A vulnerability was 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. The affected element is the function ipRangeBlockManageRule of the file /goform/ipRangeBlockManageRule. Performing manipulation of the argument ipRangeBlockRuleName/scheduleIp/ipRangeBlockRuleIpAddr results in stack-based buffer overflow. The attack may be initiated remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
