CVE-2018-15379 | Cisco Prime Infrastructure Arbitrary File Upload and Command Execution Vulnerability

Exp

A vulnerability in which the HTTP web server for Cisco Prime Infrastructure (PI) has unrestricted directory permissions could allow an unauthenticated, remote attacker to upload an arbitrary file. This file could allow the attacker to execute commands at the privilege level of the user prime. This user does not have administrative or root privileges. The vulnerability is due to an incorrect permission setting for important system directories. An attacker could exploit this vulnerability by uploading a malicious file by using TFTP, which can be accessed via the web-interface GUI. A successful exploit could allow the attacker to run commands on the targeted application without authentication.

9.8 3.0 CRITICAL
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
