The vulnerability CVE-2017-11583 represents a critical sql injection flaw in dayrui FineCms version 5.0.9 that specifically targets the catid parameter within the action=related request processed by the libraries/Template.php component. This issue falls under the common weakness enumeration CWE-89 which categorizes sql injection vulnerabilities as a serious threat to database security. The flaw enables remote attackers to execute arbitrary sql commands against the underlying database system by manipulating the catid parameter, potentially leading to complete database compromise.
The technical exploitation occurs when the application fails to properly sanitize or escape user input before incorporating it into sql query construction within the Template.php library. When a malicious user submits a request with a crafted catid parameter, the application directly incorporates this unvalidated input into database queries without adequate input validation or parameterization. This allows attackers to inject malicious sql code that can manipulate database structures, extract sensitive information, or even execute administrative commands on the database server.
The operational impact of this vulnerability extends beyond simple data theft, as successful exploitation can result in complete system compromise and unauthorized access to sensitive organizational data. Attackers can leverage this vulnerability to perform data exfiltration, modify or delete critical database records, escalate privileges within the application, or establish persistent access points. The vulnerability affects the core content management functionality of FineCms, potentially compromising all content managed through the system and exposing user credentials, personal information, and business data. This type of vulnerability is particularly dangerous in web applications as it allows for automated exploitation and can be easily discovered through routine security scanning.
Mitigation strategies for CVE-2017-11583 should include immediate patching of the FineCms application to version 5.0.10 or later where this vulnerability has been addressed. Organizations should implement proper input validation and parameterized queries throughout the application to prevent similar issues in the future. Database access controls should be reviewed and restricted to minimize potential damage from successful attacks. The vulnerability aligns with ATT&CK technique T1071.004 which covers application layer protocol manipulation, and T1190 which involves exploitation of remote services. Network segmentation and intrusion detection systems should be configured to monitor for suspicious parameterized requests, particularly those targeting known vulnerable endpoints. Additionally, implementing web application firewalls and regular security code reviews can help prevent similar injection vulnerabilities from being introduced in future development cycles.
