man-in-the-Middle (MitM) Attacks: Intercepting and modifying login requests to spoof session IDs.
• Phishing and Social Engineering: Tricking users into initiating login requests that can be intercepted and manipulated.

Exploitation Methods:

• Session ID Spoofing: Crafting malicious login requests that bypass authentication mechanisms.
• Replay Attacks: Capturing valid login requests and replaying them to gain unauthorized access.
• Automated Scripts: Using scripts to automate the process of spoofing login requests and obtaining session IDs.

3. Affected Systems and Software Versions

Based on the references provided, the vulnerability likely affects:

• OmniAccess Stellar Access Points: Specific versions and models of these access points are vulnerable.
• Firmware Versions: Certain firmware versions of the OmniAccess Stellar Access Points are affected.
