Other vulnerabilities in Juniper Junos OS
See all- CVE-2026-21908High
A Use After Free vulnerability was identified in the 802.1X authentication daemon (dot1xd) of Juniper Networks Junos OS and Junos OS Evolved. An authenticated, network-adjacent attacker can flap a port to crash the dot1xd process, leading to a Denial of Service (DoS), or potentially execute arbitrary code as root. The issue occurs during processing of a change of authorization (CoA) when a port bounce happens, where a freed pointer is later referenced.
- CVE-2026-21906High
A vulnerability in the packet forwarding engine (PFE) of Junos OS on SRX Series allows an unauthenticated network-based attacker to send a specific ICMP packet through a GRE tunnel, causing the PFE to crash and restart. The issue occurs when PowerMode IPsec (PMI) and GRE performance acceleration are enabled, leading to traffic loss.
- CVE-2016-1278High
Junos OS versions before 12.1X46-D50 on SRX Series devices revert to 'safe mode' after a failed upgrade to 12.1X46, allowing root CLI logins without a password. This may allow local users to gain privileges by leveraging the 'request system software' command with the 'partition' option.
- CVE-2016-1271High
In Juniper Junos OS versions before 12.1X46-D45, 12.1X47-D30, 12.3R11, 12.3X48-D25, 13.2R8, 13.3R7, 14.1R6, 14.2R4, 15.1R1, 15.1F2, and 15.1X49-D15, a vulnerability allows local users to gain privileges via crafted combinations of CLI commands and arguments. This is a different vulnerability than CVE-2015-3003, CVE-2014-3816, and CVE-2014-0615.
- CVE-2014-6450High
In Juniper Junos OS versions before 11.4R12-S4, 12.1X44-D41, 12.1X46-D26, 12.1X47-D11/D15, 12.2R9, 12.2X50-D70, 12.3R8, 12.3X48-D10, 12.3X50-D42, 13.1R4-S3, 13.1X49-D42, 13.1X50-D30, 13.2R6, 13.2X51-D26, 13.2X52-D15, 13.3R3-S3, 14.1R3, 14.2R1, 15.1R1, and 15.1X49-D10, when configured for IPv6, remote attackers can cause a denial of service (mbuf chain corruption and kernel panic) via crafted IPv6 packets.
- CVE-2015-5359High
A vulnerability in Juniper Junos OS allows remote attackers to cause a denial of service by sending a large number of BGP-VPLS advertisements with updated BGP local preference values. This affects multiple versions of the OS before their respective patches.
- CVE-2015-5358High
A vulnerability in Juniper Junos OS allows remote attackers to cause a denial of service by sending a large number of requests, triggering a TCP connection to move to the LAST_ACK state while there is more data to send.
- CVE-2014-3818High
In Juniper Junos OS versions from 9.1 to 14.1 before specific updates, a vulnerability exists that allows remote attackers to cause a denial of service through crafted transitive attributes in a BGP UPDATE. This can lead to memory corruption and a crash and restart of the RDP routing process.
