Juniper patches high-risk flaws in Junos OS
Juniper Networks has fixed several vulnerabilities in the Junos operating system used on its networking and security appliances, including a flaw that could allow hackers to gain administrative access to affected devices.
The most serious vulnerability, rated 9.8 out of 10 in the Common Vulnerability Scoring System, is located in the J-Web interface, which allows administrators to monitor, configure, troubleshoot and manage routers running Junos OS. The issue is an information leak that could allow unauthenticated users to gain admin privileges to the device.
The flaw was fixed in Junos OS 12.1X46-D45, 12.1X46-D46, 12.1X46-D51, 12.1X47-D35, 12.3R12, 12.3X48-D25, 13.3R10, 13.3R9-S1, 14.1R7, 14.1X53-D35, 14.2R6, 15.1A2, 15.1F4, 15.1X49-D30 and 15.1R3. A temporary workaround is to disable J-Web or to limit which IP addresses can access the interface.
