Description

An OS command injection vulnerability in the Palo Alto Networks PAN-OS web interface enables an authenticated administrator to execute arbitrary OS commands to escalate privileges. This issue impacts: PAN-OS 9.0 version 9.0.10 through PAN-OS 9.0.14; PAN-OS 9.1 version 9.1.4 through PAN-OS 9.1.10; PAN-OS 10.0 version 10.0.7 and earlier PAN-OS 10.0 versions; PAN-OS 10.1 version 10.1.0 through PAN-OS 10.1.1. Prisma Access firewalls and firewalls running PAN-OS 8.1 versions are not impacted by this issue.

Understanding This Vulnerability

This Common Vulnerabilities and Exposures (CVE) entry provides detailed information about a security vulnerability that has been publicly disclosed. CVEs are standardized identifiers assigned by MITRE Corporation to track and catalog security vulnerabilities across software and hardware products.

The severity rating (HIGH) indicates the potential impact of this vulnerability based on the CVSS (Common Vulnerability Scoring System) framework. Higher severity ratings typically indicate vulnerabilities that could lead to more significant security breaches if exploited. Security teams should prioritize remediation efforts based on severity, exploit availability, and the EPSS (Exploit Prediction Scoring System) score, which predicts the likelihood of exploitation in the wild.

If this vulnerability affects products or systems in your infrastructure, we recommend reviewing the affected products section, checking for available patches or updates from vendors, and implementing recommended workarounds or solutions until a permanent fix is available. Organizations should also monitor security advisories and threat intelligence feeds for updates about active exploitation of this vulnerability.
