Lifecycle Timeline
1DescriptionCVE.org
Tapo C100/C101 V5 contains a heap-based buffer overflow vulnerability in the RTSP service. An authenticated attacker on the local network can send specially crafted RTSP frame data containing oversized length values, resulting in out-of-bounds heap writes.
Successful exploitation can crash the RTSP service and trigger a device reboot, resulting in a temporary denial-of-service condition.
AnalysisAI
Heap-based buffer overflow in the RTSP service of TP-Link Tapo C100 and C101 V5 IP cameras allows an authenticated attacker on the same local network segment to crash the RTSP service and force a device reboot by sending specially crafted frames with oversized length values. Impact is limited to temporary denial-of-service; no confidentiality or integrity compromise is achievable. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to (1) be present on the same local network segment as the target camera (adjacent network, AV:A - internet-based remote exploitation is not possible), and (2) hold valid authentication credentials for the camera (PR:L - unauthenticated exploitation is not possible per the CVSS vector). … 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:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N) scores 6.9 and accurately characterizes this as a medium-severity, network-adjacent, authenticated availability issue. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained valid credentials for a Tapo C100 or C101 V5 camera - through credential stuffing, default password reuse, or prior network compromise - connects to the camera's RTSP service from the local network and sends a crafted RTSP frame with an oversized length field. The oversized value triggers an out-of-bounds heap write in the RTSP service, causing it to crash and forcing the camera to reboot, eliminating camera coverage for the duration of the reboot cycle. … |
| Remediation | The primary fix is to update affected Tapo C100 V5 and C101 V5 cameras to the patched firmware version published by TP-Link. … Detailed patch versions, workarounds, and compensating controls in full report. |
