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 exists within Huawei communication devices including DP300, RP200, TE30, TE40, TE50, and TE60 series across multiple firmware versions. The out-of-bounds read flaw represents a critical security weakness that allows remote attackers with authentication credentials to manipulate device behavior through crafted SOAP protocol requests. The vulnerability stems from inadequate input validation mechanisms within the device's web services implementation, specifically affecting the SOAP message processing component that handles remote management communications.
The technical nature of this vulnerability falls under CWE-125, which describes out-of-bounds read conditions where programs access memory locations beyond the bounds of allocated buffers. Attackers can exploit this weakness by sending malformed SOAP packets that trigger memory access violations, potentially leading to process termination or system instability. The authenticated remote attack vector means that an attacker must first establish valid credentials, but once obtained, they can leverage this vulnerability without physical access to the device. This characteristic aligns with ATT&CK technique T1190 which covers exploitation of remote services through authenticated access points.
The operational impact of this vulnerability extends beyond simple service disruption as it can cause process resets that may interrupt critical communication services. In enterprise environments where these devices manage video conferencing, collaboration systems, or network infrastructure, such disruptions can severely impact business continuity and operational efficiency. The vulnerability's potential to cause process resets creates opportunities for denial-of-service conditions that could persist until manual intervention or device reboot occurs. Network administrators face the challenge of identifying compromised devices and implementing remediation measures without disrupting ongoing communications.
Mitigation strategies should prioritize immediate firmware updates from Huawei to address the underlying validation flaws in SOAP message handling. Network segmentation and access control measures can limit the attack surface by restricting unauthorized access to management interfaces. Implementing network monitoring solutions that detect anomalous SOAP traffic patterns can help identify exploitation attempts before they succeed. Security teams should also consider disabling unnecessary remote management services and enforcing strong authentication mechanisms including multi-factor authentication. Regular vulnerability assessments and penetration testing of affected device fleets can help identify additional weaknesses that may compound the risk of this vulnerability. The remediation process must include thorough testing of updated firmware to ensure that security patches do not introduce compatibility issues with existing network infrastructure.
