CVE-2024-20483 | Cisco IOS XR PON Controller Command Injection Vulnerabilities

Multiple vulnerabilities in Cisco Routed PON Controller Software, which runs as a docker container on hardware that is supported by Cisco IOS XR Software, could allow an authenticated, remote attacker with Administrator-level privileges on the PON Manager or direct access to the PON Manager MongoDB instance to perform command injection attacks on the PON Controller container and execute arbitrary commands as root. These vulnerabilities are due to insufficient validation of arguments that are passed to specific configuration commands. An attacker could exploit these vulnerabilities by including crafted input as the argument of an affected configuration command. A successful exploit could allow the attacker to execute arbitrary commands as root on the PON controller.

Base score Version Severity Vector Exploitability Impact Score source
7.2 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:H/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:H)
They need powerful rights—admin, root, or similar—before this pays off.
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.
