VAR-201501-0245

Vulnerability from variot - Updated: 2023-12-18 13:57

The stateless firewall in Juniper Junos 13.3R3, 14.1R1, and 14.1R2, when using Trio-based PFE modules, does not properly match ports, which might allow remote attackers to bypass firewall rule. Supplementary information : CWE Vulnerability type by CWE-17: Code ( code ) Has been identified. http://cwe.mitre.org/data/definitions/17.htmlA third party may bypass firewall rules. Juniper Junos is prone to a security-bypass vulnerability. An attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions. This may aid in further attacks. Juniper Junos is a set of network operating system of Juniper Networks (Juniper Networks) dedicated to the company's hardware system. The operating system provides a secure programming interface and Junos SDK. The vulnerability is caused by incorrect port matching when the program uses the Trio-based PFE module. The following releases are affected: Juniper Junos Release 13.3R3, Release 14.1R1, Release 14.1R2
