Comprehensive Technical Analysis of EUVD-2026-11079

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in the web-based management interface of AOS-CX switches is critical. The CVSS (Common Vulnerability Scoring System) base score of 9.8 indicates a high severity level. The vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H breaks down as follows:

• Attack Vector (AV): Network (N) - The vulnerability can be exploited remotely over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources to exploit.
• Privileges Required (PR): None (N) - No prior authentication is needed to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required for the attack to succeed.
• Scope (S): Unchanged (U) - The vulnerability does not change the security scope.
• Confidentiality (C): High (H) - The vulnerability allows for significant breaches of confidentiality.
• Integrity (I): High (H) - The vulnerability allows for significant breaches of integrity.
• Availability (A): High (H) - The vulnerability allows for significant breaches of availability.

Given these metrics, the vulnerability poses a severe risk to the confidentiality, integrity, and availability of the affected systems.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector is through the web-based management interface of the AOS-CX switches. An unauthenticated remote actor could exploit this vulnerability by:

• Bypassing Authentication Controls: The actor could circumvent existing authentication mechanisms, potentially allowing them to reset the admin password.
• Network Scanning: The actor could scan for vulnerable AOS-CX switches on the network and attempt to exploit the vulnerability.
• Phishing and Social Engineering: Combining this vulnerability with social engineering tactics could increase the likelihood of a successful attack.

3. Affected Systems and Software Versions

The vulnerability affects the following versions of AOS-CX switches:

• 10.13.0000 ≤ 10.13.1101
• 10.16.0000 ≤ 10.16.1020
• 10.17.0000 ≤ 10.17.0001
• 10.10.0000 ≤ 10.10.1170

Organizations using these versions are at risk and should prioritize mitigation efforts.

4. Recommended Mitigation Strategies
