CVE 描述
WWBN AVideo is an open source video platform. In versions 26.0 and prior, AVideo's EPG (Electronic Program Guide) feature parses XML from user-controlled URLs and renders programme titles directly into HTML without any sanitization or escaping. A user with upload permission can set a video's epg_link to a malicious XML file whose elements contain JavaScript. This payload executes in the browser of any unauthenticated visitor to the public EPG page, enabling session hijacking and account takeover. </div>

Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).</p></div></div><div class='tw-h5' style='padding-left:10px'>Attack Complexity</div><p style='padding-left:10px'>This metric describes the conditions beyond the attacker’s control that must exist in order to exploit the vulnerability.</p><div style='display:flex;padding-left:10px;'><div style='width:70px;'><p class='text-center bg-gray-800 text-gray-100 rounded'>Low</p></div><div style='flex: 1;margin-left:5px;'><p>Specialized access conditions or extenuating circumstances do not exist.

All the subjects and objects under the jurisdiction of a single security authority are considered to be under one security scope. If a vulnerability in a vulnerable component can affect a component which is in a different security scope than the vulnerable component, a Scope change occurs. Intuitively, whenever the impact of a vulnerability breaches a security/trust boundary and impacts components outside the security scope in which vulnerable component resides, a Scope change occurs.</p><div style='display:flex;padding-left:10px;'><div style='width:70px;'><p class='text-center bg-gray-800 text-gray-100 rounded'>Changed</p></div><div style='flex: 1;margin-left:5px;'><p>An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.</p></div></div><h4 class='bg-light border border-gray-300 rounded p-2'>Base: Impact Metrics</h4><p>The Impact metrics capture the effects of a successfully exploited vulnerability on the component that suffers the worst outcome that is most directly and predictably associated with the attack. Analysts should constrain impacts to a reasonable, final outcome which they are confident an attacker is able to achieve.</p><div class='tw-h5' style='padding-left:10px'>Confidentiality Impact</div><p style='padding-left:10px'>This metric measures the impact to the confidentiality of the information resources managed by a software component due to a successfully exploited vulnerability.</p><div style='display:flex;padding-left:10px;'><div style='width:70px;'><p class='text-center bg-gray-800 text-gray-100 rounded'>Low</p></div><div style='flex: 1;margin-left:5px;'><p>There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.</p></div></div><div class='tw-h5' style='padding-left:10px'>Integrity Impact</div><p style='padding-left:10px'>This metric measures the impact to integrity of a successfully exploited vulnerability. Integrity refers to the trustworthiness and veracity of information.</p><div style='display:flex;padding-left:10px;'><div style='width:70px;'><p class='text-center bg-gray-800 text-gray-100 rounded'>Low</p></div><div style='flex: 1;margin-left:5px;'><p>Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.</p></div></div><div class='tw-h5' style='padding-left:10px'>Availability Impact</div><p style='padding-left:10px'>This metric measures the impact to the availability of the impacted component resulting from a successfully exploited vulnerability.</p><div style='display:flex;padding-left:10px;'><div style='width:70px;'><p class='text-center bg-gray-800 text-gray-100 rounded'>None</p></div><div style='flex: 1;margin-left:5px;'><p>There is no impact to availability within the impacted component.</p></div></div><h4 class='bg-light border border-gray-300 rounded p-2'>Temporal Metrics</h4><p>The Temporal metrics measure the current state of exploit techniques or code availability, the existence of any patches or workarounds, or the confidence in the description of a vulnerability.</p><h4 class='bg-light border border-gray-300 rounded p-2'>Environmental Metrics</h4><p>These metrics enable the analyst to customize the CVSS score depending on the importance of the affected IT asset to a user’s organization, measured in terms of Confidentiality, Integrity, and Availability.</p> </div>
