CVE-2022-44284: n/a in n/a
Dinstar FXO Analog VoIP Gateway DAG2000-16O is vulnerable to Cross Site Scripting (XSS).
AI Analysis
Technical Summary
CVE-2022-44284 is a Cross Site Scripting (XSS) vulnerability identified in the Dinstar FXO Analog VoIP Gateway DAG2000-16O device. This gateway is used to connect traditional analog telephone lines to Voice over IP (VoIP) networks, facilitating telephony services in enterprise and service provider environments. The vulnerability is classified under CWE-79, indicating that it arises from improper neutralization of input during web page generation, allowing an attacker to inject malicious scripts into web pages viewed by other users. The CVSS 3.1 base score of 5.4 (medium severity) reflects that the vulnerability can be exploited remotely over the network (AV:N), requires low attack complexity (AC:L), but does require privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component. The impact affects confidentiality and integrity to a low degree (C:L, I:L), but does not impact availability (A:N). Exploitation of this XSS vulnerability could allow an attacker to execute arbitrary JavaScript in the context of the gateway's web management interface, potentially leading to session hijacking, unauthorized actions on behalf of legitimate users, or information disclosure. Although no public exploits are currently known, the presence of this vulnerability in a network gateway device that manages telephony infrastructure could have significant security implications if exploited. The lack of vendor or product-specific details and absence of patches at the time of publication suggest that affected organizations should prioritize monitoring and mitigation efforts. The requirement for some level of privileges and user interaction indicates that exploitation might be limited to authenticated users or those able to trick legitimate users into executing malicious payloads via the management interface.
Potential Impact
For European organizations, the exploitation of this XSS vulnerability in Dinstar FXO Analog VoIP Gateways could lead to unauthorized access to telephony management interfaces, potentially compromising call routing, intercepting sensitive call metadata, or enabling further attacks within the network. This could disrupt business communications, lead to leakage of sensitive information, or facilitate fraud through manipulation of telephony services. Given the critical role of VoIP gateways in enterprise telephony and unified communications, any compromise could impact operational continuity and confidentiality. Organizations in sectors with high reliance on telephony infrastructure, such as finance, healthcare, and government, may face increased risks. Additionally, the compromise of such gateways could serve as a foothold for lateral movement within corporate networks, increasing the overall attack surface. The medium severity rating suggests a moderate risk, but the strategic importance of telephony infrastructure elevates the potential impact beyond typical web interface XSS vulnerabilities.
Mitigation Recommendations
1. Restrict access to the Dinstar FXO Analog VoIP Gateway management interface to trusted internal networks and VPNs only, minimizing exposure to untrusted users. 2. Implement strong authentication mechanisms and enforce least privilege principles to limit the number of users with access to the management interface. 3. Educate users with access about the risks of phishing and social engineering attacks that could trigger the required user interaction for exploitation. 4. Monitor network traffic and logs for unusual activity related to the gateway, including unexpected web requests or anomalous configuration changes. 5. If possible, deploy web application firewalls (WAFs) or intrusion prevention systems (IPS) with rules targeting XSS attack patterns on the management interface. 6. Regularly check for vendor updates or patches addressing this vulnerability and apply them promptly once available. 7. Consider segmenting telephony infrastructure from general IT networks to contain potential compromises. 8. Conduct periodic security assessments and penetration tests focusing on VoIP infrastructure to identify and remediate similar vulnerabilities proactively.
