An Improper Neutralization of Delimiters vulnerability in the UI of Juniper Networks Junos OS and Junos OS Evolved allows a local, authenticated attacker with high privileges to modify the system configuration. A user with limited configuration and commit permissions, using a specifically crafted annotate configuration command, can change any part of the device configuration. This issue affects:  Junos OS:  * all versions before 22.2R3-S7, * 22.4 versions before 22.4R3-S7, * 23.2 versions before 23.2R2-S4, * 23.4 versions before 23.4R2-S4, * 24.2 versions before 24.2R2-S1, * 24.4 versions before 24.4R1-S2, 24.4R2; Junos OS Evolved: * all versions before 22.4R3-S7-EVO, * 23.2-EVO versions before 23.2R2-S4-EVO, * 23.4-EVO versions before 23.4R2-S5-EVO,  * 24.2-EVO versions before 24.2R2-S1-EVO * 24.4-EVO versions before 24.4R2-EVO.
