The vulnerability identified as CVE-2024-57482 affects H3C N12 V100R005 devices within 5G wireless network processing functions, representing a critical security flaw that undermines the integrity and availability of network infrastructure. This buffer overflow vulnerability stems from insufficient input validation mechanisms within the device's web interface processing module, specifically in the /bin/webs endpoint that handles POST requests. The absence of proper length verification creates an exploitable condition where malicious inputs can exceed allocated buffer boundaries, leading to unpredictable system behavior and potential compromise of the affected device.
The technical implementation of this vulnerability resides in the web server component of the H3C N12 device, where the /bin/webs binary processes incoming HTTP POST requests without adequate bounds checking on user-supplied data. When an attacker crafts a malicious POST request containing oversized payload data, the processing function fails to validate the input length against the allocated buffer space, resulting in memory corruption that can manifest as stack or heap overflow conditions. This flaw aligns with CWE-121, which describes stack-based buffer overflow conditions, and CWE-122, which addresses heap-based buffer overflow scenarios, both of which are common attack vectors in network device exploitation.
The operational impact of this vulnerability extends beyond simple device instability, as successful exploitation can lead to complete system compromise through arbitrary code execution capabilities. Attackers can leverage this vulnerability to remotely crash the target device, rendering the 5G wireless network service unavailable, or more critically, execute malicious code with elevated privileges on the affected system. The remote nature of the attack vector eliminates the need for physical access or local network presence, making the vulnerability particularly dangerous for enterprise and telecommunications environments where such devices serve as critical infrastructure components. This vulnerability directly maps to ATT&CK technique T1203, which covers exploitation for execution through remote code injection attacks, and T1499, which addresses network denial of service through device compromise.
Organizations utilizing H3C N12 V100R005 devices should implement immediate mitigations including firmware updates from H3C to address the buffer overflow condition, network segmentation to limit access to the vulnerable /bin/webs endpoint, and monitoring for suspicious POST request patterns targeting the affected interface. Additionally, implementing web application firewalls and intrusion detection systems can help identify and block malicious traffic attempting to exploit this vulnerability. The remediation process should include thorough vulnerability assessment of all network devices running similar firmware versions to identify potential exposure to similar buffer overflow conditions. Security teams should also consider implementing network access controls that restrict administrative access to only trusted sources and establish incident response procedures to address potential exploitation attempts.
