Command execution via cmd passed to popen
Published Jun 13, 2025 · Updated Jun 13, 2025
Command injection in eight Blink router models allows remote attackers to execute arbitrary system commands through a crafted HTTP request. The bs_SetCmd function in libshare-0.0.26.so passes the attacker-controlled cmd value to popen through /goform/set_cmd. Affected builds are BL-WR9000 2.4.9, BL-AC2100_AZ3 1.0.4, BL-X10_AC8 1.0.5, BL-LTE300 1.2.3, BL-F1200_AT1 1.0.0, BL-X26_AC8 1.2.8, BLAC450M_AE4 4.0.0, and BL-X26_DA3 1.2.7; the published request includes a user=admin cookie despite labeling the injection unauthorized.
