A security vulnerability has been detected in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 1.0.013.001/1.0.04.001/1.0.04.002/1.1.05.003/1.2.07.001. This affects the function qosClassifier of the file /goform/qosClassifier. Such manipulation of the argument dir/sFromPort/sToPort/dFromPort/dToPort/protocol/layer7/dscp/remark_dscp leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
