The vulnerability identified as CVE-2017-14192 resides within the dayrui FineCms content management system version 5.0.11, specifically within the checktitle function located in controllers/member/api.php. This flaw represents a cross-site scripting vulnerability that emerges from inadequate input validation and sanitization of user-supplied data. The vulnerability is particularly concerning as it affects the module field, which suggests that malicious actors could potentially inject malicious scripts through this parameter when interacting with the member API endpoints.
The technical implementation of this vulnerability stems from the checktitle function's failure to properly sanitize or escape user input before processing or returning it within the web application's response. When a user submits data through the module field parameter, the application does not adequately validate or sanitize this input, allowing potentially malicious script code to persist within the application's processing logic. This creates an environment where attacker-controlled content can be executed within the context of other users' browsers who view the affected content, making it a classic persistent cross-site scripting vulnerability.
The operational impact of this vulnerability extends beyond simple script execution, as it can enable attackers to perform a range of malicious activities including session hijacking, credential theft, data exfiltration, and redirection to malicious websites. The vulnerability's presence in the member API controller suggests that authenticated users could exploit this weakness to compromise other users' sessions or manipulate the application's behavior. Attackers could craft malicious payloads that would execute when other users view content or interact with the affected system components, potentially leading to full system compromise or unauthorized data access.
From a cybersecurity perspective, this vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws, and follows patterns commonly associated with ATT&CK technique T1059.001 for command and scripting interpreter. The vulnerability demonstrates poor input validation practices and inadequate output encoding, which are fundamental security weaknesses that should be addressed through proper application security controls. Organizations using dayrui FineCms 5.0.11 should consider immediate remediation through input validation, output encoding, and proper sanitization of all user-supplied data before processing or rendering within the application's user interface. The vulnerability serves as a reminder of the critical importance of implementing comprehensive security measures throughout all application layers, particularly in API endpoints that handle user input, to prevent exploitation through common web application vulnerabilities.
