The vulnerability is known to have been exploited in the wild by the Mirai_ptea (Rimasuta) and Mirai_aurora botnets for malware propagation and subsequent DDoS activity. The vulnerability was reported to affect firmware dating from 2016, while firmware released after 2017 appears to mitigate the issue by restricting the affected service to the localhost interface (127.0.0.1) instead of exposing it on all interfaces (0.0.0.0).
The affected-device list reported by Netlab includes many D1004NR, D1008NR, D1016NR, D1104, D1104NR, D1108NR, D1116NR, D1132NR, D2116NR, D97xx, D98xx, and D99xx variants and several associated hardware revisions
The exploit is included in some version of rapperbot and exploited in 2026. This assignment has been made to document the active exploitation and lack of documentation from the vendor.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

| Description | Certain KGUARD DVR devices running vulnerable firmware expose a system command execution service on all network interfaces without requiring authentication. A remote unauthenticated attacker with network access to the affected service can execute arbitrary system commands on the device, potentially resulting in complete compromise of the DVR. The vulnerability is known to have been exploited in the wild by the Mirai_ptea (Rimasuta) and Mirai_aurora botnets for malware propagation and subsequent DDoS activity. The vulnerability was reported to affect firmware dating from 2016, while firmware released after 2017 appears to mitigate the issue by restricting the affected service to the localhost interface (127.0.0.1) instead of exposing it on all interfaces (0.0.0.0).
