This vulnerability allows a buffer overflow in H3C FA3010L access points SWFA1B0V100R005 due to the lack of length verification related to firewall rule settings. The severity level is classified as medium, with a CVSS score of 5.1. This is significant as organizations using these access points could face risks of remote device crashes or execution of arbitrary commands by attackers.
Risk to organizations includes potential disruption of services and unauthorized control over affected devices, leading to data breaches or further exploitation.
Currently, the vulnerability status is deferred, indicating that there may not be an immediate patch available. Organizations should monitor for updates regarding this issue.
Organizations should prioritize patching immediately to reduce the risk associated with this vulnerability.
Vulnerability Details
The buffer overflow vulnerability in H3C FA3010L access points arises from inadequate length verification when setting firewall rules. The CVSS score of 5.1 indicates a medium severity, with low attack complexity and no privileges required for exploitation. The attack vector is local, meaning exploitation would typically require access to the local network.
The vulnerability affects H3C FA3010L devices running SWFA1B0V100R005 firmware. As of the last modification date, there is no official patch or update provided by the vendor.
The vulnerability is categorized under CWE-120, indicating it is a buffer error. This classification highlights the need for developers to implement proper validation checks to prevent such vulnerabilities.
Technical Analysis
The root cause of this vulnerability is the lack of length verification in the code that processes firewall rule settings. Attackers may exploit this flaw by sending crafted inputs that exceed allocated buffers, leading to unexpected behavior such as device crashes or arbitrary command execution.
The attack vector is local, meaning an attacker must possess local network access to exploit the vulnerability effectively. The attack complexity is considered low, as no special conditions or privileges are required for exploitation.
No user interaction is required for exploitation, making this vulnerability particularly concerning. The confidentiality and integrity impacts are rated as low, with no availability impact noted.
Risk & Impact Analysis
Real-world deployment of H3C FA3010L access points may expose organizations to risks associated with this vulnerability. Successful exploitation could lead to unauthorized access, device crashes, or disruption of network services.
Given the medium severity level, organizations should assess the potential blast radius of this vulnerability. It is crucial to understand whether the affected devices are critical to business operations.
Organizations should schedule remediation as part of their patch cycle to address this vulnerability proactively. Regular vulnerability assessments can help identify similar weaknesses across the network.
