Summary

CVE-2024-25641 is a critical-severity Improper Input Validation (CWE-20) vulnerability in Cacti Cacti. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 0.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Cacti, an operational monitoring and fault management framework, contains an arbitrary file write vulnerability in versions prior to 1.2.27. The flaw resides in the import_package() function within lib/import.php, which processes XML data supplied through the Package Import feature. It accepts unvalidated filenames and file contents without filtering path traversal sequences, allowing writes to arbitrary locations under the Cacti base directory.

An authenticated user holding the Import Templates permission can exploit the issue by crafting a malicious package XML. This permits writing or overwriting files on the web server, including PHP scripts that enable remote code execution with the privileges of the web server process. The CVSS 9.1 score reflects the combination of network attack vector, high impact on confidentiality, integrity, and availability, and scope change to the underlying system.

The official patch released in Cacti 1.2.27 addresses the vulnerability by adding proper validation and sanitization within the import logic. Security advisories, including the GitHub Security Advisory and distribution notices such as those from Fedora, recommend immediate upgrade to the fixed version and review of any imported packages.

The EPSS score has reached a peak of 0.8869 with a current value of 0.8819, indicating sustained exploitation interest following disclosure.

Vulnerability Data

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, an arbitrary file write vulnerability, exploitable through the "Package Import" feature, allows authenticated users having the "Import Templates" permission to execute arbitrary PHP code on the web…

server. The vulnerability is located within the `import_package()` function defined into the `/lib/import.php` script. The function blindly trusts the filename and file content provided within the XML data, and writes such files into the Cacti base path (or even outside, since path traversal sequences are not filtered). This can be exploited to write or overwrite arbitrary files on the web server, leading to execution of arbitrary PHP code or other security impacts. Version 1.2.27 contains a patch for this issue.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing input validation through analysis or test cases.

SI-10 directly requires validity checks on information inputs, structurally preventing improper or missing validation.

Requiring documented development standards and tools can embed input-validation practices into the engineering process.

finds

Testing against a defined set of requirements and using code review plus vulnerability scanning forces validation of inputs and handling of unanticipated conditions, reducing the chance that malformed data will be accepted.

prevents

Secure-coding guidelines and mandatory security testing (including code scans) compel developers to validate and sanitize inputs at design and implementation time, lowering the incidence of malformed or malicious data reaching downstream components.

prevents

Mandating input controls that include integrity checks and input validation ensures that untrusted data is examined before use, blocking the root cause of many injection and malformed-data weaknesses.

prevents

Security-by-design principles explicitly call for data validation and sanitization at every layer, reducing the chance that malformed or malicious input will be processed without scrutiny.

prevents

Requiring language-specific secure coding standards, peer review, SAST and documented mitigation of common programming errors forces validation of all inputs before they are trusted.

none

Regular automated validation of system software and data content, combined with scanning of all inbound files, enforces input validation at the boundary before untrusted content is processed.
