Lifecycle Timeline
2DescriptionCVE.org
Tapo C100/C101 V5 contains a null pointer dereference vulnerability in the RTSP service. An attacker on the local network can send specially crafted requests that cause the service to dereference an invalid pointer, resulting in a service crash and device reboot. Successful exploitation can disrupt live video streaming functionality and cause a temporary denial-of-service condition.
AnalysisAI
Null pointer dereference in the RTSP service of TP-Link Tapo C100 V5 and C101 V5 IP cameras allows an unauthenticated attacker on the same local network segment to crash the video streaming service and trigger a full device reboot. The flaw is rooted in improper pointer validation during RTSP request parsing (CWE-476), with impact limited strictly to availability - no data exfiltration or configuration tampering is possible. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network adjacency: the attacker must be on the same local network segment or Wi-Fi network as the camera (CVSS AV:A). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N) characterizes this as a low-complexity, unauthenticated, availability-only impact reachable from the adjacent network - a profile consistent with a moderate but contained risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker positioned on the same Wi-Fi or wired LAN segment as the target camera - for example, a guest network user or a compromised IoT device on the same subnet - sends a specially crafted RTSP request to the camera's streaming port. The vulnerable RTSP parser dereferences a null pointer while processing the malformed request, immediately crashing the RTSP service and triggering a full device reboot. … |
| Remediation | The primary remediation is to apply the updated firmware released by TP-Link, available via the official firmware download pages for the Tapo C100 (https://www.tp-link.com/us/support/download/tapo-c100/#Firmware-Release-Notes) and Tapo C101 (https://www.tp-link.com/us/support/download/tapo-c101/#Firmware-Release-Notes), with additional guidance in the vendor FAQ advisory at https://www.tp-link.com/us/support/faq/5251/. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct an inventory of all TP-Link Tapo C100 V5 and C101 V5 cameras across your infrastructure and document their current firmware versions and network locations. …
