CVE-2019-15958 | Cisco Prime Infrastructure and Evolved Programmable Network Manager Remote Code Execution Vulnerability

A vulnerability in the REST API of Cisco Prime Infrastructure (PI) and Cisco Evolved Programmable Network Manager (EPNM) could allow an unauthenticated remote attacker to execute arbitrary code with root privileges on the underlying operating system. The vulnerability is due to insufficient input validation during the initial High Availability (HA) configuration and registration process of an affected device. An attacker could exploit this vulnerability by uploading a malicious file during the HA registration period. A successful exploit could allow the attacker to execute arbitrary code with root-level privileges on the underlying operating system. Note: This vulnerability can only be exploited during the HA registration period. See the Details section for more information.

Base score Version Severity Vector Exploitability Impact Score source
9.8 3.1 CRITICAL
CVSS:3.1/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.

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:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
