Exploitation Conditions

Exploitation requires the vSolution Matrix feature to be explicitly enabled - the advisory states the vulnerability only affects devices with this feature active, so it does not apply to default/feature-disabled deployments. The attacker must have network access to the same network segment as the device (CVSS AV:A), meaning an existing LAN foothold or physical/wireless access to that segment. Impact is further limited to devices running versions below 1.78a, and to confidentiality only (capturing displayed presentation content); there is no path to integrity or availability impact. The practical limiting factors are therefore: the non-default Matrix feature requirement, adjacency to the network segment, and any network segmentation/access restrictions already in place around the device.

Impact

This is a genuine but bounded confidentiality exposure, not a top-tier emergency. The CVSS 4.0 vector (AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N, score 7.1) is internally consistent with the description: adjacent-network reach (same network segment), low complexity, no authentication, no user interaction, and high confidentiality impact with zero integrity or availability impact (matching CWE-319 cleartext transmission). No EPSS score was provided, so exploitation probability cannot be quantified. The vulnerability is NOT in CISA KEV and no exploit reference is present, so there is no public exploit identified at time of analysis. The vuln.today decision label is 'this_week' - a prompt-patch priority rather than act_now/emergency - which aligns with the moderate score and the confidentiality-only impact. The key signal that tempers real-world risk is that exploitation is confined to the adjacent network segment (AV:A, not AV:N): an attacker must already be on the same LAN/segment as the device, so this is not internet-wide exploitable. The impact is limited to viewing/capturing presentation screen content, with no code execution or device compromise.

Exploit ScenarioDerived

An attacker who has gained a foothold on the same network segment as a WolfVision Cynap Pro/Cynap Core Pro device with vSolution Matrix enabled connects to the unauthenticated, unencrypted RTSP/RTP stream and silently captures whatever is currently displayed - for example confidential slides, documents, or video shown during a meeting. No credentials or user interaction are needed. No public exploit code is identified, but standard RTSP/RTP clients can consume such a stream without specialized tooling.

AnalysisAIv1 – Oct 26, 2026

Unauthenticated screen-content disclosure in WolfVision Cynap Pro and Cynap Core Pro devices with vSolution Matrix enabled lets hosts on the same network segment view or capture the current presentation through an unencrypted RTSP/RTP stream. The issue affects versions below 1.78a and is limited to confidentiality; the vendor has released 1.78a, and no public exploit was identified at time of analysis. Exposure is bounded by the non-default Matrix feature requirement and network adjacency.

RemediationAI

Upgrade to WolfVision Cynap Pro/Cynap Core Pro version 1.78a or later; the vendor lists a patch as available and the affected range ends below 1.78a (advisory: https://wolfvision.com/de/security/cve-2026-70379-1). If upgrading cannot be done immediately, disable the vSolution Matrix feature where it is not required, which removes the exposed stream but also removes Matrix presentation functionality; otherwise restrict network access so that only trusted hosts on the same segment can reach the device, noting that this is a compensating control while the vendor update addresses the underlying exposure.

Technical ContextAI · show details

The vSolution Matrix feature on WolfVision Cynap Pro and Cynap Core Pro can publish the current screen content as an RTSP/RTP stream to hosts on the same network segment without authentication. Because the stream is unencrypted, CWE-319 (Cleartext Transmission of Sensitive Information) applies: a host with segment adjacency can observe or capture the presentation content where network access is not otherwise restricted. The CVSS:4.0 vector records AV:A/AC:L/AT:N/PR:N/UI:N with VC:H and no VI/VA/SC/SI/SA impact, so the confirmed effect is confidentiality loss from an adjacent, unauthenticated network position; the only stated trigger is the Matrix feature being enabled. CPE scope is cpe:2.3:a:wolfvision:cynap_pro,_cynap_core_pro:*:*:*:*:*:*:*:*.

DescriptionCVE.org

When the vSolution Matrix feature is enabled, affected devices may make current screen content available through an unauthenticated RTSP/RTP stream to hosts on the same network segment. The stream is not encrypted, which may allow an unauthenticated host to view or capture presentation content where network access is not otherwise restricted. This vulnerability only affects devices with the vSolution Matrix feature enabled.

Executive ViewAI

Why It Matters

WolfVision Cynap Pro and Cynap Core Pro devices running vSolution Matrix on versions below 1.78a are vulnerable to unauthenticated screen-content disclosure, allowing any host on the same network segment to view or capture live presentations via an unencrypted RTSP/RTP stream. This poses a confidentiality risk to sensitive visual information-such as board materials, product designs, or client data-displayed during meetings. While exploitation requires network adjacency and the non-default Matrix feature, the absence of a public exploit does not eliminate the need for prompt mitigation, especially in environments where such devices are deployed.
