Vulnerability Information

Severity: Medium
Vulnerability Published: 2002-04-27
Patch Published: 2013-07-10
CVE [?]: CVE-2003-0001, CVE-2013-4690
CPE [?]: cpe:/o:juniper:junos

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version number, the remote Junos device has an information disclosure vulnerability. SRX1400, SRX3400, and SRX3600 services gateways pad Ethernet packets with data from previous packets instead of padding them with null bytes. A remote, unauthenticated attacker could exploit this to gain access to sensitive information, which could be used to mount further attacks.

Solution

Apply the relevant Junos upgrade referenced in Juniper advisory JSA10579.

Public Exploits
