Exploitation Conditions

Exploitation requires that the MICE (Miracast over Infrastructure Connection Establishment) service be explicitly enabled by the customer - it is disabled in the default configuration, so default deployments are not exposed. Given CVSS PR:N/UI:N, no authentication or user interaction is required once MICE is reachable, and the attacker needs only network access to the MICE service to saturate its connection capacity. Impact is limited to denial of service and persists only while the attack continues; Miracast P2P is explicitly not affected and remains available independently of MICE on most devices. The main limiting factors are the non-default MICE configuration and network reachability to the service; a complete Miracast disruption only occurs on some devices when WLAN is configured for Infrastructure mode.

Impact

This is a genuine but modest-priority availability issue, not a high-impact emergency. The vendor CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) describes a remotely reachable, low-complexity, unauthenticated condition, but the only impact metric set is VA:L - availability-low, with no confidentiality (VC:N) or integrity (VI:N) effect and no scope change to other systems - which caps severity at 6.9. CWE-400 (uncontrolled resource consumption) matches the description: an attacker exhausts MICE connection capacity to block legitimate Miracast-over-Infrastructure connections only while the attack persists; there is no indication of code execution, data exposure, or lasting state corruption. The exploitation signals reinforce a measured response: EPSS is 0.31% (23rd percentile), the CVE is not listed in CISA KEV, and no public exploit is referenced, so there is no public exploit identified at the time of analysis. These signals are mutually consistent (low probability, no active exploitation, no PoC), so there is no conflict to flag - the vuln.today 'this_month' decision label fits a patchable, low-footprint DoS rather than an act-now scenario. The principal real-world limiter is that MICE is disabled by default and must be explicitly enabled by the customer, which sharply narrows the exposed population. Note one caveat: CVSS AV:N/PR:N describes network-reachable unauthenticated severity but does not encode the non-default-configuration prerequisite, so the raw vector overstates exposure for default deployments - verify MICE enablement before prioritizing.

Exploit ScenarioDerived

An attacker with network reachability to a WolfVision Cynap device that has the optional MICE service enabled repeatedly opens or holds MICE connections to consume the service's finite connection capacity. Legitimate users are then unable to establish Miracast-over-Infrastructure sessions for the duration of the attack, and on some devices configured for WLAN Infrastructure mode this can disrupt Miracast entirely. No public exploit is identified at the time of analysis, and the attack requires that the non-default MICE service first be enabled.

AnalysisAIv1 – Oct 28, 2026

Connection-capacity exhaustion in the MICE (Miracast over Infrastructure Connection Establishment) service on WolfVision Cynap collaboration devices lets an unauthenticated remote attacker with network reachability to that service occupy its available connection slots, so legitimate users cannot establish MICE-based Miracast sessions while the condition persists. Exposure is bounded: MICE is disabled in the default configuration and must be explicitly enabled by the customer, and Miracast P2P is unaffected and remains available independently of MICE on most devices, although a complete Miracast disruption can occur on some units when WLAN is configured for Infrastructure mode. EPSS is 0.31% (23rd percentile), no public exploit has been identified at time of analysis, and vendor patches are available for the version branches that list fixed releases.

RemediationAI

Upgrade to the fixed firmware for each branch: Cynap Videobar 1.72e or later, Cynap Pure (Next Gen) 2.00d or later, and Cynap Pro, Cynap Core Pro, Cynap Pure, Cynap Pure Mini and Cynap Pure Pro 1.78a or later; for the Cynap, Cynap Core and Cynap Pure SDM branch the available data lists no fixed version, so confirm the target release against the vendor advisory at https://wolfvision.com/de/security/cve-2026-70380-1 before upgrading. Because MICE is disabled by default, the most effective compensating control is to leave it disabled unless Miracast over Infrastructure is genuinely required - the trade-off is loss of the MICE transport, while Miracast P2P remains available independently on most devices. Where MICE must stay enabled, restrict network reachability to the MICE service to trusted client segments and prevent untrusted hosts from reaching it, accepting that this narrows the set of devices able to use MICE-based Miracast; note that devices with WLAN in Infrastructure mode can lose Miracast entirely if MICE capacity is saturated, so those units should be prioritized for the firmware update.

Technical ContextAI · show details

The flaw is a CWE-400 uncontrolled resource consumption issue in the MICE service, the component that implements Miracast over Infrastructure (MS-MICE) on WolfVision Cynap devices. MICE is an alternative to the classic Wi-Fi Direct (P2P) transport: instead of building a direct wireless link between source and sink, it carries the Miracast session over an existing IP infrastructure network, which means the sink-side service must accept and track inbound connection requests from the network. That connection-tracking state is finite, and the advisory describes an attacker consuming the available connection capacity so that legitimate MICE-based sessions can no longer be established; per the supplied CVSS vector (AV:N/AC:L/AT:N/PR:N/UI:N with availability-only impact), no authentication or user interaction is required once the MICE service is reachable, and the effect lasts only while the condition persists. The sources do not describe the specific request sequence or message handling defect used to hold capacity, so the trigger beyond generic capacity exhaustion is not described in the available sources. Scope is deliberately narrow in the advisory: Miracast P2P is explicitly not affected, MICE ships disabled by default, and a total loss of Miracast functionality arises only on some devices where WLAN is configured for Infrastructure mode alongside MICE.

DescriptionCVE.org

A denial-of-service vulnerability has been identified in the Miracast over Infrastructure Connection Establishment (MICE) service. An unauthenticated attacker with network access to the MICE service could consume available connection capacity, preventing legitimate users from establishing MICE-based Miracast connections while the condition persists. Miracast P2P is not affected. MICE is disabled in the default configuration and must be explicitly enabled by the customer. On most devices, Miracast P2P is available independently of MICE, but a complete disruption of Miracast can occur on some devices when WLAN is configured for Infrastructure mode.
