Description

Research has shown that when initial RSA certificates are generated immediately after an SRX Series Service Gateway for the Branch or LN1000 is first activated, running a release earlier than Junos 10.4R4, there exists an increased probability of the RSA certificate's public/private key pairs being duplicated on multiple devices. RSA certificates are used by J-Web. Public/private key-pairs used by SSH may also be affected by duplicate key-pair generation. This key strength weakness may make it easier for an attacker to launch a successful Man-In-The-Middle (MITM) attack.
