Official 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.

Technical Analysis

CVE-2026-33788 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.

A proof-of-concept (PoC) exploit exists for CVE-2026-33788. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
