Vulnerability description
DayBreach CVE AI Research
CVE-2026-33788 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
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.
