Description A Missing Authentication for Critical Function vulnerability in the Flexible PIC Concentrators (FPCs) of Juniper Networks Junos OS Evolved on PTX Series allows a local, authenticated attacker with low privileges to gain direct access to FPCs installed in the device.
A local user with low privileges can gain direct access to the installed FPCs as a high privileged user, which can potentially lead to a full compromise of the affected component.
This issue affects Junos OS Evolved on PTX10004, PTX10008, PTX100016, with JNP10K-LC1201 or JNP10K-LC1202:
* All versions before 21.2R3-S8-EVO,
* 21.4-EVO versions before 21.4R3-S7-EVO,
* 22.2-EVO versions before 22.2R3-S4-EVO,
* 22.3-EVO versions before 22.3R3-S3-EVO,
* 22.4-EVO versions before 22.4R3-S2-EVO,
* 23.2-EVO versions before 23.2R2-EVO.
A vulnerability allowing missing authentication for critical functions has been identified in Juniper Networks Junos OS Evolved, specifically on PTX Series routers. This issue affects all versions prior to 21.2R3-S8-EVO, as well as certain 21.4-EVO, 22.2-EVO, 22.3-EVO, 22.4-EVO, and 23.2-EVO versions. The vulnerability allows a local, authenticated attacker with low privileges to gain unauthorized access to the Flexible PIC Concentrators (FPCs) installed in the device, potentially leading to a full compromise of the affected component.
Users can upgrade to Junos OS Evolved versions 21.2R3-S8-EVO, 21.4R3-S7-EVO, 22.2R3-S4-EVO, 22.3R3-S3-EVO, 22.4R3-S2-EVO, 23.2R2-EVO, 23.4R1-EVO, or any subsequent release. For those on versions beyond End of Engineering or End of Life, consult Juniper's vulnerability fix release guidance.
