CVE-2025-34058: CWE-521 Weak Password Requirements in Hangzhou Hikvision System Technology Streaming Media Management Server
Hikvision Streaming Media Management Server v2.3.5 uses default credentials that allow remote attackers to authenticate and access restricted functionality. After authenticating with these credentials, an attacker can exploit an arbitrary file read vulnerability in the /systemLog/downFile.php endpoint via directory traversal in the fileName parameter. This exploit chain can enable unauthorized access to sensitive system files.
AI Analysis
Technical Summary
CVE-2025-34058 is a high-severity vulnerability affecting Hangzhou Hikvision System Technology's Streaming Media Management Server version 2.3.5. The core issue stems from weak password requirements, specifically the use of default credentials that are not changed or enforced to be strong. This allows remote attackers to authenticate without prior authorization. Once authenticated using these default credentials, an attacker can exploit an arbitrary file read vulnerability present in the /systemLog/downFile.php endpoint. This endpoint is vulnerable to directory traversal attacks through the fileName parameter, enabling attackers to access sensitive system files outside the intended directory scope. The vulnerability combines two CWE weaknesses: CWE-521 (Weak Password Requirements) and CWE-22 (Improper Limitation of a Pathname to a Restricted Directory). The CVSS 4.0 base score of 8.7 reflects the high impact and ease of exploitation, as no privileges or user interaction are required, and the attack vector is network-based. The vulnerability can lead to unauthorized disclosure of sensitive information, potentially including configuration files, logs, or credentials, which could further facilitate lateral movement or privilege escalation within affected environments. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that affected organizations should prioritize mitigation and monitoring to prevent exploitation.
Potential Impact
For European organizations, this vulnerability poses a significant risk, especially for those using Hikvision's Streaming Media Management Server in their video surveillance infrastructure. Unauthorized access to sensitive system files could expose critical operational data, user credentials, or configuration details, undermining the confidentiality and integrity of security systems. This could lead to unauthorized surveillance, tampering with video feeds, or disruption of security monitoring capabilities. Given the widespread use of Hikvision products in public safety, transportation, and critical infrastructure sectors across Europe, exploitation could have cascading effects on physical security and data privacy compliance, including GDPR obligations. The vulnerability's network-exploitable nature increases the risk of remote compromise without requiring user interaction, making it a potent threat for organizations with exposed or poorly segmented networks.
Mitigation Recommendations
Organizations should immediately audit their deployments of Hikvision Streaming Media Management Server version 2.3.5 to identify instances using default or weak credentials. Changing all default passwords to strong, unique passwords is critical. Implementing network segmentation to isolate management interfaces from general network access can reduce exposure. Employing strict access control lists (ACLs) and firewall rules to limit access to the streaming media management server to trusted IP addresses will further reduce risk. Monitoring logs for unusual authentication attempts or file access patterns targeting /systemLog/downFile.php can help detect exploitation attempts early. Since no official patches are currently available, organizations should engage with Hikvision support for updates or consider temporary mitigation such as disabling the vulnerable endpoint if feasible. Additionally, integrating multi-factor authentication (MFA) for administrative access, if supported, will add a layer of defense against unauthorized access.
