CVE-2024-9463: Palo Alto Networks Expedition OS Command Injection Vulnerability

CVE-2024-9463 is rated critical with a CVSS v4.0 base score of 9.9 and affects Palo Alto Networks Expedition. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available. CISA added it to its Known Exploited Vulnerabilities catalog on 2024-11-14, which means exploitation in the wild has been observed.

Vulnerability description

An OS command injection vulnerability in Palo Alto Networks Expedition allows an unauthenticated attacker to run arbitrary OS commands as root in Expedition, resulting in disclosure of usernames, cleartext passwords, device configurations, and device API keys of PAN-OS firewalls.

  • Availability impact (subsequent systems): None. No availability impact beyond the vulnerable system.

Underlying weakness

CWE-78: Improper Neutralization of Special Elements used in an OS Command

The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.

Affected products

  • Paloaltonetworks Expedition: from 1.2.0 before 1.2.96
