The improper handling of client-side parameters in J-Web of Juniper Networks Junos OS allows an malicious user to perform a number of different malicious actions against a target device when a user is authenticated to J-Web. An attacker may be able to supersede existing parameters, including hardcoded parameters within the HTTP/S session, access and exploit variables, bypass web application firewall rules or input validation mechanisms, and otherwise alter and modify J-Web's normal behavior. An attacker may be able to transition victims to malicious web services, or exfiltrate sensitive information from otherwise secure web forms. This issue affects: Juniper Networks Junos OS: All versions before 17.4R3-S3; 18.1 versions before 18.1R3-S12; 18.2 versions before 18.2R3-S6; 18.3 versions before 18.3R3-S4; 18.4 versions before 18.4R3-S6; 19.1 versions before 19.1R3-S4; 19.2 versions before 19.2R3-S1; 19.3 versions before 19.3R3-S1; 19.4 versions before 19.4R2-S2, 19.4R3; 20.1 versions before 20.1R2; 20.2 versions before 20.2R2.
