CVE-2024-13986: CWE-434 Unrestricted Upload of File with Dangerous Type in Nagios Nagios XI
Nagios XI < 2024R1.3.2 contains a remote code execution vulnerability by chaining two flaws: an arbitrary file upload and a path traversal in the Core Config Snapshots interface. The issue arises from insufficient validation of file paths and extensions during MIB upload and snapshot rename operations. Exploitation results in the placement of attacker-controlled PHP files in a web-accessible directory, executed as the www-data user.

Technical Summary
CVE-2024-13986 affects Nagios XI before version 2024R1.3.2 and involves two chained vulnerabilities: an arbitrary file upload and a path traversal in the Core Config Snapshots interface. These issues stem from insufficient validation of file paths and extensions during MIB upload and snapshot rename operations. Exploitation enables attackers to place malicious PHP files in web-accessible directories, leading to remote code execution as the www-data user. The vulnerability has a CVSS 4.0 base score of 8.7, indicating high severity. Nagios XI is a cloud service, and the vendor provides patches and manages remediation on their servers.
Potential Impact
Successful exploitation results in remote code execution on the Nagios XI server with www-data user privileges. This can allow attackers to execute arbitrary code remotely, potentially compromising the affected system and its data. The vulnerability is rated high severity with a CVSS score of 8.7. There are no known exploits in the wild at this time.
Mitigation Recommendations
A patch is available for Nagios XI version 2024R1.3.2 and later. Since Nagios XI is a cloud service, the vendor manages remediation server-side. Users should verify with Nagios that their service instance has been updated to the patched version to mitigate this vulnerability.
