The vulnerability CVE-2019-17593 represents a cross-site request forgery flaw in JIZHICMS version 1.5.1 that enables unauthorized privilege escalation through the administrative interface. This issue exists within the admin.php/Admin/adminadd.html endpoint which handles administrator account creation functionality. The flaw allows an attacker to construct malicious web pages or send crafted requests that can automatically create new administrator accounts without proper authentication or authorization from legitimate users.
This vulnerability falls under CWE-352, which specifically addresses Cross-Site Request Forgery conditions where web applications fail to validate the origin of requests. The technical implementation of this flaw demonstrates poor input validation and insufficient anti-CSRF protection mechanisms within the application's administrative subsystem. The vulnerability occurs because the application does not verify that requests to create administrator accounts originate from legitimate administrative sessions or contain proper CSRF tokens that would prevent unauthorized execution of administrative functions.
The operational impact of this vulnerability is severe as it directly enables privilege escalation attacks that can completely compromise the affected web application. An attacker who successfully exploits this vulnerability can gain full administrative control over the JIZHICMS installation, allowing them to modify content, access sensitive data, manipulate user accounts, and potentially use the compromised system as a staging ground for further attacks within the network. The vulnerability affects the confidentiality, integrity, and availability of the application by providing unauthorized access to administrative functions that should only be accessible to legitimate administrators.
The attack vector typically involves tricking a logged-in administrator into visiting a malicious website or clicking on a crafted link that automatically submits a request to the vulnerable endpoint. This attack aligns with ATT&CK technique T1078.004 which covers legitimate credentials used for persistence and privilege escalation. Organizations should implement comprehensive CSRF protection mechanisms including anti-CSRF tokens, proper request validation, and referer header checking to prevent such attacks. The mitigation strategy should involve immediate patching of the JIZHICMS application to version 1.5.2 or later, which addresses this specific vulnerability. Additionally, network segmentation, monitoring for unusual administrative account creation events, and regular security audits of administrative interfaces should be implemented to detect and prevent exploitation attempts.
