CVE-2020-7576 in Camstar Enterprise Platform
Summary
by MITRE
A vulnerability has been identified in Camstar Enterprise Platform (All versions), Opcenter Execution Core (All versions < V8.2). An authenticated user with the ability to create containers, packages or register defects could perform stored Cross-Site Scripting (XSS) attacks within the vulnerable software. The impact of this attack could result in the session cookies of legitimate users being stolen. Should the attacker gain access to these cookies, they could then hijack the session and perform arbitrary actions in the name of the victim.

The vulnerability CVE-2020-7576 represents a critical stored cross-site scripting flaw within Camstar Enterprise Platform and Opcenter Execution Core software systems. This security weakness affects all versions of these industrial automation platforms and specifically targets authenticated users who possess privileges to create containers, packages, or register defects within the system. The vulnerability stems from insufficient input validation and output encoding mechanisms that fail to properly sanitize user-supplied data before it is stored and subsequently rendered in web interfaces. The flaw exists at the application level where user inputs are not adequately filtered or escaped, creating an environment where malicious scripts can be persistently injected into the system's database or storage mechanisms.
The technical implementation of this vulnerability allows an attacker with minimal privileges to execute persistent XSS attacks by injecting malicious script code through legitimate system interfaces used for container, package, or defect registration. When other users view the affected data, the malicious scripts execute in their browser context, potentially stealing session cookies and other sensitive information. This stored XSS vector operates through the standard web application request-response cycle where the malicious payload is first submitted by the attacker, stored within the application's data repository, and then executed when legitimate users access the affected content. The vulnerability is particularly dangerous because it does not require the victim to interact with malicious links directly, instead exploiting the trust relationship between the user and the application.
The operational impact of CVE-2020-7576 extends beyond simple data theft to enable full session hijacking capabilities that can lead to complete system compromise. An attacker who successfully steals session cookies can impersonate legitimate users and perform unauthorized actions within the Camstar platform, potentially accessing sensitive manufacturing data, altering production processes, modifying quality control records, or executing commands that could disrupt industrial operations. The attack chain follows the typical pattern of credential theft and privilege escalation as outlined in the ATT&CK framework under the credential access and privilege escalation domains. This vulnerability particularly affects industrial environments where these platforms manage critical manufacturing processes and quality control systems, making the potential impact on operational technology systems significant.
Organizations should implement multiple layers of mitigation strategies to address this vulnerability effectively. The primary remediation involves implementing comprehensive input validation and output encoding mechanisms that sanitize all user-supplied data before storage and rendering. This includes applying proper HTML escaping, implementing Content Security Policies, and ensuring that all user inputs are validated against strict whitelists of acceptable characters and formats. Security patches should be deployed immediately to all affected versions of Camstar Enterprise Platform and Opcenter Execution Core, with particular attention to versions prior to V8.2. Additionally, organizations should consider implementing web application firewalls to detect and block malicious script injection attempts, establish monitoring protocols for suspicious user activities, and conduct regular security assessments to identify similar vulnerabilities in other industrial control systems. The vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws, and represents a significant concern for organizations implementing industrial cybersecurity measures under NIST cybersecurity frameworks.
