Archer Be800 V1
Monthly
Root-level command injection in the TP-Link Archer BE800 V1 router (firmware prior to 1.4.2 Build 260708) allows an authenticated administrator on an adjacent network to execute arbitrary OS commands with root privileges by injecting shell metacharacters through the VPN connection interface. Successful exploitation hands an attacker full control of the embedded Linux environment, enabling persistent backdoors, credential theft, and use of the router as a pivot into the connected LAN. No public exploit code or CISA KEV listing has been identified at time of analysis; a vendor-released firmware patch is available.
Unauthenticated OS command injection in TP-Link Archer BE800 V1, BE3600 V1, and AX75 V1 routers allows any LAN-adjacent attacker to execute arbitrary commands with root privileges via the parental control subsystem. Exploitation requires no credentials and no user interaction, resulting in complete device compromise including full control over routing, firewall policy, and all traffic transiting the device. Vendor-released firmware patches are available for all three affected models; no public exploit code or CISA KEV listing has been identified at time of analysis.
