CVE-2024-24906 in Secure Connect Gateway
Summary
by MITRE • 03/01/2024
Dell Secure Connect Gateway (SCG) Policy Manager, all versions, contain(s) a Stored Cross-Site Scripting Vulnerability in Policy page. An adjacent network high privileged attacker could potentially exploit this vulnerability, leading to the storage of malicious HTML or JavaScript codes in a trusted application data store. When a victim user accesses the data store through their browsers, the malicious code gets executed by the web browser in the context of the vulnerable web application. Exploitation may lead to information disclosure, session theft, or client-side request forgery.

The vulnerability identified as CVE-2024-24906 affects Dell Secure Connect Gateway Policy Manager across all supported versions, representing a critical stored cross-site scripting flaw that resides within the policy management interface. This weakness specifically manifests in the policy page component of the application, where user input is improperly sanitized and stored without adequate validation mechanisms. The vulnerability stems from insufficient output encoding and input validation controls that fail to properly filter malicious content before it is persisted in the application's data store, creating a persistent threat vector that can be exploited by attackers who have network access to the system.
The technical exploitation of this vulnerability requires an attacker to be positioned within the same network segment as the affected system, typically classified as a high privileged adjacent network attacker due to the requirement for network proximity. This configuration aligns with common attack patterns described in the ATT&CK framework under the technique of credential access and privilege escalation through network-based attacks. The flaw operates by accepting malicious HTML or JavaScript payloads through the policy management interface, which are then stored in the application's backend database or configuration files. When legitimate users navigate to pages that display this stored content, the malicious code executes within the victim's browser context, effectively bypassing normal security boundaries and operating under the privileges of the vulnerable web application.
The operational impact of this vulnerability extends beyond simple script execution, as it creates a persistent threat that can be leveraged for various malicious activities including information disclosure, session hijacking, and client-side request forgery operations. Attackers can potentially steal sensitive session cookies, access confidential policy information, or manipulate the application's behavior to redirect users to malicious sites. This type of vulnerability directly impacts the confidentiality, integrity, and availability of the system's policy management functions, as demonstrated by the CWE-79 classification for cross-site scripting vulnerabilities. The stored nature of this flaw means that even after the initial exploitation, the malicious code remains persistent and can affect multiple users over time, making it particularly dangerous in enterprise environments where policy management systems are frequently accessed by authorized personnel.
Mitigation strategies for CVE-2024-24906 should focus on immediate implementation of input validation and output encoding controls within the policy management interface. Organizations should implement proper HTML sanitization routines that filter or escape potentially dangerous characters and tags before storing user-supplied content. Network segmentation and access controls should be reinforced to limit adjacent network access to privileged systems, while also implementing monitoring solutions that can detect anomalous behavior in policy management interfaces. The vulnerability's classification as a stored XSS issue aligns with ATT&CK techniques related to web application attacks and credential access, making comprehensive network monitoring and application security controls essential. Regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other application components, while also ensuring that all Dell Secure Connect Gateway installations are updated to the latest security patches provided by Dell to address this specific weakness.
