Temporal Score: 3.5 (E:F/RL:O/RC:C)

This vulnerability can be exploited only when the following conditions are present:  

The attacker has access to the affected device and can craft special packets.

Vulnerability details:  

IKEv2 has an out-of-bounds write vulnerability due to insufficient input validation. An attacker could exploit it to craft special packets to trigger out-of-bounds memory write, which may further lead to system exceptions. 

HWPSIRT-2017-03102: 

This vulnerability can be exploited only when the following conditions are present:  

The attacker has access to the affected device and can craft special packets. 

Vulnerability details:

IKEv2 has a memory leak vulnerability due to memory release failure resulted from insufficient input validation. An attacker could exploit it to cause memory leak, which may further lead to system exceptions. 

HWPSIRT-2017-03103: 

This vulnerability can be exploited only when the following conditions are present:  

The attacker has access to the affected device and can craft special packets. 

Vulnerability details:  

IKEv2 has a DoS vulnerability due to insufficient input validation. An attacker could exploit it to cause unauthorized memory access, which may further lead to system exceptions.

HWPSIRT-2017-03110: 

This vulnerability can be exploited only when the following conditions are present:  

The attacker has access to the affected device and can craft special packets. 

Vulnerability details:

IKEv2 has an out-of-bounds memory access vulnerability due to incompliance with the 4-byte alignment requirement imposed by the MIPS CPU. An attacker could exploit it to cause unauthorized memory access, which may further lead to system exceptions.
