CVE-2010-1594 in OCS Inventory NG
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in ocsreports/index.php in OCS Inventory NG 1.02.1 allow remote attackers to inject arbitrary web script or HTML via (1) the query string, (2) the BASE parameter, or (3) the ega_1 parameter. NOTE: some of these details are obtained from third party information.

The vulnerability identified as CVE-2010-1594 represents a critical cross-site scripting weakness in OCS Inventory NG version 1.02.1, specifically within the ocsreports/index.php component. This flaw exposes the system to remote code execution attacks where malicious actors can inject arbitrary web scripts or HTML content into the application's response. The vulnerability manifests through three distinct attack vectors that all originate from improperly sanitized input parameters, making it particularly dangerous as it provides multiple pathways for exploitation. The affected parameters include the query string, BASE parameter, and ega_1 parameter, each representing different entry points where user-supplied data is directly incorporated into the web response without adequate sanitization or encoding measures.
From a technical perspective, this vulnerability falls under CWE-79 which specifically addresses Cross-Site Scripting flaws in web applications. The root cause lies in the application's failure to properly validate and sanitize user input before rendering it in the web interface. When these parameters are manipulated with malicious payloads, the application processes them without implementing proper output encoding or input validation mechanisms, allowing attackers to inject script code that executes in the context of other users' browsers. The vulnerability's severity is amplified by the fact that it affects core functionality of the inventory management system, potentially enabling attackers to hijack user sessions, steal sensitive information, or perform unauthorized actions on behalf of legitimate users.
The operational impact of this vulnerability extends beyond simple script injection, as it can be leveraged to create more sophisticated attacks within the context of the compromised system. Attackers can utilize this vulnerability to establish persistent access through session hijacking, redirect users to malicious sites, or harvest sensitive data from authenticated sessions. The fact that the vulnerability affects multiple parameters increases the attack surface significantly, as different exploitation techniques can be employed depending on the available input vectors. This makes the vulnerability particularly attractive to threat actors as it provides multiple opportunities for successful exploitation, even if one vector is initially blocked or patched.
Security practitioners should implement immediate mitigations including input validation and output encoding for all user-supplied parameters, particularly those used in the affected ocsreports/index.php script. The recommended approach involves implementing strict parameter validation, sanitizing all input data, and applying proper HTML encoding before rendering any user-controllable content. Additionally, organizations should consider implementing web application firewalls to detect and block malicious payloads targeting these specific parameters. The vulnerability also highlights the importance of regular security assessments and patch management, as the affected version of OCS Inventory NG was vulnerable to this class of attack. This incident underscores the critical need for secure coding practices and proper input validation in web applications, aligning with ATT&CK techniques that emphasize the exploitation of input validation weaknesses to achieve persistent access and data exfiltration within enterprise environments.
