A vulnerability, which was classified as critical, was found in Buffalo BHR-4RV, FS-G54, WBR2-B11, WBR2-G54, WBR2-G54-KD, WBR-B11, WBR-G54, WBR-G54L, WHR2-A54G54, WHR2-G54, WHR2-G54V, WHR3-AG54, WHR-G54, WHR-G54-NF, WLA2-G54, WLA2-G54C, WLA-B11, WLA-G54, WLA-G54C, WLAH-A54G54, WLAH-AM54G54, WLAH-G54, WLI2-TX1-AG54, WLI2-TX1-AMG54, WLI2-TX1-G54, WLI3-TX1-AMG54, WLI3-TX1-G54, WLI-T1-B11, WLI-TX1-G54, WVR-G54-NF, WZR-G108, WZR-G54, WZR-HP-G54, WZR-RS-G54 and WZR-RS-G54HP. This affects an unknown functionality of the component Debug Option. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability.
