GE Hydran M2 Predictable Value Range from Previous Values
The 17046 Ethernet card before 94450214LFMT100SEM-L.R3-CL for the GE Digital Energy Hydran M2 does not properly generate random values for TCP Initial Sequence Numbers (ISNs), which makes it easier for remote attackers to spoof packets by predicting these values.
CVE の解決策
GE Digital Energy has released a new version of the Ethernet option,
which resolves the identified vulnerability in newly released Hydran M2
devices. The update changes the sequence algorithm, which makes it
improbable that a TCP sequence attack could succeed. The version of
Ethernet card that implements this improvement is
94450214LFMT100SEM-L.R3-CL.
Predictable Value Range from Previous Values The product's random number generator produces a series of values which, when observed, can be used to infer a relatively small range of possibilities for the next value that could be generated.
