CVE-2024-51398 is a vulnerability identified in the Altai X500 Indoor 22 802.11ac Wave 2 Access Point's web management interface. The core issue is the leakage of weak passwords through background processes, which can be exploited by attackers to gain unauthorized access to the device's management functions. This vulnerability is classified under CWE-521, indicating the use of weak passwords that can be easily compromised. The CVSS v3.1 base score is 6.5, reflecting a medium severity level. The attack vector is adjacent network (AV:A), meaning the attacker must have access to the local network or a connected network segment. The attack complexity is low (AC:L), requiring no special conditions, and no privileges (PR:N) or user interaction (UI:N) are needed to exploit it. The scope is unchanged (S:U), and the impact is primarily on confidentiality (C:H), with no direct impact on integrity (I:N) or availability (A:N). This means attackers can potentially steal sensitive information such as passwords or configuration data but cannot modify or disrupt device operations directly. The vulnerability poses a serious threat to network security because unauthorized access to the management interface can lead to further network attacks or data breaches. Although no patches or exploits are currently reported, the absence of a patch increases the urgency for mitigation. The Altai X500 AP is used in enterprise and industrial wireless deployments, making this vulnerability relevant for organizations relying on these devices for critical network infrastructure.

The vulnerability allows attackers to obtain weak passwords leaked by the device, enabling unauthorized access to the management interface of Altai X500 APs. This unauthorized access can lead to data theft, including sensitive network configuration and credentials, potentially facilitating further network attacks such as lateral movement, network reconnaissance, or man-in-the-middle attacks. While the vulnerability does not directly affect system integrity or availability, the confidentiality breach can have cascading effects on overall network security. Organizations with these devices in their wireless infrastructure risk exposure of critical network management functions, which can undermine trust in network security and compliance with data protection regulations. The medium severity score reflects the balance between the ease of exploitation and the impact limited to confidentiality. However, the real-world impact could be significant if attackers leverage this access to compromise broader network segments or sensitive data. The lack of known exploits in the wild suggests the vulnerability is not yet actively exploited, but the presence of weak password leakage is a common and attractive target for attackers.

1. Immediately restrict access to the management interface of Altai X500 APs to trusted network segments only, preferably via VLAN segmentation or firewall rules. 2. Implement strong password policies and change any default or weak passwords on the affected devices to complex, unique credentials. 3. Monitor network traffic for unusual access patterns or attempts to connect to the management interface, using intrusion detection systems or network monitoring tools. 4. Disable or limit background services that may leak password information if configurable. 5. Regularly audit device configurations and firmware versions to detect unauthorized changes or updates. 6. Contact Altai Technologies for any available patches or firmware updates addressing this vulnerability and apply them promptly once released. 7. Employ multi-factor authentication (MFA) for management access if supported by the device. 8. Educate network administrators about the risks of weak passwords and the importance of securing management interfaces. 9. Consider isolating management interfaces physically or logically from general user networks to reduce exposure. 10. Maintain an incident response plan to quickly address any detected compromise related to this vulnerability.
