CVE-2013-5223 identifies multiple cross-site scripting (XSS) vulnerabilities in the D-Link DSL-2760U Gateway (Rev. E1). These vulnerabilities allow remote authenticated users to inject arbitrary web scripts or HTML through various parameters in the device's configuration pages. With a CVSS score of 5.4, categorized as medium severity, this vulnerability presents a notable risk to organizations using affected devices. Due to the nature of XSS, attackers may exploit these vulnerabilities to execute scripts in the context of the user’s session, potentially leading to unauthorized actions.
The exploitation status of CVE-2013-5223 indicates that it is included in the Known Exploited Vulnerabilities (KEV) catalog, which highlights its relevance in active threat landscapes. Organizations should prioritize patching immediately to mitigate potential exploitation.
Risk to organizations includes unauthorized access to sensitive configurations and potential manipulation of device behavior, which could disrupt services or compromise security. Given the ongoing exploration of such vulnerabilities, timely remediation is essential.
Organizations must remain vigilant regarding vulnerabilities like CVE-2013-5223, as they can lead to severe consequences if left unaddressed.
Vulnerability Details
The official CVE description notes multiple XSS vulnerabilities within D-Link DSL-2760U Gateway, which allow remote authenticated users to inject arbitrary web scripts or HTML via specific parameters. The vulnerabilities are classified under CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')).
The CVSS score for this vulnerability is 5.4, indicating medium severity. This score highlights the potential impact of exploitation, where the attack vector is classified as NETWORK, and the attack complexity is low, requiring only low privileges and user interaction. Organizations are advised to review their configurations to ensure the security of their devices.
Technical Analysis
The root cause of these vulnerabilities lies in improper input validation on the affected parameters, which can be exploited through crafted requests. The attack vector is network-based, allowing remote access to the device without requiring physical proximity. The complexity of the attack is low, as it does not necessitate advanced skills or tools, making it accessible to a range of attackers.
User interaction is required, as the targeted user must be authenticated and initiate the request containing the malicious payload. The confidentiality and integrity impacts are both low, while availability impact is nonexistent.
Risk & Impact Analysis
The real-world deployment risk of CVE-2013-5223 is significant due to the potential for unauthorized script execution within the context of authenticated users. This could lead to further exploitation, such as phishing attacks or data leakage, affecting organizational security. The blast radius is substantial, especially for organizations utilizing this gateway in sensitive environments.
Urgency assessment based on the CVSS score suggests that organizations should address this vulnerability in their priority patch cycle to mitigate risks effectively.
