Details

A PHP External Variable Modification vulnerability in J-Web of Juniper Networks Junos OS on EX Series

and SRX Series

allows an unauthenticated, network-based attacker to control certain, important environments variables.

Utilizing a crafted request an attacker is able to modify a certain PHP environment variable leading to partial loss of integrity, which may allow chaining to other vulnerabilities.

This issue affects Juniper Networks Junos OS on SRX Series:

All versions prior to 21.4R3-S5;
22.1 versions

prior to

22.1R3-S4; * 22.2 versions

prior to

22.2R3-S2; * 22.3 versions

prior to
