Summary
by MITRE
Huawei DP300 V500R002C00, RP200 V500R002C00, V600R006C00, TE30 V100R001C10, V500R002C00, V600R006C00, TE40 V500R002C00, V600R006C00, TE50 V500R002C00, V600R006C00, TE60 V100R001C10, V500R002C00, V600R006C00 have a out-of-bounds read vulnerability. Due to insufficient input validation, an authenticated, remote attacker could send malformed SOAP packets to the target device. Successful exploit could make the device access invalid memory and might reset a process.

This vulnerability affects multiple Huawei video conferencing and collaboration devices including DP300, RP200, TE30, TE40, TE50, and TE60 models across various firmware versions. The out-of-bounds read flaw represents a critical security weakness that stems from inadequate input validation mechanisms within the device's SOAP (Simple Object Access Protocol) processing functionality. When these devices receive malformed SOAP packets from authenticated remote attackers, they fail to properly validate the incoming data structure and content, leading to memory access violations that can result in process termination or system instability.
The technical implementation of this vulnerability falls under the CWE-125 weakness category, which specifically addresses out-of-bounds read conditions where programs access memory locations beyond the intended buffer boundaries. This type of vulnerability typically occurs when software does not properly validate array indices or string lengths before accessing memory locations. In the context of Huawei devices, the SOAP processing component fails to validate the length and structure of incoming XML-based messages, allowing attackers to craft malicious payloads that trigger memory access violations when the device attempts to parse and process these malformed packets. The vulnerability can be exploited remotely by authenticated users, meaning that an attacker who has already gained access to the device's administrative interface could leverage this weakness to cause denial of service conditions or potentially escalate privileges.
The operational impact of this vulnerability extends beyond simple denial of service scenarios, as process resets can disrupt critical video conferencing services and communications infrastructure. In enterprise environments where these devices serve as primary communication tools, such vulnerabilities can lead to significant business disruption and potential security breaches. The remote exploitation capability means that attackers do not require physical access to the devices, and the authenticated requirement suggests that compromise of administrative credentials would be sufficient to trigger the vulnerability. This aligns with ATT&CK technique T1078.004 which covers legitimate credentials and T1499.004 for network denial of service attacks. Organizations using these devices face potential risks including service interruption, data exposure, and possible privilege escalation opportunities that could allow attackers to gain deeper system access.
Mitigation strategies should focus on implementing robust input validation mechanisms and applying official firmware updates provided by Huawei to address the identified vulnerability. Network segmentation and access controls should be enforced to limit exposure of these devices to untrusted networks, while monitoring systems should be deployed to detect anomalous SOAP traffic patterns that might indicate exploitation attempts. Additionally, organizations should implement strict administrative credential management practices, including regular password rotation and multi-factor authentication where possible. The vulnerability highlights the importance of secure coding practices and proper input validation in networked devices, particularly those handling XML-based protocols. Regular security assessments and penetration testing should be conducted to identify similar weaknesses in other network components, while incident response procedures should be established to quickly address any exploitation attempts. Given the potential for this vulnerability to be leveraged in broader attack campaigns, organizations should also consider implementing network-based intrusion detection systems to monitor for known exploitation signatures and maintain updated threat intelligence feeds to stay informed about related attack patterns targeting similar devices.
