Junos OS: EX Series: A vulnerability in J-Web allows an unauthenticated attacker to upload arbitrary files
ما هي
A Missing Authentication for Critical Function vulnerability in Juniper Networks Junos OS on EX Series allows an unauthenticated, network-based attacker to cause limited impact to the file system integrity.
With a specific request to installAppPackage.php that doesn't require authentication an attacker is able to upload arbitrary files via J-Web, leading to a loss of
integrity
for a certain
part of the file system, which may allow chaining to other vulnerabilities.
