CVE-2024-25063: Hikvision Hikcentral Auth Bypass Flaw

CVE-2024-25063 Overview

CVE-2024-25063 is an authorization bypass vulnerability affecting Hikvision HikCentral Professional, a widely deployed video management platform used for centralized surveillance and security operations. Due to insufficient server-side validation, a successful exploit of this vulnerability could allow an attacker to gain access to certain URLs that the attacker should not have access to.

This vulnerability stems from improper authorization controls (CWE-285) where the application fails to adequately verify user permissions before granting access to restricted resources. An unauthenticated remote attacker can exploit this flaw over the network to access sensitive endpoints and potentially exfiltrate confidential data from the video management system.

Critical Impact

Attackers can bypass authorization controls to access restricted URLs, potentially exposing sensitive surveillance data, configuration information, and system resources without authentication.

Affected Products

• Hikvision HikCentral Professional (versions prior to patched releases)
• Video management system deployments using vulnerable HikCentral Professional versions
• Enterprise surveillance infrastructure relying on affected components

Technical Details for CVE-2024-25063

Vulnerability Analysis

This vulnerability is classified as Improper Authorization (CWE-285), indicating that the HikCentral Professional application does not properly verify whether a user has the necessary permissions to access specific resources. The flaw exists in the server-side validation logic responsible for enforcing access controls on URL endpoints.

When an attacker sends crafted HTTP requests to the vulnerable HikCentral Professional server, the application fails to adequately validate authorization tokens or session credentials before serving protected content. This allows unauthorized access to restricted functionality and sensitive data that should only be available to authenticated administrators or privileged users.

The network-based attack vector means exploitation can occur remotely without requiring local access to the target system. The vulnerability requires no user interaction and can be exploited without any privileges, making it particularly dangerous for internet-exposed HikCentral deployments.

Root Cause

The root cause of CVE-2024-25063 lies in insufficient server-side validation within the HikCentral Professional web application. The authorization logic fails to properly verify user credentials and permission levels before processing requests for protected resources. This design flaw allows attackers to bypass intended access restrictions by directly requesting URLs that should require authentication or elevated privileges.

Attack Vector

The attack vector for this vulnerability is network-based, allowing remote exploitation. An attacker can target any HikCentral Professional instance accessible over the network by crafting HTTP requests to restricted URL endpoints. The exploitation does not require authentication, user interaction, or any special privileges, making it straightforward for attackers to exploit.

The attack workflow typically involves:

1. Reconnaissance to identify HikCentral Professional deployments
2. Enumeration of application endpoints and URL structures
3. Direct requests to restricted URLs without proper authentication
4. Extraction of sensitive data or access to protected functionality

Since no verified code examples are available for this vulnerability, administrators should refer to the Hikvision Security Advisory for technical details on affected endpoints and exploitation mechanics.

Detection Methods for CVE-2024-25063

Indicators of Compromise

• Unusual HTTP requests to administrative or restricted URL paths from unauthenticated sources
• Access log entries showing successful responses (HTTP 200) to protected endpoints without valid session tokens
• Anomalous data exfiltration patterns from HikCentral Professional servers
• Unexpected access to video feeds, configuration files, or user management endpoints

Detection Strategies

• Monitor web server access logs for requests to administrative endpoints lacking authentication headers
• Implement web application firewall (WAF) rules to detect and block unauthorized access attempts to restricted URLs
• Deploy intrusion detection systems (IDS) with signatures for HikCentral-specific exploitation patterns
• Enable verbose logging on HikCentral Professional to capture detailed request information for forensic analysis

Monitoring Recommendations

• Establish baseline traffic patterns for HikCentral Professional and alert on deviations
• Monitor network traffic for unusual volume or patterns targeting the HikCentral web interface
• Implement SIEM correlation rules to identify potential authorization bypass attempts
• Regularly audit access logs for evidence of unauthorized resource access

How to Mitigate CVE-2024-25063

Immediate Actions Required

• Update Hikvision HikCentral Professional to the latest patched version immediately
• Restrict network access to HikCentral Professional servers using firewall rules and network segmentation
• Implement additional authentication layers such as VPN requirements for remote access
• Review access logs for evidence of prior exploitation attempts
• Conduct a security audit of all HikCentral Professional deployments in your environment

Patch Information

Hikvision has released security updates to address this vulnerability. Administrators should review the Hikvision Security Advisory for detailed patching instructions and download links for the corrected software versions.

It is critical to apply the vendor-supplied patches as soon as possible, as this vulnerability allows unauthenticated remote attackers to access restricted resources.

Workarounds

• Place HikCentral Professional servers behind a reverse proxy with additional authentication requirements
• Implement network-level access controls to restrict which IP addresses can reach the HikCentral interface
• Disable unnecessary services and endpoints on the HikCentral Professional server
• Use VPN-only access policies for all remote connections to surveillance infrastructure
