The CVE-2015-2347 vulnerability represents a critical cross-site scripting flaw discovered in Huawei SEQ Analyst software prior to version V200R002C03LG0001CP0022. This vulnerability resides within the web application interface of the Huawei SEQ Analyst system, which is designed for network security monitoring and analysis. The flaw specifically affects the flexdata.action endpoint, which processes XML command requests from various modules including common, monitor, and psnpm directories. The vulnerability stems from insufficient input validation and sanitization of XML elements within the request parameters, creating an exploitable entry point for malicious actors to inject arbitrary web scripts into the application's response.
The technical implementation of this vulnerability occurs through the manipulation of XML elements within the req parameter of the flexdata.action endpoint. Attackers can exploit this weakness by crafting malicious XML payloads containing script tags or other malicious code within the command XML element or module XML element. When the vulnerable application processes these requests without proper sanitization, the injected code executes within the context of other users' browsers who access the affected pages. This allows attackers to perform actions such as stealing session cookies, redirecting users to malicious sites, or executing unauthorized commands on behalf of legitimate users.
The operational impact of this vulnerability extends beyond simple script injection, as it provides attackers with persistent access to the affected system's web interface. Given that SEQ Analyst is designed for network security monitoring, successful exploitation could enable attackers to gain unauthorized access to sensitive network monitoring data, potentially compromising the integrity of security operations. The vulnerability affects multiple functional modules within the application, increasing the attack surface and making it more difficult to secure the system comprehensively. Security professionals should note that this vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications, and follows the ATT&CK technique T1059.007 for script execution through web interfaces.
Mitigation strategies for CVE-2015-2347 should prioritize immediate software updates to Huawei SEQ Analyst version V200R002C03LG0001CP0022 or later, which contains the necessary patches to address the input validation issues. Organizations should implement comprehensive input sanitization measures, including XML schema validation and strict parameter filtering, to prevent malicious payloads from being processed. Network segmentation and access controls should be strengthened to limit exposure of the vulnerable application to untrusted networks. Additionally, regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other components of the security infrastructure. The vulnerability demonstrates the critical importance of input validation in web applications and serves as a reminder of the potential consequences when security controls fail in security monitoring tools that are meant to protect network environments.
