The CVE-2010-4979 vulnerability represents a critical sql injection flaw within the CANDID content management system that specifically targets the image/view.php component. This vulnerability arises from insufficient input validation and sanitization of the image_id parameter, which is directly incorporated into sql query constructions without proper escaping or parameterization. The flaw exists in the web application's data handling logic where user-supplied input flows directly into database queries without adequate security controls, creating an exploitable path for malicious actors to manipulate the underlying database operations.
The technical implementation of this vulnerability stems from the application's failure to properly sanitize user input before incorporating it into sql statements. When an attacker submits a crafted image_id parameter containing sql payload characters, the application processes this input directly within the sql query context. This lack of input validation creates a condition where malicious sql commands can be executed with the privileges of the web application's database user account. The vulnerability specifically affects the image/view.php script which handles image retrieval operations, making it a high-value target for attackers seeking to access or manipulate the system's media database.
From an operational perspective, this vulnerability enables remote attackers to execute arbitrary sql commands against the affected database, potentially leading to complete system compromise. Attackers can leverage this flaw to extract sensitive information from the database, modify or delete records, and potentially escalate privileges to gain deeper system access. The impact extends beyond simple data theft as the vulnerability can be used to establish persistent access, modify application behavior, or even facilitate further attacks within the network. The remote nature of this vulnerability means that attackers do not require physical access to the system and can exploit it from anywhere on the internet.
The vulnerability aligns with CWE-89 which specifically addresses sql injection flaws in software applications, and maps to attack techniques within the ATT&CK framework under T1071.004 for application layer protocol manipulation and T1046 for remote service exploitation. Organizations utilizing CANDID systems should immediately implement input validation controls, parameterized queries, and proper output encoding to prevent sql injection attacks. Recommended mitigations include implementing web application firewalls, conducting thorough input sanitization, and applying database access controls to limit the privileges of application database accounts. Additionally, regular security assessments and code reviews should be performed to identify and remediate similar vulnerabilities in other application components that may be susceptible to sql injection attacks through improper input handling practices.
